appearance was observed and recorded. There was growth that appeared pinkish in color. The first test we did was basic stain using a heat fixed emulsion which kills the bacteria and allows them to adhere to the slide and thickens their protein for better staining. I then covered the heat fixed emulsion with crystal violet for one minute. The stain was then rinsed with distilled water. The stain was then pat dry with bibulous paper then observed under oil immersion to determine morphology. Upon completion

broth tubes A and B did not have any microbes inoculated into the tubes so it should not have been cloudy and that was what was seen. Tube C should have been cloudy because it had E. coli inoculated into the nutrient broth and that was also seen. A simple streak was also performed and it looks has if the loop went over previous streaks which should not have been done. A complex streak was also done. No colonies grew towards the end of the streak‚ this could be due to the inoculation loop being to hot

belts‚ caps‚ etc‚ are the most preferred clothing for today’s youth. This study discusses compositions and methods of reducing or preventing back staining of indigo dyes on the weft yarn and pocket of denim garments. The dye‚ as it is removed from the denim material‚ post treatment with cellulase or by a conventional washing process may cause ‘back staining’ or ‘redeposition’ on the denim material; e.g : re-coloration of blue threads and blue coloration of white threads‚ resulting in less contrast between

The plate count agar‚ CFC agar and cetrimide agar are used and provided different evidences on the isolation of Pseudomonas from the soil experiment. Firstly‚ the plate count agar is a medium for the enumeration of viable organisms in food‚ water‚ waste water and also from clinical samples‚ and thus it is non-selective to any species. Whereas the CFC agar is a selective agar which contains reduced amounts of cetrimide but also cephaloridine and fucidin are added to allow the isolation of most Pseudomonas

Discussion After doing a series of different biochemical tests for the isolated organisim from the sputum sample‚ it was concluded that the unknown Gram positive organism was Streptococcus pyogenes. The sputum sample was first inoculated in the agar plates MAC‚ SBAP‚ CHOC and also a direct gram stain of the sample was performed. After a day of incubation‚ the MAC agar gave a negative result‚ therefore it is not a Gram-negative bacteria and non-lactose fermenting. The SBAP and CHOC showed growth
