Biotransformation of the residual liquid from the wet coffee benefit by Kluyveromyces marxianus
The search for biotechnological alternatives for the use of residuals generated in the agro-industrial processing of coffee is a current problem. This study evaluated the biotransformation of the liquid residual of the humid coffee benefit using the yeast Kluyveromyces marxianus CCEBI 2011. It was demonstrated that this strain is able to effectively use the reducing and neutral sugars in 24 h, for a yield of 40% in the...

Biosurfactant production by Bacillus subtilis UFPEDA 86 using papaya (Carica papaya L.) waste as substrate: Viability studies and pH influence of the culture medium
Biosurfactants are surface-active compounds derived from microorganisms and offer several advantages over chemical surfactants, such as low toxicity, good biodegradability and ecological acceptability. Even though interest in biosurfactants is increasing, these bioproducts do not compete economically with synthetic surfactants due to the overall costs of the bioprocess. The use of inexpensive raw materials is an...
