Phylogenomic analyses of the genus : description of four novel genera.

The genus comprises 57 species (in February 2024) that are important components of ecosystems and are widely used in biotechnology, especially pharmaceuticals. Phylogenetic analysis of the family (based on the 16S rRNA gene sequence) allowed us to group members of different genera into separate clades; however, the genus was divided into three separate clades. Such phylogenetic heterogeneity could be due to the limitations of 16S rRNA gene analysis.

The use of machine learning for the determination of a type/model of firearms by the characteristics on cartridge cases.

Cartridge cases are commonly collected at crime scenes involving firearms. One of the stages in forensic examination is the determination of the type and model of firearms based on the class characteristics of these cartridge cases. A firearm examiner evaluates the class characteristics on the basis of their knowledge and experience, and by referring to collections of cartridge cases representing class characteristics of different firearms, special databases and reference books.

The Impact of Heterologous Regulatory Genes from Lipodepsipeptide Biosynthetic Gene Clusters on the Production of Teicoplanin and A40926.

StrR-like pathway-specific transcriptional regulators (PSRs) function as activators in the biosynthesis of various antibiotics, including glycopeptides (GPAs), aminoglycosides, aminocoumarins, and ramoplanin-like lipodepsipeptides (LDPs). In particular, the roles of StrR-like PSRs have been previously investigated in the biosynthesis of streptomycin, novobiocin, GPAs like balhimycin, teicoplanin, and A40926, as well as LDP enduracidin. In the current study, we focused on StrR-like PSRs from the ramoplanin biosynthetic gene cluster (BGC) in ATCC 33076 (Ramo5) and the chersinamycin BGC in DSM 44151 (Chers28).

sp. nov., producing the glycopeptide antibiotic A477.

In 1973, Eli Lilly and Company described the filamentous actinomycete producing the glycopeptide antibiotic A477 as an species on the basis of its morphological and physiological features and deposited it as NRRL 3884. In this paper, we report that the phylogenetic analysis based on the 16S rRNA gene sequence and the whole genome phylogenomic study indicate that NRRL 3884 forms a distinct monophyletic line within the genus , being most closely related to NBRC 14524 [99.6 % 16S rRNA gene similarity, 89.

Bacterial community and culturable actinomycetes of Phyllostachys viridiglaucescens rhizosphere.

During the course of development plants form tight interactions with microorganisms inhabiting their root zone. In turn, rhizosphere bacteria, in particular members of the phylum Actinomycetota, positively influence the host plant by increasing access to essential nutrients and controlling the pathogenic microorganism's population. Herein, we report the characterisation of the rhizosphere associated actinobacteria community of Phyllostachys viridiglaucescens growing in the Nikitsky Botanical Garden (Crimean Peninsula, Ukraine).
