procedure 29‚ “pH and Microbial Growth” in Benson’s Microbiological Applications: Laboratory Manual in General Biology‚ 12th edition. My group was assigned the microorganism Staphylococcus simulans. Conclusion: The plotted data defines Staphylococcus simulans’ optimum pH level to be 8.0. Based on this‚ I conclude that Staphylococcus simulans is a neutrophile growing best near a neutral pH level. From the results of groups EC-1 and EC-2‚ Escherichia Coli is a alkaliphile. However‚ based on the fact

!!!Why Use Donor Breast Milk? There are times when a mother does not or cannot breastfeed her baby as in the case of separation‚ illness‚ death of the mother‚ the mother has a low breast milk supply‚ or simply the mother chooses not to breastfeed but wants her baby to have the benefits that come from breast milk. Hospitals that care for premature infants will use donor breast milk because of the additional nutrients in breast milk that provide antibodies and protection again disease as well as the

to identify the anti-bacterial property of Ashitaba non-polar extract against gram positive organism‚ Staphylococcus aureus. There were six disk namely the different concentrations of Ashitaba extract (12.5 %‚ 25%‚ 50%‚ 100%)‚ the positive control ( Penicillin) and the negative control ( distilled water).

Why is it important not to incubate the fermentation tubes beyond 24 hours? You may not get accurate results.

Following inoculation of red soils isolated from geographically separate areas of Jordan‚ Micrococcus luteus and Staphylococcus aureus were rapidly killed. Over the 3-week incubation period‚ the number of specific types of antibiotic-producing bacteria increased‚ and high antimicrobial activity (MIC‚ ∼10 μg/ml) was observed in methanol extracts of the inoculated red soils
