The textile industry produces harmful effluents that are discharged into the environment, damaging the aquatic and other ecosystems. A yeast-based solution for decolorization of textile industrial wastewater was produced and evaluated. Three yeast strains, Candida parapsilosis (HOMOGS20B), Yarrowia lipolytica (HOMOGST27AB) and Candida pseudoglaebosa (LIIIS36B), isolated from a textile wastewater treatment plant and previously selected for their dye decolorization capacity, were freeze-dried.

- Dyed wastewater from the textile industry poses environmental challenges, and biotechnological methods using certain yeast strains may offer a greener solution for treatment.
- The study tested yeast strains Candida parapsilosis, Yarrowia lipolytica, and Candida pseudoglaebosa for their ability to decolorize a variety of textile dyes and found that they could effectively degrade over 50% of the dyes in 28 out of the 32 solutions tested.
- Y. lipolytica and C. pseudoglaebosa showed the highest decolorization rates, particularly with reactive dyes, and their enzymatic activity indicates their potential for use in bioremediation and sustainable water practices.
Background: Epigenetic modifications, including DNA methylation of tumor suppressor genes carried out by DNA methyltransferases (DNMTs), are important events in carcinogenesis. Although there are studies concerning to its expression in several cancer types, DNMTs expression pattern is not known in photoinduced lip carcinogenesis. The aim of this study was to investigate the immunoexpression of DNMTs 1, 3a, and 3b in lip precancerous lesion (actinic cheilitis) and cancer.
