The Journal of Bacteriology is a monthly peer-reviewed scientific journal established in 1916. It is published by the American Society for Microbiology and the editor in chief is George A. O'Toole Jr. ( Dartmouth College ).
The complex and unique cell wall that makes members of the genus Mycobacterium difficult to destroy is also the reason for its extremely slow replication rate. Mycobacterium leprae prefers cool temperatures, slightly acidic microaerophilic conditions, and prefers the use of lipids as an energy source over sugars.
Unsolved problems relating to the structure and function of non-human organs, processes and biomolecules include: Korarchaeota (archaea). The metabolic processes of this phylum of archaea are so far unclear. Glycogen body. The function of this structure in the spinal cord of birds is not known. Arthropod head problem. A long-standing zoological ...
The culturing of prokaryotes typically involves bacteria, since archaea are difficult to culture in a laboratory setting. [4] To obtain a pure prokaryotic culture, one must start the culture from a single cell or a single colony of the organism. [5]
Capsules are more organized and difficult to remove compared to their slime layer counterparts. [5] Another highly organized, but separate structure is an S-layer . S-layers are structures that integrate themselves into the cell wall and are composed of glycoproteins, these layers can offer the cell rigidity and protection. [ 6 ]
For example, one study [12] used serial passage in baboons to create a strain of HIV-2 that is particularly virulent to baboons. Typical strains of HIV-2 only infect baboons slowly. [12] This specificity makes it challenging for scientists to use HIV-2 in animal models of HIV-1, because the animals in the model will only show symptoms slowly.

Obtaining a culture with a unified cell-cycle stage is useful for biological research where a particular stage in the cell cycle is desired (such as the culturing of parasitized cells [3]). Since cells are too small for certain research techniques, a synchronous culture can be treated as a single cell; the number of cells in the culture can be ...
