taxonomic investigations on expressed and cryptic phospho-beta-glucosidases in enterobacteriaceae.in the enterobacteriaceae, beta-glucosides are catabolized by a complex system formed of three permeases, with partly overlapping substrate specificities, and two hydrolytic enzymes, phospho-beta-glucosidase a and b, which hydrolyze only phosphorylated beta-glucosides. some enterobacteriaceae such as klebsiella-aerobacter (enterobacter) possess the complete system; others possess only parts of it or may have a cryptic phospho-beta-glucosidase activity without permease activity. a screening test ...19694897109
deoxyribonucleic acid characterization of bdellovibrios.the guanine plus cytosine (gc) content of the deoxyribonucleic acid (dna) of 11 isolates of host-dependent (h-d) bdellovibrios and 18 host-independent (h-i) derivatives was determined from thermal denaturation curves and buoyant densities in cscl. the h-d and respective h-i cultures have gc contents which are identical within the limits of experimental error. most cultures of bdellovibrio bacteriovorus, including the holotype culture, have 50.4 +/- 0.9 moles% gc in their dna; two bdellovibrio is ...19694901360

(university of california, davis), and nancy l. baigent. parasitic interaction of bdellovibrio bacteriovorus with other bacteria. j. bacteriol. 91:2006-2017. 1966.-the interactions of the predatory parasite, bdellovibrio bacteriovorus, with erwinia amylovora, pseudomonas tabaci, and p. phaseolicola were examined by means of phase-contrast and electron microscopy. attachment of the bdellovibrio to the host cell is apparently initially reversible; detachment occurs infrequently ...19665327913
the ginkgo, the most ancient living tree. the resistance of ginkgo biloba l. to pests accounts in part for the longevity of this species.fossil records clearly demonstrate that the group of trees known as ginkgoales, of which today ginkgo biloba is the sole living member, date back over 200 million years. ginkgo bilboa itself is one of the oldest of living plants (4). it appears that the longevity of this tree and its long reproductive period are at least partially responsible for the persistence of the species. the resistance of these trees to pests such as insects, bacteria, viruses, and fungi has been studied. it is believed t ...19675341600

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 ...19705473883
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 ...19705488914
