Based on the analysis of 16S ribosomal RNA gene sequence DNA-DNA relatedness, strain 14 was identified as Lactobacillus casei, L. plantarum. 21, two inoculants, CH (L. plantarum) SN rhamnosus), used additives fresh wilted purple...

The contamination of fermented feeds and foods with fungi mycotoxins is a major food safety issue worldwide. Certain lactic acid bacteria (LAB), generally recognized as safe (GRAS) fermentation probiotics, are able to reduce microbial contamination. In this study, Lactiplantibacillus (L.) plantarum Q1-2 L. salivarius Q27-2 antifungal properties were screened inoculants for mixed fermenting feed, the nutritional qualities, community, feed analyzed at different periods (1, 3, 7, 15, 30 days,...

Lactic acid bacteria are commonly present in various sources and possess significant probiotic properties. They can inhibit pathogenic fungi simultaneously, making them promising candidates as bio-preservatives. This study investigated two potential strains: Lactiplantibacillus plantarum LR5-2 (isolated from fermented meat products) Lacticaseibacillus rhamnosus SQ63 infant feces). The evaluated their aggregation ability, anti-pathogenic activity, safety, tolerance to gastrointestinal...

Two strains of lactic acid bacteria, designated SU 18(T) and 83, were isolated from silage prepared with Sudan grass [Sorghum sudanense (Piper) Stapf.]. The isolates Gram-stain-positive, catalase-negative, facultatively anaerobic rods that did not produce gas glucose. exhibited ≥93.5 % DNA-DNA relatedness to each other shared the same phenotypic characteristics, which indicated they belonged a single species. DNA G+C content was 58.5-59.2 mol%. On basis 16S rRNA gene sequence analysis,...

ABSTRACT One hundred and twenty‐six strains were isolated from corn stover in Henan Province, China, of which 105 isolates considered to be lactic acid bacteria (LAB) according Gram‐positive, catalase‐negative mainly metabolic product. Analysis the 16S ribosomal DNA sequence 21 representative was used confirm presence predominant groups determine phylogenetic affiliation isolates. The sequences various LAB showed high degrees similarity those GenBank type between 99.4% 100%. prevalent LAB,...

Winter wheat is a suitable crop to be ensiled for animal feed and China has the largest planting area of this in world. During ensiling process, lactic acid bacteria (LAB) play most important role fermentation. We investigated natural population LAB whole-crop (WCW) examined quality silage (WCWS) with without inoculants. Two Lactobacillus plantarum subsp. strains, Zhengzhou University 1 (ZZU 1) selected from corn forage grass (FG commercial inoculant, were used as additives. The silages...

BACKGROUND Red pepper seeds account for 450–500 g kg−1 of the total weight and are often discarded as waste. In this study, process optimization characterization fragrant oil from roasted red seed extracted by subcritical butane extraction were carried out. RESULTS The optimal conditions a temperature 74.61 °C, time 68.65 min liquid/solid ratio 30.24:1. had refractive index (25 °C) 1.471, relative density 0.900, an acid value 1.421 mg g−1 oil, iodine 127.035 per 100 g, saponification 184.060...

For screening excellent lactic acid bacteria (LAB) strains to inhibit enterotoxigenic Escherichia coli (ETEC) K88, inhibitory activities of more than 1100 LAB isolated from different materials, and kept in the lab, were evaluated this study. Nine with inhibition zones, at least 22.00 mm (including that a hole puncher, 10.00 mm), good physiological biochemical characteristics identified by 16S DNA gene sequencing recA multiple detection, assigned Lactobacillus (L.) plantarum subsp.
