Aims To evaluate hexavalent chromium (Cr (VI)) reduction potential of indigenous isolate M5, under growing and nongrowing conditions. Methods and Results Microbacterium sp. M5 was isolated from soil samples collected from a common effluent treatment plant, after enrichment of indigenous microbial diversity in the presence of 200 mg l−1 of Cr (VI). The isolate achieved complete reduction of 400 mg l−1 Cr (VI) supplement to Luria Bertani medium having initial pH of 9·0 after 48 h incubation. Furthermore, the reduction potential of resting and surfactant treated cell membrane compromised cells of M5 was evaluated. The control and biosurfactant treated cells achieved 22·71 ± 0·5% and 40·56 ± 0·5% reduction of 50 mg l−1 Cr (VI) in Tris‐HCl buffer, under resting cells conditions. To the best of our knowledge, this is the first report where cells with compromised cell membrane obtained after exposure to biosurfactant have been evaluated for Cr (VI) reduction. Conclusion The Cr (VI) reduction potential of Microbacterium sp. M5 could be effectively exploited for treatment of chromium‐rich effluents, under nongrowing conditions. Significance and Impact of the Study The isolate M5 could be a potential inoculum for effluent treatment plants as it is able to support Cr (VI) reduction under wide range of pH, salinity and in the presence of different metal ions.

Cobalt-nanoferrite as a magnetic separable material has drawn the attention of researchers due to its unique properties, significant applications and high potentiality in wastewater treatment. In this study, the cobalt nanoferrite was synthesized by chemical co-precipitation method at different annealing temperatures and characterized by X-ray diffraction, scanning electronic microscopy, energy dispersive X-ray, Fourier transform infrared spectroscopy and UV-visible spectroscopy. Then the synthesized nanoferrite was assessed and used for the treatment of tannery wastewater. The characterizations confirmed the formation of nanoferrites with size between 15 and 23 nm. The average particle size increased with increase of annealing temperatures. Typical values for tannery wastewater treatment efficiency for chromium, total dissolved solids, biochemical oxygen demand and chemical oxygen demand were 23.75, 90.83, 52.72 and 48.07% respectively. Thus, the treatment by nanoferrites appears a promising and effective method for the removal of contaminants.

“…However, it is also a major source of environmental pollution due to the discharge of huge volume of potentially toxic and hazardous wastewater into the receiving water body, which negatively affect societies (Dixit et al, 2015;Montalvão et al, 2017;Chowdhary et al, 2018). The wastewater discharged from leather industries are characterized by high pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total dissolved solids (TDS), chromium, sulfate, phosphate, chloride and highly toxic organic pollutants that makes the wastewater unfit for irrigation and poses serious damage to plants and human being (Kumari et al, 2016;Bharagava and Mishra, 2018). In India, there are more than 2500 tanneries, of these, nearly 80% are based on chrome tanning process which account for 15% of the total worldwide leather production (Shukla et al, 2009;Chandra et al, 2011).…”

“…The continuous discharge of the tannery wastewater into the environment is of serious eco-toxicological concerns (Matsumoto et al, 2006;Bharagava and Mishra, 2018). The chemicals used in tannery for the tanning process include synthetic organic pollutants like tannins, pthalates, phenolic compounds, azo dyes, surface-active compounds, pesticides, sulphonated oils and grease that are not completely degraded through secondary CETP and are released untreated.…”
