Study on the influencing factors of fermentation of Antarctic krill shells with Lactobacillus plantarum L-45

In this study Lactobacillus plantarum L-45 was used as start strains to ferment Antarctic krill shells.The effects of carbon source,the fermentation time,the fermentation temperature and other factors on acid production of L-45 the variation and demineralization rate of krill shell were studied. The optimum fermentation conditions were as follows:fermentation time 48 h,temperature 37℃,inoculums quantity 6%,glucose added10%,and the ratio of material to liquid 1 ∶1. Under these conditions the demineralization rate was 84.6%. The obtained chitin was similar in nature and friendly to environment compared with the traditional chemical method.
