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...

Prebiotics-a viable prophylaxis against Salmonella typhii

SummarySo 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 b...

Evaluation of the phytochemical composition and antimicrobial activity of lemongrass (Cymbopogon citratus) against some human pathogenic microorganisms

ABSTRACTAntibiotic 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, bacteric...

Hepatitis B infection

INTRODUCTION        Hepatitis B is a viral disease process caused by the Hepatitis B virus (HBV). Hepatitis B virus is a major cause of acute and chronic hepatitis worldwide and is more prevalence in developing countries. More than 2 billion people are infected with HBV worldwide while some 280million are chronic carriers, harbouring the virus in their liver. The disease is responsible for 80% of all cases of primary liver cases, which is one of leadin...

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

Abstract:An investigation on the activities of amylase, cellulase and pectinase from Bacillus and Aspergillus species isolated from stale fast food samples was carried out. The freshly prepared samples were of Mince pie, Scotch egg, Doughnuts, Sausages and Fishrolls obtained from fast food centres in Ikeja, Lagos, Nigeria. The Bacillus isolates were identified as Bacillus subtills, Bacillus pumilus, Bacilus licheniformis, Bacillus polymyxa and Bacillus brevis. All the isolated bacilli stra...

Bacteriological analysis of flooded soil in Benin areas, Edo State

ABSTRACT Microorganisms are important components in the structure and function of organic matter in soil, hence this work was done to identify bacterial communities present in flooded soil. Soil samples were collected from eight different areas within Benin metropolis, Edo State, Nigeria. The samples were cultured on using pour plate method, identification of the main bacterial groups was carried out based on cultural, morphology and biochemical test. The results obtained showed the to...

Socioeconomic determinants of infants mortality rate in Zaria LGA of Kaduna Nigeria

Socioeconomic determinants of infants mortality rate in Zaria LGA of KadunaABSTRACT Infant mortality remains high in Zaria Local Government and beyond despite the various policies that have been implemented by the authorities to reduce it. Although studies have examined various factors that explain infant mortality, effects of infant mortality and causes of infant mortality has been rarely explored. The study finds out socio-demographic strength of the respondents, causes of infant mo...

Review on Role of Phosphate Solubilizing Microorganisms in Sustainable Agriculture

Most of soil microorganisms are known for their ability to solubilize insoluble phosphorous compounds for releasing soluble phosphate to make phosphorous available for plant absorption. Releasement of this soluble phosphorous is very important in increasing plant growth and plant product yields. Inoculating plant seeds with phosphate solubilizing microorganisms is very effective and environmentally useful to decrease the side effect of chemical fertilizers on soil microbes and other org...

Physicochemicls and microbial quality of local fermented milk

ABSTRACTCulturally, consumption of local fermented skimmed milk (nono/tsala) is common in Northern Nigeria and many other parts of Africa and it is sometimes associated with microbial diseases due to poor hygienic practice. Hence, this study was conducted with the objectives of assessing the microbial quality and some physicochemical parameters, a purposive sampling was used to collect a total of 12 different samples from Dutse local government, Jigawa state. The results obtained showed that ...

PLASMID PROFILING OF MULTIDRUG RESISTANCE CLINICAL ISOLATES OF (Pseudomonas aeruginosa)

ABSTRACT The emergence of multiple antibiotic resistance in bacteria and the indiscriminate use of antibiotics contribute to the dissemination of resistant pathogens in the environment which may cause problems in therapy and is a serious public health issue. This study was conducted to determine the incidence of Pseudomonas aeruginosa in clinical samples and their antibiotics resistant pattern. The organisms were isolated using standard microbiological techniques and the ant...

Review on Phosphate Solubilizing Fungi

Phosphorus (P) is the second important nutrient after nitrogen. In plants, phosphorous increases the strength of cereal straw, promotes flower formation and fruit production, stimulates root development and essential for seed formation. Mobility of phosphate ions in the soil is very low due to their high retention in soil. In this regard, P supply through biological systems is considered a viable alternative, and inoculation of Phosphate solubilizing microorganisms, especially fungi to soil, ...

Review on Microbial Production of Organic Acid

The first individual process for citric acid production was the liquid surface culture (LSC), which was introduced in 1919 by Société des Produits Organiques in Belgium, and in 1923 by Chas Pfizer & Co. in US. After that, other methods of fermentation, such as submerged fermentation were developed. Although this technique is more sophisticated, surface method required less effort in operation and installation and energy cost. Organic acids such as citric, malic and pyruvic are used e...

Review on Biodegradation of Organic Compounds and Plastics

Biodegradation is defined as the biologically catalyzed reduction in complexity of chemical compounds. Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms. When biodegradation is complete, the process is called "mineralization". However, in most cases the term biodegradation is generally used to describe almost any biologically mediated change in a substrate. So, understanding the process of biodegradati...
