Optimizing mix-cultivation media of Rhodotorula glutinis and Spirulina platensis for lipid production


, : Optimizing mix-cultivation media of Rhodotorula glutinis and Spirulina platensis for lipid production. Shengwu Jiagong Guocheng 5(3): 27-31

The effects of different carbon and nitrogen source of Rhodotorula glutinis and Spirulina platensis mix-cultivation on lipid production were studied by single-factor and orthogonal design experiments. The optimum medium for mix-cultivation was obtained. In the 5L fermentor fermentation, when the concentration of glucose being lower than 10.0 g/L, feeding glucose was started with speed 600 g/L to keep the concentration of glucose (20 +/- 5) g/L. Under this condition, the final yield of lipid reached 16.0 g/L.

The concentration of intratesticular testosterone (IT-T) required for human spermatogenesis is unknown because spermatogenesis can persist despite the markedly reduced IT-T concentrations observed with LH suppression. Methods to lower IT-T further...
