Summary Introduction
To determine:
The genus of bacteria that is gram negative, lactose-positive rod that produces indole but nor hydrogen sulfide gas.
Introduction:
Bacteria are biological cells that are prokaryotic in nature. They are the first living form to occur on the Earth and are found in most of the habitats. The length of bacteria varies a lot and they can be rod, spherical, or spiral in shape.
