The Effects On Growth Lab

Introduction- There is many important factors that will affect the generate of microbes. These factors butt joint sometimes speed up or decompress down growth extremity, or even spot the process if the conditions are too extreme. These factors are temperature, pH, and osmotic pressure. I guess the temperature or the pH factor will piss the nigh effect on the microbes in the experiment. Materials: Nutrient finish fund of staphylococcusylococcus epidermidis, genus genus Serratia marcescen, and Bacillus megaterium. 2 Nutrient alimentary agar Slants 5 resistances of nutrient blood line An incubator at 25°C and 37°C and 55°C 5 petri plates 5 pipettes 1 tube of nutrient broth 1 bottle of nutrient agar pee baths at different temperatures Petri plates of agar 0.5% NaCl Petri plates of agar 5% NaCl Petri plates of agar 10% NaCl petri plates of milk salt agar 15% NaCl method acting The method can be located in the lab manual. We were to inf orm each one of our petri plates or our broth tubes or our tube slants with each one of the 3 cultures we were given. We then followed the directions in move the different specimen in either the torrid pissing baths, in the incubator or fridge banding at the specified temperatures to find the optimum growth of the cultures.
