Industrial vegetable oil production in Viet Nam depends on oil seeds and crude plant oils that are currently more than 90% imported. As the first step in investigating the feasibility of using microalgae to provide Viet Nam with a domestic source of oil for food and edible oil industries, fifty lipid-producing microalgae were isolated and characterized. The microalgae were isolated from water s...

Ozone exposure has been shown to increase the loss of K from Chlorella cells due to an increase in passive permeability and a depolarization of membrane potential. One factor which likely influences or can be influenced by these changes is the energy state of the cell. To study this relationship, various indicators of cell energy status were examined in the presence and absence of O(3).The acti...

The nicotinamide adenine dinucleotide-specific glutamate dehydrogenase (l-glutamate:NAD(+) oxidoreductase, EC 1.4.1.2) of Chlorella sorokiniana was purified 1,000-fold to electrophoretic homogeneity. The native enzyme was shown to have a molecular weight of 180,000 and to be composed of four identical subunits with a molecular weight of 45,000. The N-terminal amino acid was determined to be lys...

The nicotinamide adenine dinucleotide phosphate-specific glutamate dehydrogenase (NADP-GDH) of Chlorella sorokiniana was purified 260-fold to electrophoretic homogeneity in six steps. Depending on the techniques used, the native enzyme appeared to have a molecular weight of 290,000 or 410,000 and to be composed of five to seven identical subunits with a molecular weight of 58,000. The amino aci...

The extensive use of glyphosate (N-(phosphonomethyl) glycine) herbicide in agriculture is accompanied by the risk environmental contamination aquatic ecosystems. In this study, effects at different concentrations (50–500 µg ml-1) on three Chlorella species including ellipsoidea, sorokiniana and vulgaris especially relation to biomass, pigment contents photosynthetic efficiency were assessed. Af...

Microalgae cultivation in wastewater is an emerging approach to remove its contaminants and generate microalgal biomass. This study aimed screen isolate potential strains a cassava biogas effluent (CBEW) treatment system produce algal Chlorella sorokiniana P21 WB1DG were isolated from CBEW found grow by utilizing various carbon sources. Experiments conducted batch reactor using unsterilized sub...
