The cellular and humoral immune responses of mice inoculated with rabies virus and treated with the Bacillus of Calmette-Guérin, Avridine and Propionibacterium acnes were evaluated in this paper. There was a higher percentage of surviving mice in groups submitted to P. acnes treatment. Lower levels of interferon-gamma (IFN-gamma) were found in infected mice. The intra-pad inoculation test (IPI) was not effective to detect cellular immune response, contrary to the results found in MIF reaction. The survival of mice did not present correlation with the levels of antirabies serum neutralizing (SN) antibodies titers, IFN-gamma concentration and MIF response.

Levan is a fructan-type homopolysaccharide that has gained increasing attention due to its unique properties and promising applications. It is a fructose-based polymer produced through microbial fermentation by diverse microorganisms, including bacteria, yeasts and archaea. The ongoing research on levan mainly focuses on optimizing production processes, elucidating its biological functions, and uncover novel applications.

The widespread commercialization of genetically modified (GM) crops makes it important to assess the potential impact of Bacillus thuringiensis (Bt) on non-target organisms. Pardosa astrigera is an important predator in agroforestry ecosystems, and female and male spiders may react differently to Bt toxins due to their different activity habits and nutritional requirements. In this study, we found that exposure to Cry2Aa protein did not affect the survival and body weight of P.

Ginseng peptides, small molecule active ingredients in ginseng, are mainly extracted naturally or synthesised chemically, but high costs and difficulties hinder further research. In this study, a ginseng hexapeptide FKEHGY, named antitumor peptide 0601 (AT0601) and its five tandem sequence repeats AT0605, were expressed in Bacillus subtilis WB600 for the first time, and the bioactivity study showed that the anticancer activity of AT0605 was even significantly higher than that of AT0601 for colon cancer CT26 cells, with IC50s of 16.82±1.

Toxic and carcinogenic compounds, such as synthetic dyes and polyphenols, were widely employed and released as pollutants in a variety of industries, including textiles, food, and cosmetics. Biological oxidation process that used oxidizing enzymes to breakdown pollutant compounds were environmentally favorable. However, due to the cell toxicity of metal ions supplements used for the biosynthesis of oxidizing enzymes like laccase, their efficient application for biological degradation is limited.

The control of internal pollution was important throughout the restoration of the lake, especially the removal of sediment internal nitrogen. Experiments involving incubation were conducted in this study to investigate the effects of iron remediation on nitrogen in both water and sediment. Adding iron with varying dosage had different effects on the nutrients content and other properties of water and sediment in remediation.
