Arsenic-resistant Klebsiella oxytoca strain AT-02 was isolated from the ground water of the Multan region of Pakistan. The strain displayed high arsenite and arsenate resistance as minimal inhibitory concentration (MIC) was 600ppm and 10,000ppm respectively. The high tolerance of the isolated strain towards arsenate can be postulated due to significant increase in biofilm in response to arsenate.

Cold atmospheric plasma (CAP) has emerged as a promising technology for neutralizing microbes, including multidrug-resistant strains. This study investigates CAP's potential as an alternative to traditional antimicrobial drugs for microbial inactivation. In the era of increasing antimicrobial resistance, there is a persistent need for alternative antimicrobial strategies.

Unlabelled: Marine protists form complex communities that are shaped by environmental and biological ecosystem properties, as well as ecological interactions between organisms. While all of these factors play a role in shaping protistan communities, the specific ways in which these properties and interactions influence protistan communities remain poorly understood. Fourteen years and 9 months of eukaryotic amplicon (18S-V4 rRNA gene) data collected monthly at the San Pedro Ocean Time-series (SPOT) station were used to evaluate the impacts that environmental and biological factors, and protist-protist interactions had on protistan community composition.

This study focuses on the isolation and characterization of bacteria from Indonesian peat soil, particularly their potential to produce antibiotics against multidrug-resistant (MDR) pathogens, including Methicillin-Resistant <i>Staphylococcus aureus</i> (MRSA). <b>Materials and Methods:</b> Bacterial isolates were rejuvenated on nutrient agar and subjected to antimicrobial activity testing using the Bauer & Kirby diffusion method against MRSA.

Large-scale plastic wastes annually inevitably induce co-pollution of microplastics (MPs) and novel brominated flame retardants (NBFRs), while gaps remain concerning their effect on terrestrial function. We investigated the impact of polylactic acid (PLA) or polyethylene (PE) MPs after aging in soil-earthworm microcosms under decabromodiphenyl ethane (DBDPE) contamination. MPs altered the food (i.
