| eliminative split of pectic substances by phytopathogenic soft-rot bacteria. | culture filtrates of erwinia carotovora and bacillus polymyxa split pectic substances to yield a product that absorbs at 230 mmicro, and which reacts with thiobarbituric acid to form a substance that absorbs at 547 mmicro. this product is believed to be a c-4,5-unsaturated oli-gouronide. the preferred substrate is polygalacturonic acid rather than pectin; the enzyme, provisionally named polygalacturonic-trans-eliminase, is activated by calcium. | 1962 | 13916373 |

| regulation of pectate lyase synthesis in pseudomonas fluorescens and erwinia carotovora. | inducible synthesis of extracellular pectate lyase occurs in erwinia carotovora, a bacterial soft-rot pathogen of plants, and, to a lesser extent, in a nonpathogenic isolate of pseudomonas fluorescens. a combination of pectin and a heat-labile factor in fresh potato tissue or acetone powders of the tissue provided the best carbon source for induction. yields of inducible pectate lyase were much greater than those usually reported. the pathogen, but not the saprophyte, produced a small amount of ... | 1970 | 5473883 |
| stimulation by erwinia carotovora of the synthesis of ethylene in cauliflower tissue. | the synthesis of ethylene by cauliflower floret tissue was increased when the tissue was inoculated with the soft-rot bacterium erwinia carotovora. this effect was clearly associated with the production of pectic enzymes by the micro-organism. these enzymes, acting together with the plant enzymes, stimulated the production of ethylene from methionine. the increased synthetic activity was due to the release and increased activity of a glucose oxidase enzyme apparently attached to plant cell-wall ... | 1970 | 5488914 |

| decomposition of 2,4-dihydroxy-7-methoxy-2h-1,4-benzoxazin-3(4h)-one in aqueous solutions. | cyclic hydroxamic acids present in some species of gramineae have been reported to be important in resistance of these plants to fungi and insects. since the nonglucosylated forms of these acids are unstable in aqueous solution, in vitro methods for the measurement of their antibiotic properties have been difficult. kinetics of the decomposition of 2,4-dihydroxy-7-methoxy-2h-1,4-benzoxazin-3(4h)-one (dimboa), the major hydroxamate in corn (zea mays l.) extracts, were studied in buffered aqueous ... | 1978 | 16660388 |
| factors that influence the activity of 2,4-dihydroxy-7-methoxy-2h-1,4-benzoxazin-3(4h)-one on erwinia species in growth assays. | factors affecting the inhibitory activity of 2,4-dihydroxy-7-methoxy-2h-1,4-benzoxazin-3(4h)-one (dimboa) against erwinia carotovora, a nonpathogen of zea mays l., and against a maize pathovar of erwinia chrysanthemi (ecz) were examined. most experiments were performed with dimboa dissolved in a bacterial growth medium containing 10 g/liter of sucrose, inorganic salts, and 1 g/liter of casamino acids at ph 6.75. when temperature and ph were held constant, inhibition of e. carotovora varied linea ... | 1978 | 16660389 |
| improvement in the therapeutic, immunological, and clearance properties of escherichia coli and erwinia carotovora l-asparaginases by attachment of poly-dl-alanyl peptides. | the chemical modification of both escherichia coli and erwinia carotovora asparaginases by a dl-alanine-n-carboxyanhydride polymerization technique produced modified enzymes which had greater protease stability, retained most of their catalytic activity, and demonstrated a 7- to 10-fold prolongation in plasma clearance properties in normal mice and rats. concomitantly, plasma substrate depletion was also extended 5 to 13 days longer for the modified as compared with the native enzymes. for prepa ... | 1979 | 376113 |
| "self-catabolite repression" of pectate lyase in erwinia carotovora. | the induction of pectate lyase of erwinia carotovora was repressed by a high concentration of its inducer. the concomitant addition of cyclic adenosine 3',5'-monophosphate reversed this repression. | 1979 | 217862 |
| the post-harvest fruit rots of tomato (lycopersicum esculentum) in nigeria. | a survey of the post-harvest fruit rot diseases of tomato was conducted in five states of nigeria. during severe infections, the diseases could cause 25% loss at harvest and 34% loss of the remaining product in transit, storage and market stalls; thus giving an overall loss of about 50% of the product. two types of rots, soft and dry were recognised. the soft rot was found to account for about 85% and the dry rot about 15% of the overall loss. erwinia carotovora, rhizopus oryzae, r. stolonifer, ... | 1979 | 471028 |
| [interest of gamma-glutamyltransferase in "enterobacteriaceae" (author's transl)]. | gamma-glutamyltransferase (gammagt) could be detected in 86,6% of 3,027 strains of enterobacteriaceae, by the use of gamma-l-glutamin-p-nitranilide acid for substrate. the following species produced gamma gt: citrobacter freundii, levinea malonatica, l. amalonatica, klebsiella pneumoniae, k. oxytoca, k. ozaenae, enterobacter aerogenes, e. cloacae, e. agglomerans, e. gergoviae, k. ozaenae, enterobacter aerogenes, e. cloacae, e. agglomerans, e. gergoviae, hafnia alvei, erwinia carotovora, serratia ... | 1980 | 6104464 |

| serological relationships among flagella of erwinia carotovor var. atroseptica and some e. carotovora var. carotovora serogorups. | the 2 erwinia carotovora var. atroseptica serogroups and 2 out of 16 e. carotovora var. carotovora serogroups previously established on the basis of diffusible somatic antigens were shown to be serologically related by agglutination procedures using whole cells. the common agglutinating antigen in serogroups i, iii, v, and xviii was heat labile and identified as the bacterial flagella by the fluorescent antibody staining procedure. a few strains in serogorups i and iii apparently lacked flagella ... | 1980 | 6156748 |
| microbial metabolism of amino alcohols. biosynthetic utilization of ethanolamine for lipid synthesis by bacteria. | 1. ten bacteria utilizing [2-14c]ethanol-2-amine as the sole or major source of nitrogen for growth on glycerol + salts medium incorporated radioactivity into a variety of bacterial substances. a high proportion was commonly found in lipid fractions, particularly in the case of erwinia carotovora. 2. detailed studies of [14c]ethanolamine incorporation into lipids by five bacteria, including e. carotovora, showed that all detectable lipids were labelled. even where phosphatidylethanolamine was th ... | 1980 | 7370003 |
| interaction between age of maize plants, environmental factors, and inoculum strength of erwinia carotovora var. chrysanthemi on the extent of stalk rot incidence. | for optimum disease incidence and maximum mortality of maize plants, due to erwinia carotovora var. chrysanthemi (burkholder et al.) dye, a temperature of 35 degrees c accompanied with 70 per cent humidity and inoculum potency of 2 x 10(8) cells/ml were essential for younger plants of 15 and 30 days of age. on the other hand, 45- and 60-day-old plants, due to acquisition of a certain degree of maturity, although responding and showing maximum disease symptoms at the same temperature of 35 degree ... | 1980 | 7376756 |
