Polygalacturonase of Erwinia carotovora.
The polygalacturonase, clearly differentiated from polygalacturonic acid trans-eliminase, produced in the culture fluid of Erwinia carotovora was purified 56-fold by means of acetone precipitation, acetate butfer extraction, and two successive treatments by chromatography on carboxymethyl cellulose. The purified enzyme is specific for nonmethoxylated polygalacturonic acid. It shows an optimum p...
متن کاملL-Asparaginase from Erwinia carotovora
The physicochemical properties of the antileukemic Lasparaginase from Erwinia carotovora have been studied and compared with those of the corresponding clinically effective enzyme from Escherichia coli B. Although both enzymes are tetramers with similar molecular weight, the amino acid compositions are distinctly different and the Erwinia enzyme is more basic as judged by polyacrylamide electro...
متن کاملBiological Control of Erwinia carotovora ssp. carotovora by Streptomyces Species
Ten isolates of Erwinia carotovora ssp. carotovora (Ecc) were isolated from infected potato tubers of Picasso, Sante, and Nevskiy varieties collected from different regions in Kyrgyzstan. Isolates were identified as Erwinia carotovora ssp. carotovora (Ecc) by standard bacteriological techniques and pathogenicity tests on tubers and also by PCR analyses. Tests on the pathogenicity of E. carotovo...
متن کاملPlasmid ColVBtrp maintenance in Erwinia carotovora.
Plasmid ColVBtrp maintenance in Erwinia carotovora cells was followed by measuring kinetics of elimination of plasmid genetic markers and loss of plasmid deoxyribonucleic acid. An E. carotovora mutant stably carrying plasmid ColVBtrp was isolated. Besides stable plasmid maintenance, the mutant showed altered sensitivity to male-specific phage MS2, sensitivity to drugs, and colony morphology.
متن کاملObservations on the bacteriophagy of Erwinia carotovora.
The lysis of Erwinia carotovora by bacteriophage has been reported by Coons and Kotila (1925), but the morphological characteristics of the virus could not be studied at that time, prior to the methods of electron microscopy, and some of the important physiological characteristics have not been investigated. In undertaking to obtain further data on these aspects of the problem, we have obtained...
