The textile industry is one of the anthropogenic activities that most consume water and pollute water bodies. Therefore, the present work aims to undertake a review on the main effects of the release of industrial dyes and the essential bioremediation mechanisms. The textile dyes significantly compromise the aesthetic quality of water bodies, increase biochemical and chemical oxygen demand (BOD and COD), impair photosynthesis, inhibit plant growth, enter the food chain, provide recalcitrance and bioaccumulation, and may promote toxicity, mutagenicity and carcinogenicity. In spite of this, the bioremediation of textile dyes, that is, the transformation or mineralization of these contaminants by the enzymatic action of plant, bacteria, extremophiles and fungi biomasses is fully possible. Another option is the adsorption. Despite some disadvantages, the bioremediation is essentially positive and can be progressively enhanced by modern biotechnological techniques that are related to the generation of more degrading and more resistant engineered organisms. This is a sustainable solution that provides a fundamental and innovative contribution to conventional physicochemical treatments. The resources of environmental biotechnology can, therefore, be used as tangible technological solutions for the treatment of textile dye effluents and are related to the ethical imperative of ensuring the minimum necessary for a quality life for the humankind.</p></div>","PeriodicalId":100187,"journal":{"name":"Biotechnology Research and Innovation","volume":"3 2","pages":"Pages 275-290"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.biori.2019.09.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79921542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Antimicrobial therapy often demonstrates failure, with low cure rates, bacterial resistance and bacterial seclusion in the outbreaks of infection as well as leaving its residues in soil, water, and even animal products. Advances in research may provide benefits to animal welfare by increasing cow's resistance to mastitis by inducing mammary gland cells to secrete an antibacterial protein called lysostaphin, which is a potent staphylocolytic enzyme. Over the years, research groups have developed projects aimed at developing particular immunomodulators, as well as transgenic lysostaphin-secreting cows. The focus of this review is to compile studies on the use of lysostaphin and in the therapeutic and prophylactic control of staphylococcal mastitis using genetic engineering and biotechnology as an alternative tool. In the transgenic models of mice and cows, lysostaphin was able to prevent staphylococcal mastitis presenting little effect on the integrity of the mammary gland, animal physiology and milk produced.
