Growth and amylase production by Aspergillus oryzae during solid state fermentation using banana waste as substrate. Journal of Environmental Biology. 2005 Oct; 26(4): 653-6http://imsear.searo.who.int/handle/123456789/113785Aspergillus oryzae, isolated from the starch rich litter soil, produced amylase when banana fruit stalk was used as substrate in a solid state fermentation system. The effects of incubation period, pH, temperature and various carbon sources on the production of amylase were studied. A maximum yield of 380U/mg was recorded on 96th hour of incubation. The amylase is tolerant to wide range of initial culture pH values (3 to 8) and temperature (25 to 35 degrees C), with an optimum pH of 5 and temperature of 35 degrees C. In SSF addition of starch (1%) increased the amylase production, when compared with other carbon sources used.engAmylases --biosynthesisAspergillus oryzae --enzymologyBioreactorsHydrogen-Ion ConcentrationMusaTemperatureComparative Study
