Abstract:The traditional use of beam house chemicals such as lime and sodium sulfide for hair removal from hide/skin results in significant environmental drawbacks, including excessive water consumption, hair digestion, and solid sludge discharge into effluent. In this study, we have isolated proteolytic bacteria belonging to Alcaligenaceae sp. (GenBank accession number OP456525) from the soil of a tannery solid waste dumping yard. These bacteria exhibited robust protease production with optimal activity at 50°C and pH… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
