Antiseptics ( 70%, 91% Isopropyl and Iodine) on Ecoli growth Lab Report

Antiseptics ( 70%, 91% Isopropyl and Iodine) on Ecoli growth - Lab Report Example The E coli bacteria are among the most significant bacteria in the human digestive system. However, E coli bacteria have a number of genera that cause human diseases such as Shigella, Salmonella, and Yersinia (Todar 1). Physiological research has indicated that e coli bacterium is versatile and its habitat characteristics enable a perfect adaptation of the bacteria. E coli grow despite the presence or absence of oxygen and the wild type has no growth factor necessities. E coli respond to various environmental signals such as surrounding temperature, pH of the medium, chemicals, and other environmental factors because of the characteristics that make it a unicellular organism. E coli bacteria have multifaceted mechanisms, which they use to detect the presence of chemical in their environment such as antibiotics and antiseptics making it possible to synthesize enzymes to metabolize the chemical compounds leading to increased resistance of the bacteria to antiseptics. What is the effect of 70% concentration of isopropyl rubbing alcohol and 90 % concentration of iodine on Escherichia coli (E coli) growth? The experiment seeks to find the environment that best suits the growth of E coli bacteria and the reaction of the bacteria towards different concentrations of disinfectants. In addition, there are hypothesis that the experiment to test, which include the null and alternative hypothesis. In the quest to investigate the effect of concentration on the growth of E coli, if the percentage of the chemicals is increased, that is, the percentage of isopropyl alcohol and iodine is increased from 70% to 90% leads to a slight decrease in the growth rate of the E coli bacteria Medics have applied a wide range of products and methods used to treat, avoid, and control E coli bacteria. The use of chemicals such as antiseptics (isopropyl rubbing alcohol and iodine) has

Financial and Strategic Planning1 - Coursework Example The current liabilities in 2011 decreased significantly by 0.54. This means that the institution’s ability to convert its services into cash has reduced in 2011. The working capital is a ratio that indicates whether a given company is in a position to cover its short term debt by purely using its short term assets. This is obtained by obtaining the difference between the Current Assets and Current Liabilities. The institution’s working capital is significantly positive. However, the working capital reduced from 2010 to 2011. This means that even though the company is able to pay off its debtors in the short-term, they are more prone to bankruptcy in 2011 than in 2010. The debt/equity ratio is a measure of a given firm’s leverage. It essentially gives the amount of the processes and procedures that are financed by liability and that financed by the shareholder’s equity. It shows a company’s financial position relative to debtors and shareholders. The institution’s leverage indicates that in 2011 the institution adopted a more aggressive debt financing technique for its growth. This may potentially lead to the institution realizing volatile earnings owing to the increase in interest as a result of an increase in debt. This is evident in the fact that even though the institution has adopted a more aggressive debt financing approach, revenue reduced from $1,500,000 in 2010 to $1,300,000 in 2011. This raises concern as debt is increasing while revenue is reducing, bringing down the financial position of the institution relative to its debt. This also considerably reduces the institution’s credit rating, lowering the institution’s ability to seek debt financing in the
