Biomass and Lipid Content of Heterotrophic Spirogyra sp by Using Cassava Starch Hydrolysate
نویسنده
چکیده
Research has been conducted on Spirogyra sp heterotrophic cultivation by providing cassava starch hydrolysate (CSH) as a carbon source under dark condition. The purpose of this research was to obtain the concentration of CSH which could increase biomass concentration and lipid content of Spirogyra sp under heterotrophic cultivation. The treatment of CSH (15 g/L) could produce the highest biomass concentration and lipid content of Spirogyra sp. After 6 weeks cultivation, the maximal biomass concentration and lipid content of 12.03 g/L and 5.23 % respectively was obtained in the culture added 15 g/L cassava starch hydrolysate under dark condition, which higher than under light condition. This study revealed that algae Spirogyra sp exhibit enhanced biomass concentration and lipid content under heterotrophic cultivation, in the presence of cassava starch hydrolysate.

Investigations were carried out with the aim of producing L-glutamic acid from Brevibacterium sp. by utilizing a locally available starchy substrate, cassava (Manihot esculenta Crantz). Initial studies were carried out in shake flasks, which showed that even though the yield was high with 85-90 DE (Dextrose Equivalent value), the maximum conversion yield (~34%) was obtained by using only partia...

BACKGROUND Biodiesel production from oleaginous microalgae shows great potential as a promising alternative to conventional fossil fuels. Currently, most research focus on algal biomass production with autotrophic cultivation, but this cultivation strategy induces low biomass concentration and it is difficult to be used in large-scale algal biomass production. By contrast, heterotrophic algae a...
