Isolation and characterization of a new plasmid from a Flavobacterium sp. which carries the genes for degradation of 2,4-dichlorophenoxyacetate.

abstract：:Some Escherichia coli strains with impaired cell division form branched cells at high frequencies during certain growth conditions. Here, we show that neither FtsI nor FtsZ activity is required for the development of branches. Buds did not form at specific positions along the cell surface during high-branching conditi...
