Identification, characterization and regulation studies of the aconitase of Paracoccidioides brasiliensis.

A protein species preferentially expressed in yeast cells with a molecular mass of 80 kDa and isoeletric point (pI) of 7.79 was isolated from the proteome of Paracoccidioides brasiliensis and characterized as an aconitase (ACO) (E.C.

Construction of Bacillus thuringiensis wild-type S76 and Cry- derivatives expressing a green fluorescent protein: two potential marker organisms to study bacteria-plant interactions.

Collectively, the species Bacillus thuringiensis, Bacillus cereus, and Bacillus anthracis represent microorganisms of high economic, medical, and biodefense importance. Although the genetic correlation and pathogenic characteristics have been extensively dissected, the ecological properties of these three species in their natural environments remain poorly understood. Thus, a tractable marker for detecting these bacteria under specific environmental and physiological conditions is a valuable tool.
