Bioethanol production by immobilized co-culture of Saccharomyces cerevisiae and Scheffersomyces stipitis in a novel continuous 3D printing microbioreactor.

Biorefineries require low-cost production processes, low waste generation and equipment that can be used not only for a single process, but for the manufacture of several products. In this context, in this research a continuous 3D printing microbioreactor coupled to an Arduino-controlled automatic feeding system was developed for the intensification of the ethanol production process from xylose/xylulose (3:1), using a new biocatalyst containing the co-culture of Scheffersomyces stipitis and Saccharomyces cerevisiae (50/50). Initially, batch fermentations of monocultures of S.

Application of lipase from Burkholderia cepacia in the degradation of agro-industrial effluent.

This study aimed to analyze the physical and chemical characteristics of Amano PS commercial lipase - Burkholderia cepacia and lipase produced by Burkholderia cepacia strain ATCC 25416, in addition to studying the hydrolysis of agro-industrial effluent collected in a fried potato industry. The optimum temperature for increasing lipase activity was 37 °C. The temperature increase caused a decrease in thermostability of lipase, and the commercial lipase was less stable, with values of 10.
