Summary: Biological treatment is an efficient and economical method to remove thiamphenicol (TAP) residues from the environment. The discovery of TAP-degrading bacteria and the decryption of its biodegradation mechanism is beneficial for enhancing the biological removal of TAP. Sphingomonas sp. CL5.1 was found to be capable of catabolizing TAP, degrading a significant amount of TAP in a short time period. Additionally, a novel metabolism pathway of TAP was constructed with potential enzymes predicted for TAP metabolism in strain CL5.1.

Summary: A secondary metabolism regulator, NPD938, was utilized to modify the secondary metabolite profile in Fusarium sp. RK97-94, resulting in the detection and identification of three lucilactaene analogues. Among these analogues, dihydrolucilactaene and 13 alpha-hydroxylucilactaene exhibited potent antimalarial activity, providing insights into their potential as lead compounds for malaria treatment.

Summary: Three novel bacterial strains belonging to the genus Sphingomonas were isolated from healthy citrus leaves collected in Guangdong Province, China. Based on phenotypic, genotypic, and chemotaxonomic analyses, these strains represent three new species, which are named Sphingomonas folli sp. nov., Sphingomonas citri sp. nov., and Sphingomonas citricola sp. nov.

Summary: Chemical investigation of Streptomyces sp. NA07423 led to the discovery of two unreported macrolactams, nagimycins A(1) and B (2). Their structures were elucidated by NMR, HRESIMS, X-ray crystallography, and comparison of experimental and theoretical ECD spectra. The nagimycins have a unique butenolide moiety rarely found in ansamycin antibiotics. Genome analysis revealed the putative biosynthetic gene cluster for nagimycins, and a likely biosynthetic pathway was proposed. Notably, compounds 1 and 2 exhibited potent antibacterial activity against two pathogenic Xanthomonas bacteria.

Summary: The study revealed that a yeast strain capable of degrading phenol entered the viable but nonculturable (VBNC) state under high concentrations of contaminants, and the resuscitation of VBNC cells restored their degradation performance. Compared to normal cells, significant morphological, surface, and physiological changes were observed in the VBNC cells.

Summary: In this study, label-free quantitative proteome analysis was used to investigate the protein expression difference in Comamonas sp. QT12 strain under the conditions of 3-aminobenzoic acid (3AB) and citric acid/ammonium chloride. The mab cluster associated with 3AB degradation was identified, and two genes in the cluster were found not to be key genes in 3AB degradation. These findings provide important insights into the molecular mechanisms underlying the cellular response of 3AB degradation in Comamonas bacterium.

Summary: The emergence of new virulent and aggressive pathotypes of Puccinia striiformis f. sp. tritici has caused the breakdown of stripe rust resistance in Indian wheat cultivars. This study investigates the resistance levels of different cultivars and the genetic factors contributing to resistance. The results show that certain cultivars and genes provide resistance, but the resistance decreases as the level of resistance increases. The interaction between major and minor genes/QTLs plays a significant role in residual resistance.

Summary: This study aimed to evaluate the biodegradation efficiency of anthracene by selected marine bacteria. Sphingomonas sp. KSU05 was identified as the most effective biodegrading strain, capable of surviving up to 500 mg/L of anthracene and rapidly degrading it within 96 hours. Optimization of culture conditions enhanced the anthracene biodegradation to 90.0% at pH 7.0, 0.3 mM tween-80 concentration, and 5.5% glucose concentration.

Summary: Removing microcystins (MCs) safely and effectively is a global problem due to their hazardous effects on the environment and public health. This study investigated the binding mode of MlrC with linearized MCs and proposed a possible catalytic mechanism based on experimental results and literature survey. The findings provided new insights into the molecular mechanisms of MlrC enzyme and laid a theoretical foundation for further MCs biodegradation studies.
