Optimizing some factors affecting alkaline protease production by a marine bacterium Teredinobacter turnirae under solid substrate fermentation

Production of extracellular alkaline protease by a shipworm bacterium Teredinocabcter turnirae, under solid substrate fermentation (SSF) was optimised. Soybean was used as a sole carbon and/or nitrogen source. The maximum protease yield (1950 U/ml) was achieved with optimised parameters such as coar...

Summary:Production of extracellular alkaline protease by a shipworm bacterium Teredinocabcter turnirae, under solid substrate fermentation (SSF) was optimised. Soybean was used as a sole carbon and/or nitrogen source. The maximum protease yield (1950 U/ml) was achieved with optimised parameters such as coarse size of soybean (2 mm), concentration of soybean 1% (w/v), unadjusted pH of the medium 7.34, inoculum level 2.5% (v/v) and agitation rate 120 rpm. Sixty percent of higher production was achieved after optimising the process parameters.
