Article Abstract
Glucoside is the main antinutritional factor (ANF) of rapeseed meal. In the present study, a bacterium with high efficiency in degrading rapeseed glucoside was screened from pond water. The initial concentration of 1.0 × 10 CFU/mL bacterial solution was added to rapeseed meal and fermented for 48 h with a degradation rate of glucoside and isothiocyanate of 67% and 54%, respectively. BSY82 was identified by PacBio third-generation sequencing, and its biology was analyzed. Results showed that BSY82 belongs to . The total length of genome was 4,242,094 bp, among which 89% was coding genes (3,777,298 bp). No virulence factors were predicted, based on a comparative analysis of the strain's coding genes against known virulence factor databases. Functional analysis showed that BSY82 had the ability to produce myrosinase. The activity of myrosinase in the crude enzyme solution of the strain was 1.67 and 2.12 μmol/min by spectrophotometry and high-performance liquid chromatography (HPLC). The results indicated that BSY82 strain could be used as the optimal material in rapeseed meal fermentation detoxification process.

Type 2 diabetes mellitus (T2DM) is a a complex metabolic disorder that poses a serious threat to human health. Although polyphenol extract from rapeseed meal (RMP) has demonstrated inhibitory activity against α-glucosidase, the alleviating effects on T2DM and the underlying molecular mechanisms remain largely unexplored in T2DM. In this study, the antidiabetic effects of RMP were investigated using a T2DM mouse model induced by a high-fat diet (HFD) combined with streptozotocin (STZ) administration.

The toxicity of glucosinolate, isothiocyanate and sinapin limits canola meal's use as non-ruminant animal feed. While monoculture microbial biorefining has been explored, the potential and capability of insect-associated microbiomes in this context remain underexplored. Herein, we extracted the gut and frass extracts from canola feeding larvae of Heliothis moth (HP), cabbage white (WCF) and cabbage looper (CL).

gas production (GP) techniques, such as the extended Hohenheim gas test (eHGT), are being used to estimate the protein values of ruminant feeds and commonly apply rumen fluid obtained from rumen-cannulated animals as inoculum. This study aimed to compare rumen fluid inoculum (RI) with faecal inoculum (FI) concerning ammonia-nitrogen (NH-N) release and microbially bound nitrogen (mN). Rumen fluid was obtained from lactating dairy cows and faeces from adult wether sheep.

The inclusion of raw rapeseed meal (RSM) in broiler diets is often limited due to the presence of anti-nutritional factors. Microbial fermentation has been proposed as an effective strategy to improve the nutritional value of plant-based protein sources. This study aimed to evaluate the effects of replacing soybean meal (SBM) with either RSM or fermented RSM (FRSM) on growth performance, gut microbiota, biochemical indices, intestinal morphology, nutrient digestibility, and cecal short-chain fatty acid concentrations in broiler chickens.
