pH条件对短短芽孢杆菌FJAT-0809-GLX次生代谢物产生的影响
Effects of Initial pH Value for the Fermentation of Brevibacillus brevis FJAT-0809-GLX on the Generation of Secondary Metabolites Substances
摘要
Abstract
Components of FJAT-0809-GLX fermentation liquid inlO different initial pH values were analyzed by GC-MS. Eleven compounds with the match degree above 90 % were identified. The compounds found commonly in these 10 fermentation liquid was Hexahydro-pyrrolo [1,2-a] pyrazine-1, 4-dione. There were two sorts of functional compounds in the FJAT-0809-GLX fermentation liquids; one is volatile compounds which relate to the special aroma of this fermentation liquid, including 5-methyl-2-Furancarboxaldehyde, Maltol, Benzeneacetaldehyde, n-Hexa-decanoic acid, Oleic Acid, and 2-Hydroxy-3-methyl-2-cyclopenten-l-one. The other sort of functional compound had antiseptic and bacteriostatic effect, including Maltol, 2-Furanmethanol and Hexahydro-pyrrolo [1, 2-a] pyrazine-1,4-dione and 5-(hydroxymethyl)-2-Furancarboxaldehyde. The fermentation liquid with the initial pH value of 6 to 12 had inhibitory activity against K88. The pH value 7 had the best inhibitory activity; the diameter of inhibition zone was 20. 33mm. Different initial pH values led to different terminal pH value, and then affect the generation properties of secondary metabolites of Brevibacillus brevis FJAT-0809-GLX.关键词
