Summary: This study identified key enzymes involved in the starch saccharification process, including glucoamylase, alpha-amylase, and acid alpha-amylase, out of 29 glycoside hydrolases from the 6-day fermentation products of A. niger O1. Synergistic effects were observed among the components of glucoamylases cocktail, with an increase in alpha-amylase leading to improved efficiency of starch saccharification. Overexpression of acid alpha-amylase in strain O1 resulted in an increase in total glucoamylase activity.

Summary: This study proposes a modified simultaneous saccharification and fermentation process for the production of bioethanol from highly concentrated raw corn starch. Factors influencing the hydrolysis of concentrated raw corn starch and the optimal conditions for the highest yield of hydrolysis were investigated. The modified process achieved a bioethanol concentration of 129.2 g/L with a productivity of 2.94 g/L/h and an ethanol yield of 87.8% theoretical yield. This work provides valuable information for bioethanol production and offers a novel strategy for raw starch hydrolysis under industrial conditions. Rating: 9/10.

Summary: The aim of this study was to characterize cold-adapted bacteria by testing their plant growth promotion (PGP) features and antagonistic activity against Macrophomina phaseolina, both in vitro and on soybean seeds. The results showed that Serratia proteamaculans 136, 137, and Burkholderia gladioli MB39 exhibited PGP features and inhibition of M. phaseolina infection by producing different antifungal compounds. These findings highlight the potential of these bacteria as candidates for developing microbial formulations to promote plant growth and provide antifungal protection in soybean crops.

Summary: Plastic pollution, particularly from PET, is a significant environmental challenge. This study investigates the enzyme kinetics of PET degradation and finds that the degree of crystallinity (X-C) has a substantial impact on the enzymatic reaction rate. The mobile amorphous fraction (X-MAF) is a better descriptor for the rate of enzymatic degradation. The longer lag phase observed with increased X-C is proposed to be due to increased substrate entanglement density and unproductive enzyme binding to the crystalline regions of PET.

Summary: Bacillus licheniformis 2709 is an important industrial producer of alkaline protease (AprE), and this study identified the UP elements of the aprE gene and demonstrated the lack of significant effect of CggR, FruR, and YhcZ transcription factors on aprE expression. Enhanced aprE expression and enzyme activity were achieved by deleting a negative regulatory factor binding site in the genome. These findings provide valuable insights into the high-level production of proteins in other Bacillus species.

Summary: A biofilm layer called biofouling is formed over time by organic molecules and microorganisms on solid surfaces immersed in a liquid medium. This study focused on the antifouling performance of polyaniline (PANI) and investigated the immobilization of hydrolytic enzymes in PANI coatings. The results showed that the alpha-amylase-containing film exhibited the highest antifouling activity. Surface properties and biofilm composition were analyzed to support these findings.
