Article Synopsis
- Dye wastewater pollution, particularly from aniline blue, is a significant environmental issue due to its toxic properties and difficulty in treatment.
- This study investigates the enzyme SDRz found in strain CT1, which effectively degrades aniline blue through specific enzymatic mechanisms and degradation pathways.
- Functional tests showed that SDRz is essential for this degradation, with the enzyme demonstrating substantial activity and efficiency in breaking down aniline blue into less harmful metabolites.
Article Synopsis
- Microalgae, particularly Chlorella vulgaris, are being studied as health-boosting feed additives in aquaculture, specifically for Atlantic salmon, due to their ability to enhance immune function and manage stress responses.
- In the study, salmon were fed diets with varying levels of C. vulgaris and showed improved feed conversion and protein retention, with notable changes in gut microbial diversity and composition after feeding on higher amounts of the algae.
- Exposure to a stressor (peracetic acid) revealed that fish on higher algae diets exhibited less transcriptional stress response and increased antioxidant protein levels, suggesting that C. vulgaris may help mitigate stress effects in aquatic species.
Seas worldwide are threatened by an emerging source of pollution as millions of tons of warfare materials were dumped after the World Wars. As their metal shells are progressively corroding, energetic compounds (EC) leak out and distribute in the marine environment. EC are taken up by aquatic organisms and pose a threat to both the marine ecosphere and the human seafood consumer because of their toxicity and potential carcinogenicity.

In addition to its potential carcinogenicity and mutagenicity in humans, recent reports have highlighted TNT toxicities in diverse organisms due to its occurrence in the environment. These toxic effects have been linked to the intracellular metabolism of TNT, which is generally characterised by redox cycling and the generation of noxious reactive molecules.

Among the four natural polycyclic aromatic hydrocarbons (PAHs) degrading strains, Comamonas testosterone (CT1) was selected as the strain with the highest degradation efficiency. In the present study, prokaryotic transcriptome analysis of CT1 revealed an increase in a gene that encodes tryptophane-2,3-dioxygenase (T23D) in the anthracene and erythromycin groups compared to CK.
