Growth of Bacteria in Solutions Essay Example | Topics and Well Written Essays - 500 words
Growth of Bacteria in Solutions - Essay Example According to Levinson (2015), the scientific findings imply that the growth of both Staphylococcus epidermises and Saccharomyces cerevisiae is favored by low concentrations of NaCl. At 1% NaCl, moderate and high growth rates were observed for Saccharomyces cerevisiae and Staphylococcus epidermises respectively. Therefore, it means that even at hypotonic solutions, the growth rate of Staphylococcus epidermises faster than that of Saccharomyces cerevisiae. A similarity in growth behavior of the two bacteria was noted in 1% NaCl whereby both solutions turned cloudy. As the concentration of NaCl continued to increase, the growth of both bacteria decreased. According to Queck and Otto (2014), the growth of Staphylococcus epidermis can be experienced in NaCl concentrations of up to 10% but no growth can be experienced in 15% NaCl. On the hand, Saccharomyces cerevisiae showed scant growth in 15% NaCl. Scientific findings on the ability of bacteria to grow in solutions of different concentrations provide facts about the growth of Staphylococcus epidermis and Saccharomyces cerevisiae in 1%, 7% and 15% NaCl.It was noted that growth of the two bacteria decreased as the NaCl concentration increased.These findings support the argument that both Staphylococcus epidermis and Saccharomyces cerevisiae thrive in low concentrations of NaCl. The study showed that it was only Saccharomyces cerevisiae able to survive in 15% NaCl while the growth of Staphylococcus epidermis was limited to 10% NaCl.
