Microalgae are considered to be a potential major biomass feedstock for biofuel due to their high lipid content. However, no correlation equations as a function of initial nitrogen concentration for lipid accumulation have been developed for simplicity to predict lipid production and optimize the lipid production process. In this study, a lipid accumulation model was developed with simple param...

Mutants of Chlorella sorokiniana selected for resistance to the methionine analogue ethionine took up ethionine at the same rate as did the wild type strain. Cells of two ethionine-resistant mutants produced severalfold higher levels of free methionine and cysteine than did wild type cells.Exogenous methionine had no apparent effect on free methionine production in a mutant that produces excess...

Ampicillin sodium salt (AMP) is commonly and effectively used to prevent bacterial infection in algal culture, but the response of strains AMP has not been investigated. In this study, Chlorella sorokiniana was selected evaluate influence on algae. enhanced contents chlorophyll two fatty acids, myristic acid (C22:1N9) tetracosanoic (C6:0), inhibited growth, carotenoid production, 16 acids C. so...

Protein extraction, precipitation, and recovery methods were evaluated by this study using a green alga—Chlorella sorokiniana. A mechanochemical cell disruption process was applied to facilitate protein extraction from microalgal biomass. Optimization of the resulted in milling conditions that achieved 52.7 ± 6.45%. The consequent acid precipitation method optimized recover 98.7% proteins slurr...

Photo-biohydrogen by microalgae is attractive sustainable energy caused the utilization of solar and water. However, due to oxygen (O 2 ) sensitive hydrogenase (HydA) activity, effective control O light intensity critical for achieving photosynthetic hydrogen (H production. Here we demonstrate continuous algal H production using acetate-enriched fermenter effluent, complete cessation without su...
