ABSTRACT The effluent from the tanning process generates negative impacts on health and the environment because at this stage only 70% of the total chromium (Cr) used is used; whereby bioadsorption emerges as an alternative in the removal of heavy metals. In this regard, the objective of the present investigation was to evaluate the capacity of chromium removal in effluents from the tanning stage of the tannery Harold SAC tannery using as yeast sorbent of the genus Saccharomyces cerevisiae (S), Pichia guilliermondii (P) and the microbial consortium consisted of (S) + (P); These were isolated from agroindustrial waste. For the observation of yeast cells, an OLYMPUS brand binocular microscope, Mo.CX23LFS1, was used. The experimental procedure consisted of the use of 6 bioreactors of 250 ml conditioned with samples of effluent from the tanning stage, having the consortium (S + P) as sorbent...
