Summary: The essential oils of P. marginatum were extracted using hydrodistillation, steam distillation, and simultaneous extraction. The chemical constituents were identified and quantified using GC/MS and GC-FID. The OEs showed significant antioxidant activity and potential toxicity to Artemia salina Leach larvae. Molecular modeling revealed the potential interactions of the main compounds, providing a basis for further research in this area.

Summary: Piper, with over 2000 species worldwide, is a diverse genus belonging to basal angiosperms. Known for its medicinal and economic importance, it presents taxonomic challenges. The Indian subcontinent is a hub of Piper diversity, with potential for future utilization, yet its conservation status remains understudied.

Summary: This study aimed to assess the post-harvest impact of UV-C irradiation on the metabolic profile of essential oils (EOs) from fresh leaves of Piper aduncum cultivated in Southeastern Brazil. The results showed that UV-C radiation can alter the relative percentage of specific chemical constituents, with a significant increase in the relative percentage of the compound dillapiole. This study suggests that UV-C irradiation may be a promising technique for enriching the dillapiole content in the essential oil of P. aduncum.

Summary: Piper species, especially Piper tectoniifolium Kunth, are potential natural sources of the bioactive compound (-)-grandisin. A new method for identifying (-)-grandisin was developed, and the molecule was found to have a vasorelaxant effect. These findings suggest that P. tectoniifolium has the potential to be a renewable source of grandisin and a template for the development of new drugs.

Summary: This study tested the hypothesis that clonal chemical heritability is crucial for the conservation of chemical uniformity in controlled monoclonal cultivation of Piper essential oils. The results showed that while clonal heritability is important for chemical homology, significant chemical plasticity can occur when cultivated from wild specimens.

Summary: Three undescribed bicyclo[3.2.1]octanoid neolignan glucosides, along with a known neolignan, were isolated from Piper crocatum leaves. Their chemical structures were elucidated through spectroscopic analyses and compared with previous data. Two compounds showed strong inhibitory effects against pyruvate dehydrogenase E1 alpha S300 phosphorylation in comparison to the positive control.

Summary: A novel bacterium G55GP(T) isolated from the gut of Madagascar hissing cockroach belongs to the Acetobacteraceae family, possibly representing a new genus. Phylogenetic analysis suggests that G55GP(T) forms a monophyletic clade with Commensalibacter, a genus also isolated exclusively from insects.

Summary: Acetobacteraceae is an economically important family of bacteria, comprising acidophilic and acetous species with different biosynthetic gene clusters in their genomes. By constructing a phylogenomic tree and predicting gene clusters, specific biosynthetic pathways can be associated with taxonomic groups, indicating the potential of Acetobacteraceae as a source of undiscovered bacterial metabolites.

Summary: This study evaluated the biological activity of extracts from marine bacteria cultures against Toxoplasma gondii and Mycobacterium tuberculosis. The Bacillus sp. INV FIR48 extract showed anti-T. gondii and anti-tuberculosis biological activity with low cytotoxicity, and peptide metabolites were detected in the extract. Marine bacteria are promising sources of natural products for anti-infective purposes, especially against prevalent diseases like toxoplasmosis and tuberculosis.

Summary: The authors isolated a polystyrene-degrading bacterium from the gut of a superworm and identified it as Pseudomonas aeruginosa DSM 50071. However, claiming that the isolated strain is the same as the original DSM 50071 strain is misleading. Additional steps should be taken to label and identify the strain accurately.

Summary: Strain G314FT, isolated from Lucilia sericata in Germany, belongs to the genus Vagococcus. It shows high sequence identity with Vagococcus bubulae, Vagococcus martis, and Vagococcus teuberi, indicating that it represents a new species of the genus. The genome of G314FT is the smallest among the closely related species and has differences in amino acid biosynthesis and carbohydrate metabolism.
