Dynamic changes in the gel properties, microbial community, and volatile flavor profile of Spanish mackerel () sausages inoculated with CY1-2.

Spanish mackerel is an important economic fish species in China, but corruption undermines its overall economic value. Fermentation serves as a crucial technique for preserving perishable fish in developing countries. This study aimed to examine the dynamic changes in the gel properties, physicochemical properties, microbial diversity, and volatile flavor compounds (VFCs) of Spanish mackerel sausages inoculated with CY1-2 during fermentation.

Purification, characterization and action mechanism of plantaricin JY22, a novel bacteriocin against produced by JY22 from golden carp intestine.

A novel bacteriocin-producing strain, JY22 isolated from golden carp intestine, was screened and identified by its physiobiochemical characteristics and 16S rRNA gene sequence analysis. This bacteriocin, named plantaricin JY22, was purified using ethyl acetate extraction and gel filtration. Its molecular weight was approximately 4.

Antifungal activity of C10 against and its application in promotion of defense responses in muskmelon ( L.) fruit.

The antifungal effect of C10 on pink rot caused by and its application in muskmelon fruit were investigated. Cell-free supernatant (CFS) produced by C10 strongly inhibited the growth of and seriously damaged the structures of spores and mycelia of . Acid compounds produced by C10 were the major antifungal substances and exhibited a narrow pH range from 3.

Purification and antibacterial mechanism of fish-borne bacteriocin and its application in shrimp (Penaeus vannamei) for inhibiting Vibrio parahaemolyticus.

Vibrio parahaemolyticus: is recognized as the main cause of gastroenteritis associated with consumption of seafood. Bacteriocin-producing Lactobacillus plantarum FGC-12 isolated from golden carp intestine had strong antibacterial activity toward V. parahaemolyticus.

Involvement of Acylated Homoserine Lactones (AHLs) of Aeromonas sobria in Spoilage of Refrigerated Turbot (Scophthalmus maximus L.).

One quorum sensing strain was isolated from spoiled turbot. The species was determined by 16S rRNA gene analysis and classical tests, named Aeromonas sobria AS7. Quorum-sensing (QS) signals (N-acyl homoserine lactones (AHLs)) were detected by report strains and their structures were further determined by GC-MS.

Antimicrobial effect and membrane-active mechanism of tea polyphenols against Serratia marcescens.

In this study, we investigated the antimicrobial effect of tea polyphenols (TP) against Serratia marcescens and examined the related mechanism. Morphology changes of S. marcescens were first observed by transmission electron microscopy after treatment with TP, which indicated that the primary inhibition action of TP was to damage the bacterial cell membranes.

Screening of Lactobacillus strains for their ability to bind benzo(a)pyrene and the mechanism of the process.

In order to investigate the binding ability of Lactobacillus strains to Benzo(a)pyrene (BaP), 15 strains were analysed. L. plantarum CICC 22135 and L.

Characterization of soybean protein hydrolysates able to promote the proliferation of Streptococcus thermophilus ST.

How soybean protein hydrolysates (SPHs) to favor the growth of S. thermophilus ST were investigated. Hydrolyzed soybean protein was fractionated to 4 fragments, that is, SPH-I, SPH-II, SPH-III, and SPH-IV according to their molecular weight sizes.
