Subsequently‚ this was further traced to a rice salad. Environmental Health Officers investigating this outbreak suspected it may have been caused by Bacillus cereus (B. cereus). The presence of large numbers of B. cereus in a food is indicative

The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature (El-hilali et al.‚ 2012). The most eye catching factors that we tested for their impact on enzyme activity involved change in pH‚ temperature‚ boiling extract‚ and the effects of probing the

methanol and filtered through 0.45 µm filter. The filtrate thus obtained constituted the test sample. In the third method (Method 3)[13]‚ 20 g of freeze dried material was extracted using 200 ml methanol in a cold room (10°) overnight and the homogenate was centrifuged at 1252 × g for 5 min. The methanolic extract was evaporated to dryness and then the residues redissolved in 50 ml water. The aqueous extract was then centrifuged at 7826 × g for 5 min. The supernatant was first partitioned twice

hours and then placed in nutrient agar covered with Staphylococcus epidermis (gram positive) bacteria for 24 hours (in an incubator)‚ garlic will have the strongest antimicrobial effect. This is because of allicin (an active principle of garlic homogenates)‚ which has a chemical reaction with thiol groups of enzymes in the bacteria. Ginger will have the least antimicrobial effect. This is because there are not as many chemical reactions with enzymes in the bacteria. Risks: The risks of using Staphylococcus
