Summary: This study conducted a meta-analysis to determine the effects of feeding meat sheep dry distillers grains with solubles (DDGS). The findings suggest that feeding meat sheep 20% DDGS can improve performance, digestibility, carcass weight, and meat color. However, exceeding a 20% inclusion rate of DDGS may lead to negative effects on performance, nitrogen metabolism, and meat color.

Summary: This study aimed to analyze the changes in the profile of long-chain fatty acids in the ruminal fluid of cows during in vitro fermentation using different proportions of maize DDGS as a substrate. The use of DDGS resulted in a decrease in SFA and an increase in UFA, including oleic acid and linoleic acid. The fermentation profile with 15% and 20% DDGS proved to be the most beneficial.

Summary: This study investigated the relationship between dissolved organic matter (DOM) and microbial communities during the co-fermentation of distillers dried grains with solubles (DDGS) and sugarcane pith at different oxygen levels. The results showed that the content of DOM decreased in aerobic fermentation, while it remained relatively stable in anaerobic fermentation. Different types of organic matter were consumed at different rates in the two fermentation processes. The succession of microbial communities was influenced by pH, organic matter, and DOM.

Summary: Bioenergy, particularly bioethanol produced from food crops, presents a promising solution for environmental concerns regarding non-renewable energy sources. By utilizing hydrolyzed DDGS as a feedstock, fungal strains like Aspergillus niger exhibited higher production of cellulase and xylanase compared to bacterial strains like Bacillus subtilis. Further optimization of growth parameters and medium components using bench-top bioreactors is needed for enhanced cellulase and xylanase production.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
