NATURAL 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 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 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 کاملBiosynthetic utilization of ethanolamine by Erwinia carotovora.
The purified obelin was electrophoresed on 7 % polyacrylamide gels in Tris-glycine buffer, pH 8.3, containing 0.1 mM-EDTA. Gels stained with Coomassie Brilliant Blue showed a single band at the buffer front, which correlated in position with luminescent activity. This activity could be eluted from unstained gel slices by soaking them overnight in 0.1 mM-EDTA-lOmM-Hepes, pH 7.0, at 4°C. Obelin i...
متن کاملEfficient transformation of Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica.
We used a modified version of the method of Hanahan (D. Hanahan, J. Mol. Biol. 166:557-580, 1983) to transform Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica with the plasmids pBR322, pBR325, and pAT153. The transformation frequency ranged from 1 X 10(2) to 4 X 10(4) colonies per micrograms of plasmid DNA. The nature of these transformants was confirmed by plasmid ana...
