Summary: Salinity is a fundamental factor in microalgal aquaculture production, affecting the lipid composition and production of microalgae. Different microalgal species show varying responses to salinity, with hypersalinity having a greater impact on lipid profiles in cultured marine microalgae. Optimizing salinity levels can lead to more sustainable microalgal production.

Summary: High temperature induces stomatal opening, but uncontrolled stomatal opening is dangerous for plants. We identified a high-temperature sensitive mutant in maize linked to a single base change in ZmMPK20 gene. The mutant exhibited increased stomatal opening and water loss rate, as well as decreased thermotolerance. Overexpression of ZmMPK20 decreased stomatal apertures, water loss rate, and enhanced plant thermotolerance.

Summary: Under combined salinity stress and high-light stresses, treatment with 0.25 mM GABA led to the highest biomass, astaxanthin production, and lipids content in Haematococcus pluvialis. GABA also increased transcript levels of biosynthesis genes, endogenous GABA and carbohydrates, while decreasing reactive oxygen species levels. The intracellular GABA was found to regulate cell growth, astaxanthin production, and lipids synthesis through mediating carotenogenesis, lipogenesis, and ROS signalling.

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.
