To date, the field of microalgae has been slowly evolving and expanding to accommodate various industries from food and feed to biofuel production coupled with wastewater treatment which subsequently allowed greater access of water for daily usage. This technology is gradually proving its value, despite its limited use in the market. With the deple...
The growing potential of sustainable materials such as polyhydroxyalkanoates (PHAs), polylactic acid (PLA), alginate, carrageenan, and ulvan for bioplastics production presents an opportunity to promote a sustainable circular economy. This review investigates their properties, applications, and challenges. Bioplastics derived from algae offer an en...
Surfactants have always been a prominent chemical that is useful in various sectors (e.g., cleaning agent production industry, textile industry and painting industry). This is due to the special ability of surfactants to reduce surface tension between two fluid surfaces (e.g., water and oil). However, the current society has long omitted the harmfu...
This study reports optimization and simulation of biodiesel synthesis from waste cooking oil through supercritical transesterification reaction without the use of any catalyst. Although the catalyst enhances the reaction rate but due to the presence of water contents in waste cooking oil, the use of catalyst could cause a negative impact on the bio...
Microalgae farming is still in its infancy phase to implement internet-of-things (IoT) technologies. Spirulina microalgae was selected to be investigated in this study because it is the most commercially viable microalgae for large-scale production. There are various methods to measure the biomass concentration of microalgae. However, the conventio...
Macroalgae, with short growth cycles, and high CO2 fixation capacity, are third-generation biomass mainstays that play an essential role as a global carbon sink. Macroalgal biochar plays a crucial role in soil improvement, pollutant adsorption, electrodes, and capacitors, and it has already contributed to both ecological and economic fields. Howeve...
Management of late blight of potato incited by Phytophthora infestans remains a major challenge. Coevolution of pathogen with resistant strains and the rise of fungicide resistance have made it more challenging to prevent the spread of P. infestans. Here, the anti-oomycete potential of Bacillus velezensis VB7 against P. infestans through pan-genome...

Distillation has relatively low thermodynamic efficiency, so it is a prime target for process intensification studies. The current research aims to study exergy losses in various heat-integrated distillation columns. A conventional industrial-scale i-butane/n-butane fractionator has been selected as a case study for the comparison of the performanc...
There has been an urgent need to tackle global climate change and replace conventional fuels with alternatives from sustainable sources. This has led to the emergence of bioenergy sources like biofuels and biohydrogen extracted from microalgae biomass. Microalgae takes up carbon dioxide and absorbs sunlight, as part of its photosynthesis process, f...
The focus of this study is to enhance the protein fouling resistance, hydrophilicity, biocompatibility, hemocompatibility and ability of the membranes and to reduce health complications like chronic pulmonary disease, peripheral vascular disease, cerebrovascular disease, and cardiovascular disease after dialysis, which are the great challenges in H...
Arthrospira platensis (A. platensis) aqueous extract has massive amounts of natural products that can be used as future drugs, such as C-phycocyanin, allophycocyanin, etc. This extract was chosen because of its high adaptability, which reflects its resolute genetic composition. The proactive roles of cyanobacteria, particularly in the medical field...
Background
Microalgae have been a hot research topic due to their various biorefinery applications, particularly microalgae as potential alternative nutraceuticals and supplements have a large and rapidly growing market. However, the commercial production is limited due to high processing cost, low efficiency, and scale up of biomass production.
O...
Biosurfactant is one of the emerging compounds in the industrial sector that behaves similarly with their synthetic counterparts, as they can reduce surface and interfacial tension between two fluids. Their unique properties also enable biosurfactant molecules to be able to clump together to form micelles that can capture targeted molecules within...

Does anyone know what microorganism is this? There seems to have some blue colour on it.
Hi all, recently I bought a bottle of fresh and live spirulina from shopee. However, I don't know what medium they used to grow the spirulina and I want to prepare my own medium. What do you all recommend on how to mix and continue the growth of spirulina? The absorbance of the bottle of spirulina from shopee is about 0.7. I have tried to add 100 ml of fresh spirulina into 400 ml of zarrouk medium but it seems to be dying. Any advice or methods do you recommend?
