What is a bacterial colony? A bacterial colony is a mass of bacterial cells that have arisen from a single mother cell. A single mother cell reproduces to create a group of genetically identical cells to form a colony with different morphology depending on the type of bacteria. ...
The first step in isolating the bacteria is to streak for individual colonies. Next, a microbiologist will examine the visible appearance, or , of the isolated colonies in order to try and recognize different species. Some bacterial colonies are visually very different. Microbiologists use a ...
and allow transfer of a single colony to a sterile medium for cultivation of a pure culture. This exercise also shows how many diverse bacteria and fungi are present
isolated bacteria, for which transformation methods are difficult to establish. Results Fabrication of IMM layers Full size image IMMs cancel background reflection Full size image Cell imaging at the interface between liquid and IMM Full size image...

Indeed one of the fundamental distinctions between different types of bacteria is made on the basis of the wall structure. The Gram stain functions to distinguish between these marked differences in structure. Figure 3 shows a comparison of the cell structures of Gram-positive and Gram-negative ...
Mycobacteroides abscessus is one of the most resistant bacteria so far known and causes severe and hard to treat lung infections in predisposed patients such as those with Cystic Fibrosis (CF). Further, it causes nosocomial infections by forming biofilms on medical devices or water reservoirs. An...
Three Vibro alginolyticus strains( ZJ-51,E324 and E381) with phase variation were selected to conduct seawater long-term starvation experiments to study viable bacteria density at different periods,colony morphology observation under optical microscope,cell morphology observation under scanning electron micro...
