Abstract: | The effect of different culture conditions on thermostable lipase production byBacillus sp. was studied in shake flasks. A maximum enzyme activity of 67–75 nkat/mL was observed in a medium consisting of 0.5% soybean
flour and 0.1% stearyl glycerol esters or natural fats. A lipase activity of about 117 nkat/mL was established when the cultivation
was carried out in laboratory fermentor at 20% minimal dissolved oxygen level, the enzyme production being increased 1.5 fold
compared to that in a flask culture. |
