Harnessing a deep-sea EAL-domain enzyme for quorum quenching and biofilm control in food pipelines.

This study explores the potential of quorum-quenching (QQ) enzymes from deep-sea bacteria to disrupt bacterial communication and biofilm formation. Among 21 psychrophilic marine isolates, Vibrio sp. strain SAT06 showed broad-spectrum QQ activity by degrading both short (C-HSL) and long-chain (3-O-C-HSL) acyl homoserine lactones.

Microplastics under siege: Biofilm-forming marine bacteria from the microplastisphere and their role in plastic degradation.

Microplastics, a complex category of pollutants containing microorganisms and toxins, pose a significant threat to ecosystems, affecting both biotic and abiotic elements. The plastisphere's bacterial community differs significantly from nearby habitats, suggesting they may significantly contribute to the degradation of plastic waste in the ocean. This study evaluated the diversity of culturable bacterial populations attached to the microplastics in the coastal zones of the A&N Islands and their potential for plastic degradation.

Decoding the multifunctional potential of ursolic acid: antioxidant, antiproliferative, molecular dynamics, and biodegradability evaluations of a mangrove-derived terpenoid.

Excoecaria agallocha L, a mangrove plant widely used in traditional medication in India, was the focus of this study to evaluate its antioxidant, anticancer, structural, dynamic, and biodegradability properties of its bioactive compound, ursolic acid. This study, a sample (E. agallocha) collected from the tropical Islands ecosystem of South Andaman, India, represents the first report identifying Ursolic acid from the methanolic extract.

Seasonal dynamics of thraustochytrids in mangrove rhizospheres for microbial interactions, PUFA production.

This study investigated seasonal variations of thraustochytrids in rhizosphere soil collected from two mangrove species Rhizophora apiculata and Avicennia marina in natural and planted mangrove stands. Thraustochytrid counts were higher in the natural mangrove stand than in the planted site. The counts varied seasonally, being highest in the post-monsoon season followed by summer, monsoon, and pre-monsoon.

Anticancer efficacy of magnetite nanoparticles synthesized using aqueous extract of brown seaweed Rosenvingea intricata, South Andaman, India.

Cancer is a global issue and hence various efforts are being made. Iron oxide is considered a significant biochemical agent in the biomedical arena for cancer treatment. Marine macroalgae-mediated iron oxides especially, magnetite (FeO) nanoparticles (NPs) are a prospective alternative to diagnose and treat cancer owing to their fluorescent and magnetic properties.
