Biological 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 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 کاملPolygalacturonase 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 کاملNATURAL EXTRACTS OF MUSHROOM AND GARLIC AS BACTERICIDE ALTERNATIVES AGAINST POTATO SOFT-ROT BACTERIA, Erwinia carotovora subsp. carotovora
Current study aimed to search for safe and effective natural products to control the potato soft-rot disease, Erwinia carotovora subsp. carotovora. Antibacterial efficiency of edible mushroom extracts (MEs) and garlic essential oil (EO) were compared with two bactericides; streptrol and oxolinic acid as well as two fungicides; mancopper and copper oxychloride. Bioassay experiments were conducte...
متن کاملStructure of the core oligosaccharide from lipopolysaccharide of Erwinia carotovora.
The lipopolysaccharide of Erwinia carotovora was analyzed by quantitative sugar analysis, methylation analysis, and chromic oxide oxidation. This led to the following structure of the core oligosaccharide: (Formula; see text).
