american foulbrood (afb) is the most serious brood disease of the honey bee. traditional methods are reliable but rather slow simply because they are based on biochemical, morphological and physiological identification of cultivated isolates. the aim of this study is the detection of paenibacillus larvae larvae spores in honey and diseased larvae samples by culture and pcr. therefore 54 samp...

American foulbrood is the most destructive honeybee bacterial disease. The etiological agent, Paenibacillus larvae, has been classified into four genotypes by a repetitive-element PCR (ERIC I-IV) and 21 sequence types by multilocus sequence typing (ST1-21). In this study, we genotyped Japanese P. larvae isolates for the first time and revealed the presence of three genotypes (ERIC I-ST2, ERIC I...

A new xylanolytic strain, Paenibacillus favisporus CC02-N2, was isolated from sugarcane plantation fields in Brazil. The strain had a xylan-degrading system with multiple enzymes, one of which, xylanase Xyn30A, was identified and characterized. The enzyme is a single-domain xylanase belonging to family 30 of the glycosyl hydrolases (GH30). Xyn30A shows high activity on glucuronoxylans, with a V...

Genome sequences offer a broad view of host-pathogen interactions at the systems biology level. With the completion of the sequence of the honey bee, interest in the relevant pathogens is heightened. Here we report the genome sequences of two of the major pathogens of honey bees, the bacterium Paenibacillus larvae (causative agent for American foulbrood disease) and the fungus Ascosphaera apis....

Wastewater from the sweet potato starch industry is a large source of nutrient-rich substrates. We assessed whether this wastewater could be used to produce Paenibacillus polymyxa biofertilizer for foliar application to tea trees. Using the central composite design methods we experientially determined that the optimal culture conditions for P. polymyxa were pH, 6.5; temperature, 29.0 °C; and in...

Paenibacillus dauci sp. nov., a new kind of endophytic actinobacteria, is separated from the inner tissues of carrot sample, which forms intimated associations with carrot acting as biological control agents. Here we report a 5.37-Mb assembly of its genome sequence and other useful information, including the coding sequences (CDSs) responsible for biological processes such as antibiotic metabol...

Paenibacillus sp. XY044 is an endophytic bacterium isolated from the stem of a tea plant (Camellia sinensis cv. Maoxie). Here, we present the draft genome sequence of XY044, which includes genes encoding features related to plant growth promotion and biocontrol.
