Purification and characterisation of endo-beta-1,4-glucanase and laminarinase enzymes from the gecarcinid land crab Gecarcoidea natalis and the aquatic crayfish Cherax destructor.
Laminarinase and endo-beta-1,4-glucanase were purified and characterised from the midgut gland of the herbivorous land crab Gecarcoidea natalis and the crayfish Cherax destructor. The laminarinase isolated from G. natalis was estimated to have a molecular mass of 41 kDa by SDS-PAGE and 71 kDa by gel filtration chromatography. A similar discrepancy was noted for C. destructor. Possible reasons f...

متن کاملFermentation of mucin and plant polysaccharides by strains of Bacteroides from the human colon.
Ten Bacteroides species found in the human colon were surveyed for their ability to ferment mucins and plant polysaccharides ("dietary fiber"). A number of strains fermented mucopolysaccharides (heparin, hyaluronate, and chondroitin sulfate) and ovomucoid. Only 3 of the 188 strains tested fermented beef submaxillary mucin, and none fermented porcine gastric mucin. Many of the Bacteroides strain...
متن کاملEvidence for extensive resistance gene transfer among Bacteroides spp. and among Bacteroides and other genera in the human colon.
Transfer of antibiotic resistance genes by conjugation is thought to play an important role in the spread of resistance. Yet virtually no information is available about the extent to which such horizontal transfers occur in natural settings. In this paper, we show that conjugal gene transfer has made a major contribution to increased antibiotic resistance in Bacteroides species, a numerically p...
متن کاملbeta glucanase (bgn13.1) expressed in transgenic brassica napus confers antifungal activity against sclerotinia sclerotiorum
brassica napus is an important oilseed crop and the yield loss due to fungal disease stem rot caused by sclerotinia sclerotiorum is a serious problem in cultivation of this crop. the pathogenesis-related (pr) protein, glucanase, hydrolyzes a major cell wall component, glucan, of the pathogenic fungi and acts as a plant defense barrier. in this study, a β-1,3-glucanase (bgn13.1) gene was isolate...
