AbstractFermented food and beverages have potential novel Probiotic microorganism which possess many beneficial role in human health and hygiene. The tribal people consume variety of locally produced fermented food and beverages regularly and hence their gut microflora are strongly benefited. Mayurbhanj district in Odisha, India is diversified with many tribal population.

Abstract Cadmium (Cd) is a metal widely known to cause toxic effects on the environment and human health. Soil represents a rich habitat for fungi, which have certain characteristics in their cell wall that made them a powerful tool for biosorption of toxic metals. Therefore, it was sought to identify potential filamentous fungi for different methods of remediation of contaminated areas. The identification of fungi from agricultural cultivation areas that can tolerate Cd and help in cadmium remediation processes occurred through the isolation and culture of several microorganisms submitted to screening experiments and tolerance evaluation. Four strains of the genera Fusarium sp., Penicillium sp., and Aspergillus sp. were isolated. Those strains showed abilities to tolerate the stress caused by Cd, presenting a tolerance index (Ti) of 13.79 − 107.30%. Analyses of FTIR demonstrated the existence of different functional groups in the cell wall that can be involved in the coordination of Cd2+ ions, as C = O stretches of carboxyl and amide-I. Results showed a Cd uptake range of 0.88 − 3.61 mg Cd g−1 of dry biomass. The results indicated that Fusarium sp. and Penicillium sp. isolated from agricultural sites are highly tolerant to Cd and are promising fungi for implementation in remediation processes.

Abstract Waste lubricant oil (WLO) is a critical environmental issue because of its recycle and disposal challenges. A potent biosurfactant-producing bacterial strain was isolated by the enrichment culture technique using WLO as the sole carbon source from the oil-contaminated soils. The strain was identified as Achromobacter xylosoxidans (NCBI GenBank accession number: MW673656) based on the morphological, biochemical, and 16S rRNA gene sequencing. The preliminary characterization of the produced biosurfactant by biochemical methods revealed its glycolipid nature. The strain possessed extensive biodegradative potential and degraded various components present in WLO. The gas chromatography-mass spectrometry (GC-MS) analysis showed that the strain could degrade hydrocarbons (C7-C22) and diethyl phthalate, a priority pollutant, with a relative degradation of 43.87% within 7 days of incubation. The biodegradation of WLO by the strain confers its use in the bioremediation of oil-polluted environments, and the simultaneous biosurfactant production is undoubtedly a step toward greener technology.

Abstract Nickel is a valuable metal that is becoming more prevalent in the industry. Column bioleaching was used in this study to extract nickel from magnesium-bearing sulfide minerals. Two different sulfidic samples with different nickel and magnesium content were utilized to investigate the performance of column bioleaching. It was discovered that mesophilic cultures’ adaptation is delayed by increasing magnesium contents. Bioleaching outperformed leaching in terms of recovery by 80% compared to 50% in sample 1 and 70% compared to 40% in sample 2. Jarosite is precipitated in samples with a high magnesium content due to the high pH and oxidation level, which lowers bioleaching effectiveness. The pretreatment method using acid washing before the start of bioleaching treatment can reduce the amount of magnesium in samples, which increases the Ni recovery in both samples. SEM analysis was performed on each bioleaching residue. The result showed that high amounts of magnesium in the second sample could be a factor in the precipitation of jarosite. Finally, it can be concluded that the pretreatment method is a feasible Bio-heap operation. RESEARCH HIGHLIGHTS Column bioleaching of nickel was tested by mix mesophile culture in two different samples. Bacteria were found to be less adaptable to magnesium-rich minerals. More than 95% of nickel was extracted from both samples. Acid washing was identified as the best pretreatment method for each sample. Graphical abstract

Abstract Phosphorus is one of the essential elements limiting vegetative production in the world. Although phosphorus is abundant in soils, a tiny part is available for plants. With phosphate solubilizing bacteria (PSB), phosphorus, insoluble in soils, is transformed into a suitable form for plants. This study aimed to determine tricalcium phosphate (TCP) activities and rock phosphate (RP) used to isolate PSMs. 118 bacterial isolates, which can phosphate solubilizing, were incubated for 72 h in National Botanical Research Institute phosphate (NBRIP) medium using TCP and RP as phosphate sources. At the end of the incubation, the amount of inorganic phosphorus (Pi) in the medium and the pH of the medium was determined. As a result of bacterial incubation, an average of 57.87 mg L−1 Pi was detected in rock phosphate medium, while this rate was found to be 421 mg L−1 in TCP medium. After 72 h of incubation, it was determined that the pH of the NBRIP media varied between 3.60 and 5.05, and TCP dissolved seven times more to rock phosphate. This study has shown that TCP alone in determining the isolation and effectiveness of PSMs is not indigenous.
