Antimicrobial Resistance Pattern of Coagulase-negative Staphylococci isolates from Medical Students of Some Nigerian Teaching Hospitals

AbstractThe antimicrobial resistance or otherwise of Coagulase-negative Staphylococci (CoNS) isolates from medical students of some South Eastern Nigerian Universities were determined. Swab samples were obtained from the students and were cultured for CoNS using standard microbiological methods. Isolates obtained were assayed for antibiotic resistance using disc diffusion method. MecA and blaZ genes on 533bp and 510bp respectively, of the isolates were amplify using the Polymerase Chain React...

ENHANCEMENT OF METHANE PRODUCTION BY CODIGESTION OF KERATIN AND CELLULOSIC FEEDSTOCKS AT MESOPHILIC AND THERMOPHILIC CONDITIONS USING MICROBIAL CONSORTIA

ABSTRACTNigeria has energy crisis, hence, there is urgent need to diversify the country’s energy resources towards renewable alternatives for economic and social transformation. Biogas generated from the anaerobic digestion of local biomass resources, will increase national energy security as well as reduce dependence on fossil fuels. Optimization of methane production by codigestion of poultry feather and sawdust using microbial consortia were investigated. The results of the molecular ide...

ISOLATION AND CHARACTERIZATION OF MICROORGANISMS ASSOCIATED WITH BIOREMEDIATION OF HYDOCARBON POLLUTED SITES

Abstract: The negative impacts of hydrocarbon pollutants on our environments and economic resources cannot be overemphasized. The need to harness the bioremediation potentials of microorganisms associated with hydrocarbon pollution becomes very imperative in order to mitigate the environmental impacts of petroleum hydrocarbons in our environments. The molecular identification of the microorganisms isolated from four automobile workshops at Ugbene 2 Abakpa Nike, Enugu,...

PRODUCTION OF COMPOSITE YOGHURT FROM BLEND OF SOY MILK AND COW MILK USING MIXED LACTIC STARTER CULTURES ISOLATED FROM AQUARAPHA YOGHURT

ABSTRACTThe need to improve our vegetable protein consumption in order to reduce the incidence of protein deficiency diseases cannot be over-emphasized. This research was premised on evaluating the appropriate levels of substitution of cow milk with soya milk to produce composite yoghurt. Eight hundred (800) grams of soya bean seeds after sorting out foreign materials and washing were usedto produce 4.0 liters of soya milk (20% total solids). Cow milk (20% TS) was blended with soya milk in th...

Keywords: Environment, Annual rate, Global crisis, Foreign investors, Epidemiology, Psychology.IntroductionThe outbreak of Coronavirus Disease (COVID-19) has been declared...

Determination of Minimum Data Set for Vegetable Fields under Biofertilizer-fortified Compost Farming in Southwestern Nigeria

This  study  discovered  that  infiltration  rate,  bulk  density, pH  and  available  phosphorous  were  the  most  sensitive  soil properties  for  use  as  MDS  indicators for vegetable fields at south western of Nigeria. The    study    also    revealed    that    both    the  MDS indicators  and  SQI  value  obtained  were  influenced  by biofertilzer-fortified  compost  application and would  serve  as vital  instrument for evaluating soil fe...

Phytohormone Biosynthesis by Indigenous Rhizobacteria of Vegetable Crops in a Semi-arid Agro-environment

This      study      discovered      indigenous      rhizobacteria (A. brasiliense,  A. chrocoocum,  P. stutzeri  and  P. putida)  from the  rhizosphere  of  vegetable crops in semi-arid agro-zone of Rajasthan desert capable of synthesizing phytohormone. This study   will provide baseline information on the phytohormone biosynthesis    profile    of    t he    isolates    and    the phytohormone produced can be transformed into commercial bio-formulations  f...

Arbuscular Mycorrhizal Fungi Associated with Rhizosphere of Tomato Grown in Arid and Semi-arid Regions of Indian Desert

This  study  provides  knowledge  on  the  diversity  and drivers  of  AMF  in  the  ecologically  stressed  ecosystem  of  arid and  semi-arid  regions  of  Indian  desert  and  reveals  promising findings  that  would  provide  baseline  information  for  a  better understanding  of  more  important  roles  that  AMF  plays  in enhancing  resource  allocation  and  increasing  tolerance  of tomato plant to the  various  environmental  stresse...

Bio-filmed Bio-fertilizers and Organic Manure Application forReducing Chemical Fertilizer in Sustainable Okra production

The  study  justifies potentials  of  fungalbacterial  biofilm  bio-fertilizers  (FBBs)  and  organic  manure application  as  sustainable  means  of  improving  growth  and yield of okra, optimizing economics of production by reducing amount  of  chemical  fertilizer  application  and  minimizing  its deleterious  effects  on  environment,  soil  and  human  health. Appropriate  adoption  of  these  findings  by  farmers  and researchers  would  go  a...

Comparative adsorption of amylase, protease and lipase on ZnFe2O4: kinetics, isothermal and thermodynamics studies

Abstract The role of enzyme engineering in biotechnol-ogy, biological and pharmaceutical process cannot be overemphasized. This study compared the adsorption ofdigestives enzymes; amylase, protease and lipase on to Zn-ferrite (ZnFe2O4). The metal ferrite was synthesized via asol–gel technique and characterized with scanning electronmicroscopy (SEM), X-ray diffraction (XRD), Electronparamagnetic resonance (EPR) and Fourier transforminfrared spectroscopy (FTIR). The adsorption was studiedin a...

EFFECTS OF FERMENTED PALM WINE ON SOME DIARRHOEAGENIC BACTERIA

The effect of fermented palm wine tapped from Raphia palm tree (Raphia hookeri) on the growth ofsome common diarrhoeagenic bacteria such as Staphylococcus aureus, Escherichia coli,Salmonella typhi, Shigella dysentariae and Esherichia coli 0157:H7 was carried out using agardiffusion method. The palm wine used had growth inhibitory effect on all the test organisms withdiameter of zones of inhibition ranging from 2.20mm to 28.20mm. Palm wine subjected tofermentation for 168hours (7 days) exerted...

Improvement of the Physicochemical and Microbiological Quality of the Date’s Fruit Product in South Algeria by Adding Rosemary Herb

The dates are used to prepare several food products, among which the Btana is a best conservation form commonly practiced in the South-west area of Algeria. The peasants add during its preparation one or more aromatic herbs according to the choice and the areas. The present research aims relates to the study of the effectiveness of the methods used from the microbiological quality point of view and the determination of the effect of the plants added during the Btana preparations, for that...

Generation of bioethanol from common date by-products, “Teggaza and Lebghel” in Southern Algeria

Date by-products constitute the principal food for the oasis populations in Middle East and North Africa. Dates contents consist of 70 to 80% of reducing sugars, and do not require an intensive energy and labour for thermophysical pre-treatment. They can serve as a good feedstock for bioethanol generation through fermentation and distillation. Algeria is among the top sixth producers of dates in the world with more than 250,000 tons/year; from these, more than 30% can be lost for dif...

An investigation on the activities of amylase, cellulase and pectinase from Bacillus and Aspergillus species isolated from stale fast food sample
