Abstract:
Antimicrobial resistance (AMR) poses a global public health threat, and the increase in resistance to “last-resort drugs,” such as carbapenems, is alarming. Wastewater has been flagged as a hot spot for AMR evolution. Comamonas spp. are among the most common bacteria in wastewater and play a role in its bioaugmentation.

Abstract:
Understanding the role of microorganisms in the formation of regolith-hosted rare earth element (REE) deposits is beneficial for improving the metallogenic theory and deposit exploitation, given that such deposits absolutely exist in subtropical regions with strong microbial activities. Little is known of the microbial community composition and its contribution to REE mineralization in this kind of deposit.

Abstract:
Soil biogeochemical processes are critical to plant growth and water quality and are substantially disturbed by wildfire. However, soil responses to fire are difficult to predict.

Abstract:
Pediocin-like bacteriocins, ribosomally synthesized antimicrobial peptides, are generally co-expressed with cognate immunity proteins to protect the bacteriocin-producing strain from its own bacteriocin. Bacteriocins are considered potential alternatives to conventional antibiotics in the context of the bacterial resistance crisis, but the immunity mechanism is unclear. This study uncovered the mechanisms of action and immunity of class IIa bacteriocins.

Abstract:
ThnM1 is a putative sugar- O -methyltransferase produced by the Nocardia sp. strain CS682 and is encoded by a gene belonging to the biosynthetic gene cluster (BGC) of 1-(α- l -(2- O -methyl)-6-deoxymannopyranosyloxy)-3,6,8-trimethoxynaphthalene. We demonstrated that ThnM1 is a promiscuous enzyme with regiospecific activity at the 2′-OH of rhamnose.

Abstract:
Phenazines have been widely acknowledged as a natural antibiotic for more than 150 years, but their degradation mechanisms are still not completely elucidated. Compared with the studies on the degradation mechanism of PCA and PYO, little is known regarding PCN degradation by far.

Abstract:
Most species of APMVs are understudied and/or underreported, and many species were incidentally identified from asymptomatic wild birds; however, the disease significance of APMVs in wild birds is not fully determined. The rapid rise in high-throughput sequencing coupled with avian influenza surveillance programs have identified 12 different APMV species in the last decade and have challenged the resolution of classical serological methods to identify new viral species.

Abstract:
This study aimed to compare the chromosomal beta-lactamase from Pectobacterium versatile , PEC-1, with the well-known and globally distributed TEM-1 in terms of genetic and functional properties. Despite the similarities between the enzymes, we obtained no definitive proof of gene transfer for the emergence of blaPEC-1 from blaTEM-1 .

Abstract:
Listeria monocytogenes tolerance to quaternary ammonium compounds has been raised as a concern with regard to L. monocytogenes persistence in food processing environments, including in fresh produce packing and processing environments. Persistence of L. monocytogenes can increase the risk of product contamination, food recalls, and foodborne illness outbreaks.
