Abstract

The market growth of household cleaners can be associated with the recent switch to more natural products, products without chemicals that are harsh and harmful to the environment. This research study is aimed to determine which type of cleaner, natural or chemically condensed, is more effective against common bacteria and fungi. To test the cleaners efficiency, Escherichia Coli (aka E. Coli) and saccharomyces cerevisiae were cultured and selected cleaners were then applied. The selected cleaners were 409, Windex multi-surface, Seventh Generation, and a homemade lemon oil cleaner. The colonies were counted manually before application of cleaner and up to three days after. However a two-way ANOVA test showed that the time was insignificant and the interaction between time and the cleaners was insignificant. The results of the two way ANOVA test also showed that the p-values for the cleaners in both groups were less than 0.001 which is less than the critical value of alpha at 0.05, showing that the null hypothesis was rejected. The null hypothesis states that if different types of cleaners are applied to the microorganisms than the number of colonies for all the groups would stay the same.

The market growth of household cleaners can be associated with the recent switch to more natural products, products without chemicals that are harsh and harmful to the environment. This research study is aimed to determine which type of cleaner, natural or chemically condensed, is more effective against common bacteria and fungi. To test the cleaners efficiency, Escherichia Coli (aka E. Coli) and saccharomyces cerevisiae were cultured and selected cleaners were then applied. The selected cleaners were 409, Windex multi-surface, Seventh Generation, and a homemade lemon oil cleaner. The colonies were counted manually before application of cleaner and up to three days after. However a two-way ANOVA test showed that the time was insignificant and the interaction between time and the cleaners was insignificant. The results of the two way ANOVA test also showed that the p-values for the cleaners in both groups were less than 0.001 which is less than the critical value of alpha at 0.05, showing that the null hypothesis was rejected. The null hypothesis states that if different types of cleaners are applied to the microorganisms than the number of colonies for all the groups would stay the same.
