Summary: Phytic acid is an anti-nutritional compound that can chelate proteins and ions. Phytases are enzymes that catalyze the degradation of phytic acid and are used in industrial processes. After screening 21 yeast species, it was found that phytases from Cyberlindnera jadinii, Kluyveromyces marxianus, and Torulaspora delbrueckeii showed promising activities with tolerance to high temperature and acidic pH. This suggests that these enzymes could be effectively utilized in feed and food-related industries.

Summary: This study investigated the simultaneous production of electricity and bioremediation of sulfadiazine in wastewater using microbial fuel cells (MFCs) and an open circuit system. Results showed that MFCs had high removal efficiency of sulfadiazine and COD, as well as significant impact on the reduction of total phosphorus content in wastewater. However, at higher antibiotic concentrations, reduced microbial activity may lead to inadequate degradation of antibiotics.

Summary: The increasing demand for energy resources due to population growth and industrialization has led to the exploration of alternative renewable fuels, with bio-ethanol produced from lignocellulosic biomass being the most popular. However, challenges such as inducible enzyme secretion by fungi and the complicated structure of biomass hinder the efficient production of ethanol. This article discusses the challenges and possible solutions for cellulase action on cellulosic biomass at a high solid loading, highlighting the need for biomass pretreatment to enhance enzyme efficiency.
