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...
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...
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...
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...
DERMATOPHYTE are unique of fungi that effect the Keratinous tissues of lower animals and human Dermatophytoses is the medical term for fungal infection of the superficial layer of the skin, nail, hair and scalp. The prevalence study Dermatophytoses in Wuntin Dada Primary School Bauchi is to determine the prevalence of the diseases, the different clinical types and actual species responsible for the infections. Out of 950 pupils examined, 105 children were found to be with suspected Dermat...
Psychrophilic enzymes are biocatalysts that control biochemical processes at low temperatures by either accelerating or decreasing the reaction rate. These enzymes are mainly obtained from microorganisms which inhabit cold environments and proliferate at low temperatures. The cold-loving organisms referred to as psychrophiles are adapted to the extreme cold conditions which resulted in changes in their biochemical machineries such as their enzymes. This resulted in certain characteristics of ...
Oryza sativa husks and peels of Musa paradisiaca were pretreated by hydrothermal and acid fermentation using cassava mill effluent, and co-digested in a laboratory scale reactor maintained at 45 ± 2 ⁰C for 42 days. Five digesters were used for the experiment and each digester contained equal proportion of Oryza sativa husks and Musa paradisiaca in the ratio of 1:1; and cow dung (the inoculum) was added across. Substrate in Digester X (Control) was not pretreated. Digester A contained Oryza...
Abstract The role of enzyme engineering in biotechnol- ogy, biological and pharmaceutical process cannot be over emphasized. This study compared the adsorption of digestives enzymes; amylase, protease and lipase on to Zn- ferrite (ZnFe2O4). The metal ferrite was synthesized via a sol–gel technique and characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron paramagnetic resonance (EPR) and Fourier transform infrared spectroscopy (FTIR). The adsorption was stu...
Abstract Forensic Mycology is the application of Mycology for producing evidence in terms of criminal investigation and their further evaluation in the court of law. The problem with relative neglect of Mycology in Forensic science is currently leading to insufficient knowledge, in order to support the needs for fungal expertise in areas of criminal investigation. Mucor hiemalis and Penicillium griseofulvum had been used to determine the minimum interval since death, Coprinus comatus, Hebelom...
ABSTRACT Semi- solid raw Lima beans (Phaseolus lunatus) were fermented for a period of ten days, chemical (proximate composition, antinutritional contents, pH, and total titratable acidity) and physical changes (temperature, odour, and texture) occurring during the fermentation of the lima beans were monitored. The fermentation was carried out for 48, 96, 120, 168 and 192 hours respectively at ambient temperature. The microbial load was as well monitored. Microorganisms isolated from the sam...
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...
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...
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...
Summary So far, majority of the preventive effect of prebiotics has been on animal models. However, several in vitro studies using 2D and 3D cell cultures mimicking the environmental condition as well as various organisms present within the gut of man had shown the efficacy of prebiotics in reducing the attachment of enteropathogenic organisms like S. typhi to the gut epithelium. In vivo studies with human have been able to prove its efficacy in preventing diseases such as Inflammatory bowel ...
ABSTRACT Antibiotic resistance has become a wide spread problem. The efficacy of two solvent extracts of Cymbopogon citratus against some test bacteria and fungi was evaluated. The test bacteria was; Staphylococcus aureus, and the test fungi was; Candida albicans. The phytochemical properties and the antimicrobial potency of Cymbopogon citratus (lemon grass) against selected microbial pathogens using chloroform and methanol as extracting solvents were assessed. The minimum inhibitory, bacteri...
