Factorial analysis on bacillus Sp. removal using garlic solution

Biofilm is a complex structure adhering to surfaces that are regularly in contact with water, consisting of colonies of bacteria and other microorganisms. Many different microbes can be found in biofilm such as Bacillus sp., Listeria monocytogenes, Staphylococcus sp., Escherichia coli and many more....

Garlic solution was used to remove Bacillus sp. In this study, garlic solution was prepared by crushing the garlic and mixed it with water. The selected factors were ratio of water to garlic (W/G) (1:1 and 1:5), ratio of garlic solution to Bacillus sp. (GS/B) (1:1 and 1:3), agitation speed (50-100 rpm) and reaction time between Bacillus sp. and garlic (12-24 hours).
