STUDIES ON THE BIOSYNTHESIS OF DIPICOLINIC ACID IN SPORES OF BACILLUS CEREUS VAR. MYCOIDES

Calcium dipicolinic acid-induced germination of Bacillus cereus spores.

Keynan, A. (University of Wisconsin, Madison) and H. O. Halvorson. Calcium dipicolinic acid-induced germination of Bacillus cereus spores. J. Bacteriol. 83:100-105. 1962.-The germination of spores of Bacillus cereus strain T can be initiated by calcium dipicolinic acid. The kinetics of germination are characterized by a long lag period followed by a rapid loss of refractility. The lag period di...

Dipicolinic acid-less mutants of Bacillus cereus.

When J. Powell (Biochem. J. 54:210, 1953) established dipicolinic acid (DPA) as an important constituent of bacterial spores, microbiologists became concerned about the function this compound serves and about its biosynthetic pathway. It is now generally considered that DPA is involved in the heat resistance of spores, but the mechanism is unknown. A number of schemes have been proposed for its...

Biosynthesis of dipicolinic acid in Bacillus megaterium.

Very little is known of the precursors of the dipicolinic acid (pyridine-2,6-dicarboxylic acid) in bacterial spores. C'4-2,6-diaminopimelic acid was shown to contribute to the formation of dipicolinic acid in Bacillus cereus var. mycoides (Perry and Foster, 1955; Foster, 1956) but the efficiency of the conversion was low, possibly because of a slow penetration of the cells by the exogenously su...

Methyl dipicolinate monoester from spores of Bacillus cereus var. globigii.

Dipicolinic acid location in intact spores of Bacillus megaterium.

Beta-attenuation analysis of intact spores of Bacillus megaterium containing tritium-labeled dipicolinic acid has shown that dipicolinic acid is located in the spore protoplast and not in the cortex.
