Summary: Glycolipid-type biosurfactants have shown potential as natural anticancer agents. In this study, mono-rhamnolipids produced by a recombinant strain of Pseudomonas aeruginosa were used to treat colorectal cancer cells. The mono-rhamnolipids significantly reduced the viability of the cancer cells and showed higher cytotoxicity compared to Piceatannol, another natural anticancer agent. The compounds appeared to induce necrosis in the cancer cells.

Summary: This study measured the high-pressure adsorption isotherms of two coal samples to investigate the methane adsorption process and mechanisms in coal. The results showed that micropore filling and surface adsorption are the primary adsorption mechanisms for supercritical methane in coal, with micropore filling occurring in pores smaller than 1.1 nm and surface adsorption occurring in 1-2 nm pores. Micropore filling adsorption plays a significant role in the overall methane adsorption, and the nano-confined effect and low water saturation contribute to the enrichment of free gas in deep coalbed methane (CBM). These findings provide insights into the occurrence behavior of unconventional natural gas in reservoirs.

Summary: In this study, the pore structure characteristics of No. 3 coal seams in Qinshui Basin after microbial treatment were analyzed. It was found that microorganisms participated in the degradation of coal reservoirs and promoted the production of methane gas. The modification of meso-macropores was more significant, resulting in stabilized pore diameter, smoother pores, decreased specific surface area, and increased pore volume, which are beneficial for the adsorption and production of coalbed methane (CBM) after microbial treatment.

Summary: This study investigated the water vapor sorption behavior in different maturity coal samples and identified two types of water adsorption mechanisms: attachment to oxygen functional groups and pore filling in hydrophilic and hydrophobic pores, respectively. The differences in water adsorption characteristics were found to be influenced by pore volume and the proportion of hydrophilic pores. The results also showed that water adsorption on methane adsorption in coal was attributed to the amount and proportion of hydrophilic pores.

Summary: Enhancing coal permeability through formation heat treatment is an effective method for coalbed methane exploitation. The process involves removing residual water and inducing cracks in the coal structure, significantly increasing permeability. Additionally, the stimulation mechanisms consist of alleviating aqueous phase trapping, weakening coal mechanical properties, and inducing coal fracture to produce more gas flow channels.

Summary: Azospirillum brasilense is a non-photosynthetic bacterium that produces bacterioruberin type of carotenoids. While genes involved in spirilloxanthin pathway were absent, this bacterium contains genes (crtC and crtF) responsible for the biosynthesis of bacterioruberins. Characterization of carotenoids in A. brasilense Cd using chromatography and mass spectrometry revealed the presence of unique carotenoids such as 19'-hydroxyfucoxanthinol and 8'-apoalloxanthinal.

Summary: Azospirillum brasilense has the ability to cometabolize ethanol in medium containing fructose or glycerol as a carbon source, leading to enhanced production of alcohol dehydrogenase and aldehyde dehydrogenase. In glycerol-supplemented medium, a new paralog of alcohol dehydrogenase (ExaA1) is synthesized to facilitate the utilization of ethanol by A. brasilense. The expression of exaA1 is induced by glycerol and negatively regulated by the RpoH2 sigma factor.

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.
