蜡状芽孢杆菌发酵南极磷虾生成活性物质的研究
Research on bioactive substances from euphausia superba fermented by Bacillus cereus
摘要
Abstract
Euphausia superba with large biological storage capacity,wide distribution,high nutritional value and so on,provide an important new marine resource of proteins to be exploited and utilized.In this paper,a strain of Bacillus cereus was isolated and screened from deep ocean mud,which was then used for the fermentation of euphausia superba.Its fermentation conditions were preliminary optimized and the antioxidant capacity of the fermentation broth was investigated,as well as the composition of the flavor compound.Under the optimized fermentation conditions for 48 hours at 30 ℃,the results were as follows: the scavenging activity of DPPH radicals 44.05%,the total phenolic content 0.059 2 mg/mL,the Fe2+ chelating ability 92.23%,the measurement of reducing power 200.13 μmol/L,the total protein content 2.952 g/100 g;the organic acid content was unique and the content of amino acid was 227.540 2 mg/mL in the fermentation broth which doubled more than 106.579 6 mg/mL in the unfermented broth.According to this research,the euphausia superba received the maximum use,and the bioactive substances in euphausia superba would play a potential role in production.关键词
