Microbial contamination and nitrite accumulation are the two major concerns in the quality control of fermented vegetables. In the present study, a lactic acid bacteria strain Lactobacillus plantarum ZJ316 (ZJ316) was inoculated during Stachys sieboldii Miq. (SSM) fermentation, and the effects of ZJ316 on the quality and bacterial community of SSM during fermentation were investigated. It was observed that ZJ316 could avoid the occurrence of the nitrite peak and maintain the nitrite content of fermented SSM at a low level. Gas chromatog.-mass spectrometry (GC-MS) results suggested that ZJ316 gave good flavor to the fermented SSM. 16S rDNA sequencing showed that Firmicutes was the dominant flora after ZJ316 inoculation, and the abundance of Proteobacteria decreased at the same time. At the level of the genus, SSM fermented by ZJ316 had a more obvious inhibitory effect on Pseudomonas on the 7th day compared with the naturally fermented SSM. Addnl., the effect of ZJ316-fermented SSM on gut microbiota modulation was also evaluated using an in vitro fecal fermentation system. The results revealed that ZJ316 had a relatively subtle influence on intestinal communities with a potentially pos. impact on probiotics such as Lactobacillus and Bifidobacterium and a neg. impact on Enterobacteriaceae. Furthermore, SSM fermented by ZJ316 promoted the production of short-chain fatty acids (SCFAs) in the human intestine. These results demonstrate that L. plantarum ZJ316 can be used as a good starter in the fermentation process of pickles. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Recommanded Product: Isopentyl hexanoate).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: Isopentyl hexanoate
