The availability of bacterial genome sequence information has opened up many new strategies for antibacterial drug hunting. There are obvious benefits for the identification and evaluation of new drug targets, but genomic-based technology is also beginning to provide new tools for the downstream, preclinical, optimisation of compounds. The greatest benefit from these new approaches lies in the ability to examine the entire genome (or several genomes) simultaneously and in total. In this way, one potential target can be evaluated against another, and either the total effects of functional impairment can be established or the effects of a compound can be compared across species.

Biocatalytic diversification of abietic acid in Streptomyces.
J Ind Microbiol Biotechnol

Department of Chemistry, University of Florida, Gainesville, FL, USA.
Biocatalysis provides access to synthetically challenging molecules and commercially and pharmaceutically relevant natural product analogs while adhering to principles of green chemistry. Cytochromes P450 (P450s) are amongst the most superlative and versatile oxidative enzymes found in nature and are desired regio- and stereoselective biocatalysts, particularly for structurally complex hydrocarbon skeletons. We used 10 genome-sequenced Streptomyces strains, selected based on their preponderance of P450s, to biotransform the bioactive diterpenoid abietic acid.

Global demand for food has driven expansion and intensification of livestock production, particularly in developing nations where antibiotic use is often routine. Waste from poultry production, including manure, is commonly utilized as fertilizers in agroecosystems, risking environmental contamination with potentially zoonotic bacteria and antimicrobial resistance genes (ARGs). Here, 33 bacterial isolates were recovered from broiler (n=17) and layer (n=16) chicken manure by aerobic culture using Luria Bertani agar.

Antibiotic resistance is a critical global public health issue. The gut microbiome acts as a reservoir for numerous antibiotic resistance genes (ARGs), which influence both existing and future microbial populations within a community or ecosystem. However, the differences in ARG expression between fresh and composted feces remain poorly understood.

Members of the phylum inhabit a wide range of ecosystems including soils. We analysed the global patterns of distribution and habitat preferences of various lineages across major ecosystems (soil, engineered, host-associated, marine, non-marine saline and alkaline and terrestrial non-soil ecosystems) in 248 559 publicly available metagenomic datasets. Classes , , and were highly ubiquitous and showed a clear preference to soil over non-soil habitats, while classes and showed preferences to non-soil habitats.
