Rising oil prices and climate change have resulted in more emphasis on research into renewable biofuels. In this study, different water samples were collected from local vicinities for the isolation of isolates microalgae to check their potential towards production biofuel by addition chemical substrates. Five concentrations ascorbic acid iron (III) chloride (0, 1, 2.5, 5 & 10 µM) are used ...

Chlorella is widely used for its fast growth rate and easy cultivation with 14–30% lipid content 36–59% dry weight. Thus, sodium hydroxide to increase carbon consumption, biomass, metabolites productions in microalgae. This study was conducted observe the effect of addition on biomass production photoautotrophic cultivated sorokiniana. Microalgae C.sorokiniana (LIPI12-Al016) obtained from cultu...

Hydrolysate prepared from the chemical hydrolysis of water hyacinth biomass contains a high amount solubilised carbohydrate and nutrients. This hydrolysate was utilised as medium for cultivation two strains Chlorella sorokiniana, isolated municipal wastewater treatment plant using different media, i.e., BG-11 Knop’s medium. Different light intensities, light–dark cycles, various concentrations ...

Ozone-treated cells of the photosynthetic green alga Chlorella sorokiniana var. pacificensis exhibit an exponential decline in viability, as measured by their ability to form colonies on agar plates. Postexposure conditions appear to have little, if any, effect on this rate of decline. Except in young (early exponential phase) cells, culture age did not affect this rate. The decline in cell via...

The oxygen-resistant strain of Chlorella sorokiniana (Shihira and Krauss), distinguished by its ability to grow autotrophically under high partial pressures of oxygen, was studied and partially characterized in heterotrophic culture. Ultrastructural analysis of glucose-grown oxygen-resistant strain and wild type cells reveals that osmiophilic deposits (possibly polyphosphate) are present only i...

To figure out the torrefaction characteristics and weight loss dynamics of microalgae residues, the thermogravimetric analyses of two microalgae (Chlamydomonas sp. JSC4 and Chlorella sorokiniana CY1) residues are carried out. A parameter of torrefaction severity index (TSI) in the range of 0-1, in terms of weight loss ratio between a certain operation and a reference operation, is defined to in...

The present study investigated the feasibility of bioCO(2) sequestration using Chlorella sorokiniana. It was found that 5% CO(2) (v/v) in air was the most suitable concentration for the growth of this organism. At this concentration, the maximum rate of CO(2) sequestered and the biomass obtained were found to be 1.21 g L(-1)d(-1) and 4.4 g L(-1) respectively. Modeling and simulation of the grow...

BACKGROUND AND OBJECTIVES Chlorophyceae are important constituents of marine phytoplankton. The taxonomy of Chlorophyceae was traditionally based solely on morphological characteristics. In the present research project, genetic diversity was investigated to analyze five species of Chlorophyceae from waters of the Persian Gulf. MATERIALS AND METHODS A clone library of the ribosomal small subun...

The genus Chlorella is a widely employed microalga for biodiesel, as it can be grown using photo/mixo/heterotrophic mode of cultivation. The present investigation was undertaken with the hypothesis that addition of different substrates (amino acids, carbon sources, vitamins) along with reducing agents may aid in diverting Acetyl CoA to malonyl CoA or fatty acid biosynthesis, under mixotrophic c...
