The current world energy crisis and increasing greenhouse gas emissions demand a shift from fossil-based fuels to alternative and sustainable biofuels. The innate potential of microalgae over traditional terrestrial feedstocks to provide a high-quality and sustainable fuel portfolio has been recognized. Microalgae are known to mitigate atmospheric...
The impact of vitamin D on the musculoskeletal system is well known. The diverse role of vitamin D is well supported by the functionality of vitamin D receptors and vitamin D activating enzymes (hydroxylase) present in tissues and cells. Hypovitaminosis D causes rickets, osteomalacia, hyperparathyroidism, and an increased risk of bone fracture. Vit...
Microalgae are a diverse group of microscopic, unicellular, photosynthetic algae that have colonized almost every habitat on Earth and exhibit a wide range of ecological adaptations. They have high photosynthetic efficiency and therefore generate enormous biomass under favourable conditions. Currently, the most influential factor is the modern and...
The demand for fossil fuels has resulted in their rapid depletion and rise in the fuel costs. Moreover, fossil fuels have serious negative impacts on the environment due to their harmful emissions leading to global warming. This has paved the way for research into finding a renewable alternative to fossil fuels and exploring potential biofuel feeds...
Generation of excess sludge in large quantities from wastewater treatment plant face huge problem in terms of handling and management, whereas it possess higher organic and inorganic constituents and thus it can be used as a feedstock for the generation of biofuel with proper disintegration techniques. In this regard, an effort has been made in thi...
Microalgae are highly diverse photosynthetic organisms with higher growth rate and simple nutritional requirements. They are evolved with an efficiency to adapt to a wide range of environmental conditions, resulting in a variety of genetic diversity. Algae accounts for nearly half of global photosynthesis, which makes them a crucial player for CO2...

Plastic has become one of the most crucial requirements of the modern-day living. The continuous reliance on the petroleum-based, non-biodegradable plastics has resulted in increased global environmental damage and rapid depletion of fossil fuels. Bioplastic, with remarkably similar properties to petroleum-based plastics is a promising alternative...

Abstract: Mycosporine-like amino acids (MAAs), are secondary metabolites, first reported in 1960 and found to be associated with the light-stimulated...
The current fossil fuel reserves are not sufficient to meet the increasing demand and very soon will become exhausted. Pollution, global warming, and inflated oil prices have led the quest for renewable energy sources. Macroalgae (green, brown, and red marine seaweed) is gaining popularity as a viable and promising renewable source for biofuels pro...
Photosynthetic organisms strictly depend on CO 2 availability and the CO 2 :O 2 ratio, as both CO 2 /O 2 compete for catalytic site of Rubisco. Green alga Chlamydomonas reinhardtii, can overcome CO 2 shortage by inducing CO 2-concentrating mechanism (CCM). Cells transferred to low-CO 2 are subjected to light-driven oxidative stress due to decrease...
Chlamydomonas reinhardtii is a unicellular green alga that can survive at a wide range of inorganic carbon (Ci) concentrations by regulating the activity of a CO2-concentrating mechanism (CCM) as well as other cellular functions. Under CO2 limited conditions, C. reinhardtii cells display a wide range of adaptive responses including changes in photo...
All the advancement and development witnessed since the industrial revolution has also brought broad spectrum of problems, and water pollution is one of them. Although 70% of the earth is covered by water, keeping freshwater clean is an issue of survival. The industrial pollution, a major reason for freshwater pollution, is a major growing concern....
The use of biomass energy is preferred over fossil fuels as the former is more sustainable and emits a reduced amount of greenhouse gases. Sorghum, a tropical C4 plant, is known to have a marked drought tolerance. However, very little is known about the mechanisms involved. An allied species Zea mays, also a C4 plant, is far less drought tolerant....
Microalgae have been theoretically described as a sustainable feedstock for biofuel production. However, there are still some concerns and obstacles that need to be overcome in order to translate the theoretical promise into commercial and economic success. These obstacles include a high requirement for nutrients and sustainable water source and th...
Ability of microalgae for biofuel production has been intensively investigated. Microalgae are capable of acting as sunlight driven fuel factories, which can help to convert excess carbon dioxide (CO2) into lipid and starch-based biofuels. The merits of using algae as biofuel feedstock are that multiple biofuels can be produced from single biomass...
Microalgae are diverse microorganisms that are of interest as novel sources of metabolites for various industrial, nutritional, and pharmaceutical applications. Recent studies have demonstrated transcriptional engineering of some metabolic pathways. We propose here that transcriptional engineering could be a viable means to manipulate the biosynthe...
Many eukaryotic microalgae modify their metabolism in response to nutrient stresses such as P starvation, which substantially induces storage metabolite biosynthesis, but the genetic mechanisms regulating this response are poorly understood. Here we show that P starvation-induced lipid and starch accumulation is inhibited in a Chlamydomonas reinhar...
Microalgae produce metabolites that could be useful for applications in food, biofuel or fine chemical production. The identification and development of suitable strains require analytical methods that are accurate and allow rapid screening of strains or cultivation conditions. We demonstrate the use of Fourier transform infrared (FT-IR) spectrosco...
Fourier Transform Infrared (FT-IR) spectroscopy is a robust method for macromolecular analysis and differentiation of microorganisms. However, most studies are performed in controlled conditions and it is unclear whether this tool is appropriate for the identification of eukaryotic microalgae species from variable environments. In order to address...

There is increasing interest for sustainable bioenergy production to mitigate greenhouse gas emissions and reduce reliance on fossil fuels. Biofuel can be generated from a wide variety of feedstock types including algae. Algae are an attractive feedstock for the production of liquid and gaseous biofuels that do not need to directly compete with foo...
Algae biofuels are one of the most promising areas of research today. Microalgae are an ideal biodiesel feedstock, which could eventually replace petroleum-based fuel, as they do not compete with food supply and they have enormous productivity per hectare of land, which is considered unusable for any type of farming. By using algae, one can elimina...

In context of climatic changes and soaring prices per barrel of petroleum, renewable carbon neutral, transport fuels are
needed to displace petroleum derived transport fuel, which contribute to global warming and are of limited availability.
Biodiesel derived from oil crop is a potential renewable and carbon neutral alternative to petroleum fuel. U...

Dear all,
Can some one suggest some nutrient media to grow Cryptophytes?
Hello Everyone,
I am trying to extract RNA from Chlamydomonas (Cw92) using the traditional Trizol method. My RNA yield comes up really good around 900 to 1000 ng/ul. Even the 260/280 and 260/230 ratios are close to 2 or 2.2. I am using this method for a long time and I always trust these ratios and yield given by Nano-drop. I know Nano-drop measures only nucleic acid and it cannot differentiate very well between RNA and DNA.As I am extracting this RNA for RNA sequencing, where
As I am extracting this RNA for RNA sequencing, where the integrity of RNA is important. The problem, which I came across, is that I always get good RNA and Ratio’s but when I do Bioanalyzer with the same RNA, the RIN number come out to be between 2 or 3. The RNA with such a low RIN number can not be trusted for sequencing and qPCR.
Earlier I thought RNAase might be the main problem so I tried using beta-mercaptoethanol with Trizol but there was not much improvement in RIN number. I have also checked bioanalyzer machine with other samples and they look fine on the same machine. Now I am confused, what I am doing wrong? Why am I getting low RIN numbers in chlamy samples? Does anybody have any suggestion to improve RIN number or RNA extraction protocol?
Thanks in advance.
