As a bioremediation technique for chromium (VI), there is the use of biomass in various forms, such as using municipal dried sludge as a permeable bio reactive barrier (Kholisa et al., 2022); also, with the use of Pseudomonas putida bacterium, which have already been evaluated with very promising results for the treatment of domestic wastewater, they have also been used for the treatment of wastewater contaminated with Cr (VI) with an efficiency of 98.6% in 26 days (Mendoza-Vela et al., 2022).	cache/cet-15322.pdf	txt/cet-15322.txt
