Mechanisms of action of some probiotics

INTRODUCTION The term probiotic (opposite of antibiotics) is used when we refer to bacteria associated with beneficial effects on humans and animals. It was invented in the early twentieth century by Nobel Prize winner, Eli Metchnikoff, and introduced in his study, the prolongation of Life. (Metchnikoff, 1907).Metchnikoff has shown since 1907 that Lactobacillus bulgaricus is able to eliminate pathogenic bacteria from the intestinal microflora. The actual introduction of the concept belongs to...

THE EFFECTS OF ESTERIFICATION ON COLD WATER SOLUBILITY OF CASSAVA STARCH

ABSTRACT The aim of this study is to improve the Cold Water Solubility (CWS) and esterification activity of Native cassava Starch (NS) by pretreatment using NaOH (Sodium hydroxide) aqueous solution. The influence of pretreatment on granule shape and crystal structure of cassava starch was investigated by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). It has been found that the average particle size of Pretreatment cassava Starch (PS) decreased to nanometer level, smaller than...

ANTIBACTERIAL ACTIVITY OF HONEY ON (STAPHYLOCOCCUS AUREUSESCHERICHIA COLI AND STREPTOCOCCUS PYOGEN) ISOLATED FROM WOUND

ABSTRACT Antibacterial activity of honey obtained from two different locations in Enugu State (Nsukka & Ugwuaji) Nigeria on Staphylococcus aureus, Escherichia coli and Streptococcus pyogens isolated from wound was studied. Agar well diffusion method was used to determine the antibacterial activity of the honey on the test microorganisms. The result revealed that the two honey samples have heavy antibacterial activities against the test organisms and zones of inhibition were obtained showing h...

Polymer Degradation

ABSTRACT Polymers are used in various ways and they constitute the bulk of demand in the utilization of basic petrochemicals both in industries and domestic uses. Polymers have posed serious environmental problems because of their undegradability. Polymer degradation is a change in the properties of a polymer or polymer based products under the influence of one or more environmental factors such as heat, light, chemicals such as acids, alkalis and some salts, atmospheric oxygen, microorganism...

CORROSION BEHAVIOUR OF METALS/ALLOYS WITH AND WITHOUT COATING AT HIGH TEMPERATURE (200 – 1000OC) AND UNDER MARINE ENVIRONMENT

INTRODUCTIONCorrosion is the deterioration a material undergoes as a result of its interaction with its surroundings. Although this definition is applicable to any type of material, it is usually reserved for metallic alloys. Of the 105 known chemical elements, approximately eighty are metals , and about half of these can be alloyed with other metals, giving rise to more than 40,000 different alloys. Each of the alloys will have different physical, chemical, and mechanical properties, but all...

Roles of bacteriocins in food safety

INTRODUCTION DEFINITION AND HISTORY Bacteriocins are bacterial ribosomally synthesized peptides or proteins with antimicrobial activity. As ribosomally synthesised peptides, bacteriocins are encoded by a plasmid- or chromosome-borne structural gene which is often clustered with genes coding for immunity protein(s) and dedicated transport. Bacteriocins are proteinaceous toxins produced as a tiny molecule by bacteria to inhibit the growth of similar or closely related bacterial strain(s) produc...

DESIGN AND IMPLEMENTATION OF AUTOMATED MOTOR VEHICLE DRIVING SYSTEM

ABSTRACT This project was centered on automated motor vehicle driving licensing system. The current process of motor vehicle licensing is being operated manually and due to this procedure numerous problem are been encountered. A design was taken to computerized the manual process in order to check this problem. The problems were identified after series of interviews and examination of documents after which analysis was made and a computerized procedure recommended. This project will also sugg...
