The release of high volumes untreated effluents containing different forms chromium into waterbodies and further use this wastewater for ferti-irrigation purposes pose a direct threat to health human populations consuming produces from such agricultural fields. higher concentration above permissible limits at these sites may harm flora fauna. conventional processes used treatment chromium-containing have low efficiency, operational costs, produce toxic sludge requiring safe disposal. In contrast, the approaches exploiting living systems, as microbes/microbial products microbes, provide sustainable options. emerging advanced/novel technologies based on harnessing metabolic potential microbiome polluted achieve efficient removal heavy metals sites. success protocols developed tested lab scale needs be replicated pilot/industrial handle with varying levels organic co-contaminants harsh physiological conditions. presented chapter provides an overview impact ecosystem various advanced aspect management prevent harmful effects environment.

Comprehensive analysis of codon bias in 13 Ganoderma mitochondrial genomes

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: May 4, 2023

Codon usage bias is a prevalent phenomenon observed across various species and genes. However, the specific attributes of codon in mitochondrial genome Ganoderma remain unknown.In this study, we investigated 12 core protein-coding genes (PCGs) 9 species, including 13 strains.The codons all strains showed preference for ending A/T. Additionally, correlations between base composition adaptation index (CAI), (CBI) frequency optimal (FOP) were identified, demonstrating impact on bias. Various indicators found to vary or within strains, GC3s, CAI, CBI, FOP. The results also revealed that PCGs have an average effective number (ENC) lower than 35, indicating strong toward certain codons. Evidence from neutrality plot PR2-bias analysis indicates natural selection major factor affecting Ganoderma. 11 22 (ΔRSCU>0.08 RSCU>1) identified with GCA, AUC, UUC being most widely used By analyzing combined sequences relative synonymous (RSCU) values, genetic relationships determined, variations them. Nevertheless, RSCU-based illustrated intra- interspecies species.This study deepens our insight into characteristics, genetics, evolution important fungal group.

Hormones and the antioxidant transduction pathway and gene expression, mediated by Serratia marcescens DB1, lessen the lethality of heavy metals (As, Ni, and Cr) in Oryza sativa L.

Ecotoxicology and Environmental Safety, Journal Year: 2023, Volume and Issue: 263, P. 115377 - 115377

Microorganisms have recently gained recognition as efficient biological tool for reducing heavy metal toxicity in crops. In this experiment, we isolated a potent (As, Ni, and Cr) resistant rhizobacterium Serratia marcescens DB1 detected its plant growth promoting traits such phosphate solubilization, gibberellin synthesis, organic acid production amino regulation. Based on these findings, was further investigated application rice var. Hwayeongbyeo subjected to 1 mM As, 4 Cr stress. The plants treated with Ni appeared healthy but were lethal, indicating unfitness consumption due toxic deposition, whereas the > As instantaneously died. Our results showed that inoculation significantly decreased accumulation shoots. Particularly, uptake dropped by 16.55% 22.12% (Cr + DB1) DB1), respectively, 48.90% 35.82% (As 7.95% 19.56% (Ni respectively. These findings validated gene expression analysis results, which of OsPCS1 (a phytochelatin synthase gene), OsMTP1 transporting OsMTP5 expulsion excess metal). Moreover, considerably enhanced morphological through modulation endogenous phytohormones (abscisic acid, salicylic jasmonic acid) essential elements K P. indicate is an effective biofertilizer can mitigate
