Biofuel Production - Science topic

With the increase in research on the production of biofuel like bioethanol as potential replacement of gasoline whose combustion results to the release of green house gases. Will biofuels production minimize global warming?

In recent years, in connection with the inclusion of the agricultural sector in the process of green transformation of the economy as well, new solutions are being sought, created and implemented to enable the transformation of productive farms into sustainable, pro-environmental, pro-climate, organic farms growing crops and other aspects of agricultural activity in accordance with the principles of organic farming and with the simultaneous implementation of sustainable development goals. Accordingly, on a farm operated in accordance with the formula of sustainable organic agriculture, pesticides and other chemical pesticides and chemically produced fertilizers are not used in agricultural crops, energy is obtained from renewable and emission-free energy sources, water is obtained mainly from rainwater catchment facilities, organic manure and processed organic waste from composters are used to fertilize farm fields, crop rotations are used within the framework of multi-year cycles to restore high soil quality and prevent soil aridity, individual farm fields are separated by green belts and flower meadows to provide foraging areas for pollinating insects, on-farm mini-treatment plants are built to treat wastewater generated on the farm and not used in a specific way for farm purposes, etc. Besides, on a farm run according to the formula of sustainable organic farming, available technologies for the production of biofuels based on organic compost, from organic waste from agricultural crops, through which motor fuel is produced to power tractors and other agricultural machinery, should be used. These may include the construction of biogas plants, where biogas can be produced, which can then be used to power agricultural machinery. Besides, in a sustainable, ecological, pro-environmental, pro-climate farm, agro-tourism activities may also be developed, and certain preserves, food products, such as jams, juices, cheeses, etc., may be produced within the framework of a micro-production activity or manufactory, within the framework of local brands on the basis of organically produced, cultivated crops. In addition, such sustainable, organic agritourism farms may be associated within a local producers' cooperative with silos, warehouses, etc. in which crops from the cultivation of several or more locally operating farms and/or agritourism farms are stored, including or mainly, only those operating under the formula of sustainable organic farming.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

I am working on bioethanol production from lignocellulosic biomass. However, I require some clarification on the methods for calculating initial sugar concentration, sugar consumption rate, ethanol yield (in g/g and g/l). Could you please recommend simple calculations or protocols?

For biofuel production from microalgae

Ethanol-powered cars were already produced in Poland in the 1930s. The combustion of ethanol-based biofuels in biofuel stoves emits mainly CO2 and water vapour without the fumes, harmful substances produced when burning coal, wood etc. The production of agricultural crops and processed food products generates a lot of organic waste from which biofuels can be produced.

The biofuels produced in this way, which are mainly based on ethanol, can be used in biofires to heat residential buildings.

In view of the above, I address the following question to the esteemed community of researchers and scientists:

What is your opinion on this topic?

Please answer with reasons,

How do i know the % purity of crude glycerol from biodiesel plant waste?

unless using the edible materials what else can be the sources for biofuel production

Microplastics (MPs) pollution has become a global environmental concern because of their severe threat to biota. However, limited studies on the elimination of MPs pollution were reported. The conventional treatment methods such as coagulation, sedimentation, screening, and flotation were not suitable for MPs owing to their smaller size than plastic items. Hence many methods for MPs treatment, including AOPs (direct photodegradation, photocatalytic oxidation, and electrochemical oxidation) and biodegradation, have been examined.

Pretreated lignocellulose releases sugars during "Enzymatic hydrolysis" and those sugars can be used to produce biofuels. Can someone explain how can we determine the "amount of buffer" which needs to be added to the reaction mixture containing pretreated biomass and crude enzymes?

Hi,

I am currently looking for an industrial process that can use some intensification in the separation part of the process. I am very interested in intensified separation for biofuel processes (bioethanol/propanol/butanol), intensified methanol production using pressure swing to produce CO from CO2 from the revers WGS reaction, intensified carbon capture,...

If anyone has experience in these fields and can inform me if one of these could be a good dissertation, I would like to hear it! I am also curious for other processes that can use some intensification to reduce energy use/cost...

If you have any info you can also send me a message!

I am currently conducting my thesis on production of biodiesel. I have already conducted analysis on it using GC/MS and it was successful. I used n-hexane as a solvent to extract the lipids from the feedstock (a seaweed (macroalgae)) and then i reacted it with excess methanol. I was then left with 2 layers that were separated by a separating funnel. I am having concerns with regards to how well methanol dissolves the biodiesel and which layer was with biodiesel. As to my knowledge since biodiesel is more polar it will reside in the polar solvent, therefore in the methanol layer. Could someone confirm this or provide me with a paper that may help explain this?

In my thesis I used hexane to extract lipids from macroalgae followed by reaction with methanol to perform transesterification. I then left them to separate leaving 2 layers and wanted to ask if it is possible to wash both layers with chloroform and then separate the chloroform from both layers. It should be noted that in these 2 layers there is still methanol and hexane.

I determined the calorific value of bio-diesel with the help of bomb calorimeter. Is there any other methods are available to find calorific value?. thank you.

I wanted to analyze the rate of enzymatic saccharification in my pretreated biomass my usual vendor is having some issues with delivery due to COVID 19. So, I usually buy from MP Biomedicals. Since that is going to set back my work even further, I decided to look for other options and found the pricing to be unbelievably high. Just wanted to know if such crazy high pricing is normal for beta-glucosidase used in biofuel production. Maybe I am looking at the wrong options. Please let me know there are other affordable options from beta-glucosidase purchase.

Thanks in advance.

I cordially invite researchers to contribute an MS on “Value Addition in Biofuel Production Using Innovative Breeding Techniques” for the forthcoming edited book entitled “Technologies in Breeding Field Crops” (Springer Publication). Kindly send your email id for a formal invitation.

I am doing my thesis and would like to extract triglycerides from Olives or Olive Oil. I will be analysing the amount of triglycerides that are present in the olives or Olive Oil I will be testing. I would also like to extract them so that I may convert them to Fatty Acid Methyl Esters for biofuel. Does anyone know and/or have any papers that I may use? Thank you.

Basically I need a strain to transform it with some exogenous gene, I need a strain which should grow fast in less than a day, should have protocols to transform it, can be grown in an open system i.e municipal or agriculture waste, to convert it into biomass. the biomass will then be used for biofuel production. remember there should be high lipid content in biomass of that strain...

kindly guide me with such a strain which i can use in my project.

thanx in advance

we have a double-chambered MFC that produced an OCV that reached 220 mV in 1 h, and was getting higher. after 24 hours the OCV dropped down, and I don't know why.

I want to measure the generated current first to plot the I-V curve, then the power density curve.

I'm using a digital Multimeter for recording Voltage across either fixed or varied resistors.

Ash content is one of critical parameters considered for feedstock selection in biomass conversion process. Suggest suitable technology for high ash with biomass feedstock.

Hello, I am try to measure the voltage and current of a solution (typically PBS or other nutrient media) with bacteria like E coli with mediators like neutral red dye or methylene blue. Typical electrodes I'll use is two carbon or copper and aluminum combination in a single compartment setup. I know E coli K-12 shouldn't conduct current compared to other electroactive bacteria, but I'm just trying to get an understanding of setup. I've been using a digital multimeter and I can usually get a voltage measurement, although it is low and varies with the electrodes I use. However, I haven't been able to get reliable current measurements since I'll get fluctuating readings of my multi meter and I don're really know what to make of it. i read papers where this simple tool is used for current and voltage so I'm not sure what I am doing wrong. Thanks.

In regards with bio diesel

I would like to carry out research on Enzyme supported magnetically recoverable nanocatalyst systems for Biodiesel production. Homogeneous, heterogeneous and free enzyme based catalyst have main problem of catalyst separation and regeneration. Heterogeneous catalyst solves this issues but active sites of surface molecules can produce leaching in harsh reaction conditions and also it requires centrifuge and filtration techniques. This may give a chance to increase the cost of the products . This is the main challenge for any chemical reaction system. So I am considering Magnetically recoverable nano catalyst or enzyme hybrid catalyst for biodiesel production. This kind of catalyst system can be overcome the challenges of catalyst separation and regeneration of the homogeneous, heterogeneous and enzyme based catalyst system. I provided the challenging issues of biodiesel production to my Prof. But Prof. is not satisfied, my Prof. needs more challenges issues/Breakthroughs in the field. I tried my best level up to my knowledge. I cannot fulfill the requirements of my Prof.

Differential gene/protein expression profiles on same cell line always shows varied results, why does this happen?

The bio-oil was produced by fast pyrolysis of rice husk. 

Next-generation biofuels are toxic to microorganisms producing them, thus adversely affecting the production yield. The expression of efflux pumps presents a promising strategy for many biofuels like the longer chain alcohols, alkanes, alkenes and cyclic hydrocarbons, however recent studies show evidence that these are not effective at exporting short-chain alcohols. Could there be methods to make these efflux pumps less specific to solvents and still perform their function?

Dear everyone,

Recently I am working on bioethanol production from waste. I isolated cellulase enzyme from local fungi in Indonesia, however enzyme purification seems not so easy because I could found mycelium of fungi under microscope. When I conducted for hydrolysis of cellulose to glucose, I could obtained glucose in high purity. However, when I did fermentation with food grade yeast, I just obtained less than 1% of bioethanol by using GC analysis with n-propanol as internal standard.

Could anyone kindly give any advices and references for me to know the reason as well as improve my experimental condition?

Best regards,

Kurniawan

As current research on microalgae cultivation and biofuel production is booming,  weather micralgae is an option for future sustainable transportation 

I am working on an experiment to produce bioethanol using seaweed hydrolysate as a substrate. However, there are two sugars present (Rhamnose and Glucose), the yeast strain I have is Kluyveromyces marxianus  K-21. This yeast strain is able to utilize glucose, however, for Rhamnose I am not too sure since I have not carried out the experiment but on some studies it is not able to completely utilize fully Rhamnose. I have searched journals and papers about strains of yeast that are able to utilize both, such as Pichia stipitis and Candida shehatae but I am not sure specifically which strain is able to utilize both or just be able to utilize Rhamnose. I am really looking forward to your expert opinions. Thank you!

Now a days there is increasing interest among researcher and scientists to convert agriculture products to value added products. For example, agriculture by-products are used as substrates for Solid state fermentation to produce nutrients enriched feed for animals and also these by-products are used for producing various enzymes to which is used industrially. But the value addition of these by-products add extra cost to the final produce. What is your view in the above context. 

I am working on the production of biodiesel through solar energy as heat. However, I have to mix the content by electrical energy which is the drawback in my approach. I would like to transfer the synthesis of biodiesel totally on solar energy rather than using any other form of energy. Is there any approach that can mix the reactants in the flask.
