The first bacteria chosen was Escherichia coli (E-coli) from the genus enterobacteriaceae.
Its cells are found in pairs or singularly being typically motile and fimbriate. Their
optimum temperature for growth is 37C. This bacteria respires under aerobic conditions
and fermentation. E-coli is found in part of the microflora of the human intestine as well as
other animals. Some strains are pathogenic.
The second bacteria was Baccilus Megatherium belonging to the genus Baccilus.
Bacc-Meg is a gram positive bacteria and its cells are rod shaped often 0.5-1.5µm 2-6µm
and are typically motile. Bacc-Meg can be either aerobic or facultatively anaerobic as well
as being respiratory or facultatively fermentative. It can also grow in nutrient agar.
