Metagenomic analysis of microbial community and its role in bioelectrokinetic remediation of tannery contaminated soil

Application of photoelectrochemical oxidation of wastewater used in the cooling tower water and its influence on microbial corrosion

“…The water sample consists of the most abundant bacterial OTU class (%) as follows ( Figure 1 ): Fusobacterium (22), Nitrospria (21), Tepidiforma (13), Bacteroides (12), Arcobacter (7), Clostridioides (6), Treponema (6), Flavobacterium (5), Bifidobacterium (4), and Hyphomicrobium (4). The water sample contains diverse microbial genera ( Figure 1 ) such as Corynebacterium, Actinomyces, Streptomyces, Collinsella, Olsenella, Eggerthella, Baekduia, Clostridioides, Streptococcus, Lactobacillus, Bacillus, Xanthobacter, Erythrobacter, Sulfuritalea, Acinetobacter, Sulfurivermis, Desulfovibrio, Desulfomicrobium, Desulfotomaculum, Geobacter, Bacteroides, Fibrobacter, Pseudorhodoplanes, Nitrospira, Fimbriimonas, Flavobacterium, Pseudomonas, Clostridium , and Staphylococcus ( Figure 1 ) (Prakash et al, 2021 ). The metabolic activates of cooling tower water in the bar graphs representing microbial community composition revealed metagenomes at taxonomic levels in the cooling tower wastewater: (a) phylum, (b) class, (c) order, (d) family, and (e) genus.…”

“…Before PCR amplification, the extracted DNA from the samples was subjected to NanoDrop and GEL Check. The NanoDrop readings of 260/280 at an approximate value of 1.8–2 are used to evaluate the quality of the DNA (Prakash et al, 2021 ).…”

“…The UV–visible spectrophotometer (UV-1800 SHIMADZU, Japan) was used to determine contaminants in the water sample both before and after treatment. APHA color measurements were quantified using the Hazen color index, and COD analysis was done at time intervals of 0, 2, 4, 6, and 8 h (Prakash et al, 2021 ).…”

1 Effects of Phosphate-rock Mining Wastewater Fertigation on Chickpea (Cicer arietinum) Cultivation and Soil Microbial Diversity

“…Worldwide, plant growth-promoting rhizobacteria (PGPR) are known to promote plant growth attributes by direct and indirect mechanisms such as the production of phytohormones (indole acetic acid (IAA), cytokinin, and gibberellic acid, P solubilization, siderophore production, and nitrogen fixation) and promote the mineral nutrient uptake (Ali and Pati 2023). PGPR are widely used for increasing sustainable agricultural productivity as well as enhancing soil fertility and health (Prakash et al 2021). In contemporary investigations, the synergistic interaction between Plant Growth-Promoting Rhizobacteria (PGPR) and mining waste has been the subject of scientific inquiry.…”

Adsorption mechanism of Cr(VI) on woody-activated carbons

“…Currently, there are numerous methods to clean up Cr(VI) contamination from wastewater, including bioremediation [ 46 ], precipitation [ 3 ], photocatalytic reduction [ 31 ]，membrane treatment [ 21 ], oxidation filtration [ 63 ], electrochemical [ 33 ] and adsorption methods [ 10 , 12 , 53 , 55 ]. However, it was found that some treatment methods were pricy, challenging, and also produced dangerous secondary contaminants [ 40 , 66 ]. Adsorption has been called the most promising and well-liked treatment strategy because of its accessibility, improved removal effectiveness, and generally straightforward operation [ 47 ].…”
