Assessment of metal-associated health risk in different trophic levels in tropical estuary on the southeast coast of India.

Metal contamination in coastal and marine ecosystems has become a significant global concern due to its hazardous characteristics, environmental persistence, and ability to bioaccumulate in aquatic ecosystems. This poses a serious threat to the environment and the health of humans worldwide. To address these concerns, this study estimated the concentrations of metals in various trophic levels, including phytoplankton, zooplankton, bivalve, and fish.

Bromoform Toxicity to Marine Microalgae: Studies using the Diatom Chaetoceros lorenzianus as a Model Organism.

Bromoform is the most prominent, relatively long-lived chlorination by-product in condenser effluents from seawater-based power plant cooling systems. There are few reports on the potential toxicity of this trihalomethane to marine phytoplankton. We investigated this using a marine diatom, Chaetoceros lorenzianus as the model organism.

Biodegradation of phenanthrene by piezotolerant Bacillus subtilis EB1 and genomic insights for bioremediation.

A marine strain B. subtilis EB1, isolated from Equator water, showed excellent degradation towards a wide range of hydrocarbons. Degradation studies revealed dense growth with 93 % and 83 % removal of phenanthrene within 72 h at 0.

Complete Genome Analysis of Undecylprodigiosin Pigment Biosynthesizing Marine Species Displaying Potential Bioactive Applications.

Marine species are underexplored for their pigment molecules and genes. In this study, we report the genome of the undecylprodigiosin biosynthesizing gene cluster carrying sp. strain BSE6.

Genome sequence analysis of deep sea Aspergillus sydowii BOBA1 and effect of high pressure on biodegradation of spent engine oil.

A deep-sea fungus Aspergillus sydowii BOBA1 isolated from marine sediment at a depth of 3000 m was capable of degrading spent engine (SE) oil. The response of immobilized fungi towards degradation at elevated pressure was studied in customized high pressure reactors without any deviation in simulating in situ deep-sea conditions. The growth rate of A.
