The presence of toxic pollutants such as nuclear wastes, heavy metals, pesticides, and hydrocarbons has been languishing the environment as well as the human health. Bioremediation using microbial communities is emerging as an incredible, eco-friendly, and cost-effective approach to ameliorate the adverse effects of toxic pollutants. Microbes possess astonishing metabolic capabilities to alter most forms of organic material and can survive in extreme environmental conditions which make them attractive candidate for the bioremediation. Microbes are the treasure houses for environmental cleaning and recovering of contaminated soil and they have been reported from diverse environmental conditions including hot, cold, drought, and saline. Different groups of bioremediating microbes have reported from diverse conditions, that is, bacteria, fungi including yeast, and algae. Microbes belonging to genera Alcaligenes, Aspergillus, Bacillus, Flavobacterium, Ganoderma, Methosinus, Nocardia, Phormidium, Pseudomonas , Rhizopus , Rhodococcus, and Stereum have been reported as potential and efficient bioremediators for the degradation of different pollutants of the environment such as xenobiotics, heavy metals, hydrocarbons, and paper and pulp effluent. The present review focuses on microbial diversity in bioremediation, techniques applied in bioremediation, bioremediation of different environmental pollutants, and how bioremediation processes could be monitored.","PeriodicalId":423079,"journal":{"name":"Journal of Applied Biology & Biotechnology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114551056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While previous studies focused extensively on marine systems, the increasing toxicity of MPs in agricultural cultivated soils and the aspects of MPs being accumulated causing bio-toxification are being looked upon presently. They potentially damage the yield of crop plants making their roots unable to uptake water and nutrients from the soil by accumulating near the roots. MPs have already invaded the terrestrial food chain and they have been detected in excreta of livestock animals along with earthworms and crop plants. MPs are abundant in farm soil that has interacted with sewage-sludge, plastic mulching sheets, organic fertilizers, and vermicompost for a long duration.

In this study, the analysis of both raw and treated tannery effluents (TEs) revealed the maximum reduction of chromium (91%), followed by chemical oxygen demand (COD) (76.7%), total dissolved solids (TDSs) (43.3%), oil and grease (37.2%), and biological oxygen demand (BOD) (33.3%) after common effluent treatment plant (CETP) treatment. Further, the concentration of TDS (13,317 ± 2.7 mg/l), BOD (280 ± 4.47 mg/l), COD (409 ± 2.4 mg/l), sulfate (3773 ± 7.3 mg/l), nitrate (734.86 ± 0.4 mg/l), chloride (8053.59 ± 18.7 mg/l), and chromium (7.153 ± 0.02 mg/l) in treated TE was 6.3-, 9.3-, 1.6-, 3.8-, 73.4-, 13.4-, and 3.6-fold higher than the permissible limit fixed by Central Pollution Control Board.

Phytotoxicity investigation of TE on fenugreek ( Trigonella foenum-graecum L.) and mung bean ( Vigna radiata L.) seeds germination shows that both raw and CETP-treated TEs were inhibitory for seed germination and plant growth. Further, treated TE inhibited seed germination (30%), root length (97.3%), and shoot length (88.7%) in T. foenum-graecum and at 50% concentration, respectively. However, CETP-treated TE was less toxic than the raw TE. Further, fenugreek seeds were more sensitive to TE, as they could not be germinated in both undiluted raw and treated TEs.

This work was aimed at investigating the dye decolorization potential of a mixed microbial culture (MMC) obtained from different soil and sludge samples. A single dye (Direct Blue 53) was used for comparison studies. The MMC were incubated for 9 days in mineral salt medium with dye and the absorbance of its filtrate at 647 nm (Blue dye) and 308 nm (Industrial dye) was noted down for every 22 h.

The present study explored the use of the limitedly studied, tropical Rhodococcus pyridinivorans for the decolorization of crystal violet, a typically encountered dye in the textile industry. The effect of agitation speed, temperature, pH, nutritional source, initial dye concentration, and size of inoculum on crystal violet removal were evaluated using one-factor-at-a-time method. Decolorization of 0.6 mM crystal violet carried out at agitated mode showed 73 ± 3% crystal violet removal efficiency in comparison to static mode (43 ± 2%) after 24 h. This crystal violet removal efficiency escalated to 91 ± 2% after optimizing the culture conditions at 45°C and pH 7 using maltose as carbon source and 12% (v/v) size of inoculum. Furthermore, the optimization process reduced the incubation time to achieve almost complete decolorization by 67%. Ultraviolet–visible analysis revealed that the decolorization of crystal violet primarily occurred through biodegradation. The findings from this study validated the potential of R. pyridinivorans as an effective biocatalyst to remediate crystal violet.

Dyeing effluents have emerged as a significant cause of water contamination. Dyes influence all living forms, included humans, due to their xenobiotic characteristics and toxicity, as a result, hazardous dyes from colored wastewater must be treated and removed before they are released into the ecosystem. Bioremediation is an innovative, cost-effective, and eco-friendly achievement of biotechnological novelty. Thirty dye-decolorizing indigenous strains were isolated from industrial wastewater in the present investigation from the Kashipur paper industry and SIDCUL industrial area Haridwar using nutrient broth medium amended with 100 mg/l methyl red (MR). Isolation of MR decolorizing bacteria was done by the serial dilution method followed by the spread plate method. A total of 30 isolates were isolated and subjected to primary screening which was done through the tube method. Following a primary screening, 10 potent strains were retained for further evaluation of the efficacy of color removal, designated as MRD2, MRD3, MRD4, MRD15, MRD17, MRD18, MRD19, MRD20, MRD22, and MRD28, which were presumably grouped into 10 genera according to morphology and biochemical assay. The bacterial strain MRD17 outperformed other tested strains via a decolorization assay with 74.28% degradation and decolorization of MR in 72 hours, which was further, identified as Enterobacter asburiae strain JCM6051 by 16S rRNA sequencing and submitted to the NCBI GenBank with accession number MT539179. In addition, the thermodynamic stability of the strain’s 16S rRNA sequence was investigated using bioinformatics tools such as mfold and NEB cutter.

Therefore, this study intended to treat obesity-induced Fe overload with methanolic extract of goldenberry (GB) fruit with husk on obese rats. Overall, obese rats fed the GB extract showed lower levels of cholesterol, triacylglycerol, total low-density lipoprotein cholesterol, and higher levels of high-density lipoprotein cholesterol than obese rats, along with an improvement in anthropometric characteristics of obese rats. In addition, GB supplementation improved all parameters of Fe status in blood plasma and the trace elements homeostasis in adipose tissues, proving that the GB has a substantial ferric reducing property. GB enhanced the increase in hepcidin concentration in blood plasma and hepcidin gene expression in adipose tissues.
