Paenibacillus The taxonomic status of the type species of the genus Paenibacillus cannot be easily determined according to the rules of the Bacteriological Code (1990 Revision) since the rules may be interpreted in an ambiguous way. In 2002, the Judicial Commission decided that the type species of the genus Paenibacillus is ¤ Paenibacillus polymyxa. : XIE (C.H.) and YOKOTA (A.): Paenibacillus terrigena sp. www.bacterio.cict.fr /p/paenibacillus.html   (6093 words)

Genome Encyclopedia of Microbes A strain of Paenibacillus polymyxa capable of suppressing plant diseases and promoting plant growth was isolated from the rhizosphere of winter barley grown in Chonnam province, Korea and designated E681 (Ryu and Park, 1997). The genus Paenibacillus (Ash et al., 1993; previously Bacillus), comprised of more than thirty species, is facultatively anaerobic and belongs to endospore-forming low-G+C Gram-positive bacilli. Paenibacillus polymyxa produces fusaricidin-type antifungal antibiotics active against Leptosphaeria maculans, the causative agent of flleg disease of canola. www.gem.re.kr /htm/g_projects_02.htm   (493 words)

OhioLINK ETD: IYER, NEERAJA The results of the study confirm the hypothesis for completely stirred tank reactors, but suggest that selective pressure applied using a plug flow configuration is sufficient to eliminate the impact of bioaugmentation and control bulking. Second, a survey of fifteen dairy wastewater treatment plants was conducted to evaluate the extent of Paenibacillus related non-filamentous sludge bulking. Although an assortment of culture-based methods was unsuccessful for identifying a novel strain of Paenibacillus, future work should be performed to isolate a relevant strain of Paenibacillus to be used to determine the mechanism for non-filamentous sludge bulking due to this microorganism. rave.ohiolink.edu /etdc/view?acc_num=ucin1093025089   (340 words)

Bees for Development :: The spread and control of American foulbrood The disease is caused by the spore-forming bacterium Paenibacillus larvae larvae. Our field experiments with inoculation of Paenibacillus larvae larvae spores have also shown that infected colonies may eliminate the infections and that no simple correlation exists between the number of spores in the honey and the first visible signs of AFB in capped brood cells. Furthermore, strains of Paenibacillus larvae larvae may develop resistance to sulfathiazole and oxytetracycline after continuous use of the drugs (Morse and Shimanuki, 1990). www.beesfordevelopment.org /info/info/disease/the-spread-and-control-of.shtml   (1536 words)

CiteULike: Directed evolution of beta -glucosidase A from Paenibacillus polymyxa to thermal resistance.   (Site not responding. Last check: 2007-10-19) The beta-glucosidase encoded by the bglA gene from Paenibacillus polymyxa has a half-life time of 15 min at 35 degrees C and no detectable activity at 55 degrees C. We have isolated random mutations that enhance the thermoresistance of the enzyme. Following a directed evolution strategy, we have combined some of the isolated mutations to obtain a beta-glucosidase with a half-life of 12 min at 65 degrees C, in the range of resistance of thermophilic enzymes. The putative causes increasing thermoresistance are as follows: the formation of an extra salt bridge, the replacement of an Asn residue exposed to the solvent, stabilization of the hydrophobic core, and stabilization of the quaternary structure of the protein. www.citeulike.org /user/papatonyhill/article/907125   (399 words)

Manual of standards for diagnostic tests and vaccines, 4th edition, 2000 Paenibacillus larvae can be distinguished biochemically from other spore-forming bacilli because it reduces nitrate to nitrite and is negative for catalase production; these characteristics and the bacterium's growth requirements will give a positive identification. Paenibacillus larvae (White), the causative organism, is a bacterium that can produce over one billion spores in each infected larva. Paenibacillus larvae almost invariably reduces nitrate to nitrite (8). www.oie.int /eng/normes/mmanual/ancien_manuel/A_00105.htm   (2319 words)

New bacteria strains found in prostatitis patients - UrologyTimes The two strains, Proteobacterium species and Paenibacillus species, have never before been identified in patients with prostatitis. We also found it in one case in the literature, a case of osteomyelitis, but this is the first time it has been identified in the urinary tract in man," said Keith Jarvi, MD, associate professor of urology at the University of Toronto and Mount Sinai Hospital, Toronto. In addition to identifying the bacteria for the first time, the team also found that Paenibacillus was far more common in men with prostatitis than the controls. www.urologytimes.com /urologytimes/article/articleDetail.jsp?id=1938   (653 words)

Epsilon Dissertations and Graduate Theses Archive - Bacterial-fungal interactions highlighted using microbiomics: One of the actively growing bacteria, Bacillus cereus strain VA1, was isolated from the soil, tagged with green fluorescent protein (GFP) and shown to clearly attach to AM fungal hyphae. It was subsequently shown, however, that this bacterial strain had preferences for non-vital AM fungal hyphae, whereas one of the control strains, Paenibacillus brasilensis PB177, actually showed greater attachment to vital hyphae. Finally, Paenibacillus brasilensis PB177, previously shown to be associated with AM fungi, was shown to inhibit growth of several phytopathogenic fungi. In summary, the results of these studies provide novel valuable insights to consider when developing combined microbial inocula (e.g. diss-epsilon.slu.se /archive/00001009   (386 words)
