Bacillus subtilus WSH-062 could produce extracellular poly(vinyl alcohol)(PVA)-degrading enzyme(PVAase) in the flask culture.Optimization of culture conditions was carried out through mono-factor and orthogonal experiments.The results showed that the enzyme produced by this strain was an induced enzyme.The mixed nitrogen sources(the ratio of NaNO3 to yeast extract was 1:1) with concentration of 2 g/L were favorable for cell growth and enzyme synthesis.The results of orthogonal experiment showed… CONTINUE READING
