TL;DR: This review was organized to address bioremediation as a practical option for the treatment of dye by evaluating its performance and typical attributes and highlights the current hurdles and future prospects for the abatement of dyes via biotechnology-based remediation techniques.

TL;DR: In this paper, the authors reported the adsorption of Cr (VI) from aqueous solutions on activated carbon prepared from mango kernel, a seasonal waste from mango fruits, pulverized in a micro-pulverizing mill.

TL;DR: The best microbial species for metabolizing dye molecules was selected amongst the isolated bacterial populations by conducting methylene blue (MB) batch degradation studies with the bacterial strains using NaCl‐yeast as a nutrient medium.

TL;DR: The experiment showed that bacteria immobilized with coconut shell biochar in continuous mode showed much better degradation than batch study without immobilization, and the kinetics parameters μmax, Ks, and μmaxKs were found to be 0.0117 L/mg/day using Monod model.

TL;DR: In this article, the kinetics of Ni (II) and Cr (VI) sorption by Microcystis, was studied in single and multimetal systems, and external mass transfer and intraparticle diffusion data suggested that MicrocyStis resembles a physical sorbent and therefore holds great potential for employment as a substitute (but requires revalidation at large scale) of physical sorbents in wastewater treatment.
