Xylanase breaks xylan down to xylose, which is used in industries such as pulp and paper, food and feed, among others. The utilization of wastes for xylanase production is economical, hence this work aimed at producing xylanase through solid-state fermentation and characterizing the enzyme. Xylanase-producing strains of Bacillus megaterium and Aspe...

The synergy between enzyme and nanotechnology (Nano-biocatalysts) has greatly surfaced as one of the promising biomaterials fabricated by synergistically incorporating advanced nanobiotechnology. The incorporation of enzymes into nanotechnology is of great significance to make nanomaterials rarely harmful to the environment. However, the unique/spe...

Lignocellulosic substrates are wastes in the environment whose reducing sugars are not readily available for use. Biological pretreatment is the use of microorganisms and/or their metabolites to break down substrates to obtain simple sugars which is also cheap compared with other pretreatment techniques. This work is aimed at degrading lignocellulo...

The three major parts of lignocellulose are cellulose, hemicellulose and lignin which can be broken down by cellulase, xylanase and laccase, respectively, thereby making the reducing sugar in lignocellulose available for industrial processes. This work aimed to screen for white-rot fungi with the potential of producing cellulase, xylanase and lacca...

Bacillus species have diverse applications in agriculture, enzyme production and medicine to produce vaccines and probiotics. Currently, little is known about the probiotic potential of Bacillus from fermented condiments of African origin. This work aimed at isolating Bacillus spp. with probiotic potential from fermented African locust bean-iru. Ir...

Bioethanol production from monomeric sugar is performed by several yeasts. But there are several limitations associated with yeast strains such as their low tolerance to ethanol, toxic inhibitors, and high sugar concentration. Genetic and metabolic engineering of potential yeast strains can overcome the above limitations. The present article summar...

Maize straw is a lignocellulosic waste that is annually added to the environment as pollutant because its accumulation constitutes a nuisance and in addition, its reducing sugar is not readily released. Pretreatment of maize straw makes its reducing sugar available for fermentation into bio-products such as bioethanol production under optimized con...

Maize straw (MS) is a lignocellulosic substrate that constitutes huge wastes in the environment. This work aimed to pretreat MS with mushroom alone as a biological agent, and with NaOH prior to mushroom treatment (combined chemical and biological), and subsequently converting the released reducing sugars (RS) to ethanol using Saccharomyces cerevisi...

Aquaculture is a global practice that entails the breeding of different fish species. It is incessant in the Nigerian community as wastewater released from pond farms into surrounding drainages and water bodies cause pollution. In this study, a comparative analysis of the physico-chemical parameters (temperature, pH, salinity, conductivity, Dissolv...

Tannases are enzymes that catalyze the production of gallic acid which is a versatile precursor of various chemicals used in food and pharmaceutical industries. This work is aimed at isolation and production of tannase from soil fungi. Moulds were isolated from soil samples that were collected from different sites in Ibadan Metropolis. Isolated fun...

Introduction: Oxacillin resistant Staphylococcus aureus (ORSA) associated with beef and frozen chicken is a threat to public health because of the potential ability of them being multiple antibiotics resistant. Aim: The aim of this study is therefore to isolate, determine the susceptibility of S. aureus to oxacillin and subsequently other antibioti...

Introduction: Amylase, cellulase and protease are known for hydrolyzing starch, cellulose and protein respectively and these enzymes can be produced by microorganisms. A single bacterium with potential of producing amylase, cellulase and protease will be an organism of high industrial value. Aims: This work aimed at isolating bacteria that will be...

Peels of sweet potato (Ipomoea batatas) were buried in the soil for 14 days and the isolates associated with the degradation of the peels were obtained using standard microbiological procedures. The bacterial isolates obtained were screened for amylolytic and cellulolytic activities under different pH and temperatures as parameters and optimized fo...

Cellulase is an enzyme complex which breaks down cellulose to glucose. The need for economical, complete and fast industrial processes necessitates the use of very active starters able to operate at high temperature of production to degrade cheap nutrients most of which are cellulolytic; hence the search for thermophilic cellulolytic yeasts from th...

Lactic acid bacteria (LAB) responsible for spontaneous fermentation of cucumber were isolated and their antimicrobial producing potentials were screened against 10 indicator strains. 65% of the isolated LAB produced antimicrobial activities against at least two indicator strains. The indicator strains used were: Escherichia coli, Bacillus lichenifo...

The feasibility of bioethanol production from spontaneous fermentation of palm oil mill effluent was carried out. Cooled POME (1.5L) was allowed to ferment spontaneously for 21 days for analysis of microbial quality, free fatty acid, lipase activity and ethanol contents. Effect of pH and supplementation on ethanol and other parameters were also det...

Palm Oil Mill Effluent (POME) has great potential as a substrate for acetone, butanol and ethanol fermentation because it contains a mixture of carbohydrates including starch, hemicellulose, sucrose and other carbohydrates that can be utilized by microorganisms. Hence microorganisms were isolated from spontaneously fermenting POME, the predominant...
