Production of high-density Chlorella culture grown in fermenters

Popis výsledku v původním jazyce

The freshwater microalga Chlorella vulgaris was grown heterotrophically in fed-batch 50-600-L fermenters at 36A degrees C, on aerated and mixed nutrient solution with urea as a nitrogen and glucose as a carbon and energy source. Cell density increased from the initial value 6.25 to 117.18 g DW L-1 in 32 h in the fermenter 50 L at a mean growth rate 3.52 g DW L-1 h(-1). The DW increase in the fermenter 200 L was from 7.25 to 94.82 g DW L-1 in 26.5 h at a mean growth rate 3.37 g DW L-1 h(-1). Mean specific growth rate mu was about 0.1 h(-1) in the both fermenters, if nutrients and oxygen were adequately supplied. The DW increase in the fermenter 600 L was from 0.8 to 81.6 g DW L-1 in 66.5 h at a mean growth rate 1.22 g DW L-1 h(-1) and mu = 0.07 h(-1). Alimitation of the cell growth rate in 600 L fermenter caused by a low dissolved oxygen concentration above cell densities higher than 10 g DW L-1) occurred. Specific growth rate decreased approximately linearly with increasing glucose co
