Summary: Exhausted sugar beet pulp pellets were utilized for lactic acid fermentation. Lactobacillus plantarum showed higher lactic acid production compared to Lactobacillus casei, with the highest concentration achieved with the addition of yeast extract and pH control with CaCO3. A kinetic model was developed to predict substrate and product evolution based on pH variation in the hydrolysate with CaCO3 addition.

Summary: An adapted Bacillus coagulans strain was developed for lactic acid production from lignocellulosic biomass. Without detoxification, actual corn cob hydrolysates were effectively fermented to lactic acid within 60 hours. The strain was capable of degrading nine phenolic compounds, except for vanillic acid, with the highest tolerance reported for ferulic acid and p-coumaric acid in anaerobic microbes. A proposed degradation pathway showed the conversion of phenolic aldehydes to phenolic alcohol and their complete degradation. This work provides insights into the microbe phenolic degradation pathway and enables industrial lactic acid production from lignocellulosic biomass.

Summary: The addition of Bacillus coagulans (BC) can improve the fermentation quality of alfalfa silage, especially when used in combination with Lactobacillus plantarum (LP). The addition of BC and LP can decrease the pH values and increase the lactic acid concentration in the silage, as well as preserve more water-soluble carbohydrates. Furthermore, the addition of BC increases the abundance of Lactobacillus and decreases the abundance of Enterococcus, improving the fermentation quality.

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.

Summary: This study investigated the operation of a 1000L microalgae-based membrane photobioreactor system for continuous secondary wastewater treatment. The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
