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.

Hypoadiponectinemia is associated with blood pressure increase in obese insulin-resistant individuals.

Adiponectin is a major adipocytokine and has been considered as an independent risk factor for arterial hypertension. Most studies on the subject have been restricted to biracial (white-black) and Asian groups. The present report examined whether adiponectin affects blood pressure in a sample of untreated obese Brazilians of multiethnic origin.
