A strain of Bacillus sp. coded JMa5 was isolated from molasses contaminated soil. The strain was able to grow at a temperature as high as 45°C and in 250 g/l molasses although the optimal growth temperature was 35–37°C. Cell density reached 30 g/l 8 h after inoculation in a batch culture with an initial concentration of 210 g/l molasses. Under fed-batch conditions, the cells grew to a dry weight of 70 g/l after 30 h of fermentation. The strain accumulated 25–35%, (w/w) polyhydroxybutyrate (PHB… CONTINUE READING
