Summary: In this study, the researchers successfully increased the production of astaxanthin in Haematococcus pluvialis by combining polyethylenimine (PEI) with chitosan. The polyethylenimine concentration had an effect on astaxanthin accumulation, while the molecular weight of chitosan did not. The treatment also increased the reactive oxygen species content in cells, leading to the upregulation of enzymes involved in astaxanthin biosynthesis. The PEI-chitosan fiber treatment showed high recyclability and maintained over 90% astaxanthin production efficiency.

Summary: This study proposed a novel stimulus encoding method based on the simultaneous modulation of luminance and motion to explore the effect of moving visual flickers on SSVEP-BCI. The experimental results showed that the inclusion of horizontal motion stimulus had a negative impact on BCI performance, while a motion frequency of 0.2Hz provided the best visual experience. This suggests that moving visual stimulus can be an alternative option for SSVEP-BCIs and has the potential to develop a more comfortable BCI system.

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.
