Saccharification and co-fermentation of lignocellulosic biomass by a cockroach-gut bacterial symbiont and yeast cocktail for bioethanol production.

Background: The eco-friendly transformation of agro-industrial wastes through microbial bioconversion could address sustainability challenges in line with the United Nations' Sustainable Development Goals. The bulk of agro-industrial waste consists of lignocellulosic materials with fermentable sugars, predominantly cellulose and hemicellulose. A number of pretreatment options have been employed for material saccharification toward successful fermentation into second-generation bioethanol.

Statistical versus neural network-embedded swarm intelligence optimization of a metallo-neutral-protease production: activity kinetics and food industry applications.

An integrated approach involving response surface methodology (RSM) and artificial neural network-ant-colony hybrid optimization (ANN-ACO) was adopted to develop a bioprocess medium to increase the yield of neutral protease under submerged fermentation conditions. The ANN-ACO model was comparatively superior (predicted = 98.5%, mean squared error [MSE] = 0.

Production, characterization, and bio-ethanologenic potential of a novel tripartite raw starch-digesting amylase from UCCM 00132.

The biological conversion of agro-waste biomass into value-added metabolites is one of the trendy biotechnological research areas in recent times. One of the major drawbacks of the bioprocess is the saccharification potential of the amylolytic enzyme that releases reducing sugar from complex biomass to serve as substrate for fermentation. The present study reports the production of a novel tripartite raw starch-digesting amylase (RSDA) by an indigenous strain with α-, β-, and gluco-amylolytic activities and its potential for bioethanol production.

Studies on plasmids of multidrug resistant uropathogens isolated from patients with urinary tract infection in a tertiary hospital in Calabar, Nigeria.

Background: Urinary tract Infections caused by multidrug resistant uropathogens have become a significant global public health problem with Nigeria being no exception.

Objective: This study is aimed at profiling and curing the plasmids of selected multidrug resistant uropathogens isolated from patients with urinary tract infection in a tertiary hospital in Calabar, Nigeria.

Methodology: Isolates were obtained from urine samples of patients using standard microbiological techniques.

Strain improvement, artificial intelligence optimization, and sensitivity analysis of asparaginase-mediated acrylamide reduction in sweet potato chips.

Unlabelled: In recent times, L-asparaginase has emerged as a potential anti-carcinogen through hydrolysis of L-asparagine in the blood for anti-leukemic application, and in carbohydrate-based foods, for acrylamide reduction applications. In this study, strain UCCM 00124 produced an L-asparaginase with a baseline acrylamide reduction potential of 64.5% in sweet potato chips.
