| description of acetobacter oboediens sp. nov. and acetobacter pomorum sp. nov., two new species isolated from industrial vinegar fermentations. | two strains of acetobacter sp., lth 2460t and lth 2458t, have been isolated from running red wine and cider vinegar fermentations, respectively. taxonomic characteristics of the isolates were investigated. comparative analysis of the 165 rrna sequences revealed > 99% similarity between strain lth 2460t and the type strains of the related species acetobacter europaeus and acetobacter xylinus and between strain lth 2458t and acetobacter pasteurianus. on the other hand, low levels of dna relatednes ... | 1998 | 9734049 |
| application of molecular methods for routine identification of acetic acid bacteria. | recently many new species of acetic acid bacteria have been described. the description and identification as new species was based on molecular techniques (sequencing of the 16s rrna gene, dna base ratio (% gc) determinations and dna-dna hybridisation) and phenotypic characterization. in the present paper, we propose a fast and reliable method for the identification most of the species currently described based on the rflp-pcr of the 16s rrna. according to the proposed protocol, 1 species can be ... | 2006 | 16386324 |
| is the regulation of insulin signaling multi-organismal? | the sustained health of an individual animal depends on the composition and activities of its resident microbiota. a major challenge is to identify the processes by which the microbiota and animal interact, recognizing that this research should lead ultimately to novel strategies to promote human health. drosophila is emerging as a tractable model system to investigate these interactions. new evidence reveals that the gut microbiota promotes insulin signaling in drosophila, leading to increased ... | 2011 | 22169475 |
| microbiota-dependent priming of antiviral intestinal immunity in drosophila. | enteric pathogens must overcome intestinal defenses to establish infection. in drosophila, the erk signaling pathway inhibits enteric virus infection. the intestinal microflora also impacts immunity but its role in enteric viral infection is unknown. here we show that two signals are required to activate antiviral erk signaling in the intestinal epithelium. one signal depends on recognition of peptidoglycan from the microbiota, particularly from the commensal acetobacter pomorum, which primes th ... | 0 | 26567510 |
| the presence of acetobacter sp. in ensiled forage crops and ensiled industrial byproducts. | the presence of acetic acid bacteria (aab) in whole crop maize silage, whole crop wheat silage, pressed sugar beet pulp silage, grass silage and brewer's grains silage was investigated. aab could be isolated from whole crop maize silage, whole crop wheat silage and pressed sugar beet pulp silage, but could not be detected in grass silage (> 100 silo's tested) or brewer's grains silage (5 silo's tested). thirty aab isolates were characterized to genus level. all isolates, i.e. 20 from whole crop ... | 2001 | 15954628 |
| re-examination of the genus acetobacter, with descriptions of acetobacter cerevisiae sp. nov. and acetobacter malorum sp. nov. | thirty-four acetobacter strains, representing acetobacter aceti, acetobacter pasteurianus, acetobacter pomorum, acetobacter peroxydans, acetobacter lovaniensis, acetobacter estunensis, acetobacter orleanensis, acetobacter indonesiensis and acetobacter tropicalis, were subjected to a polyphasic study that included dna-dna hybridizations, dna base ratio determinations, 16s rdna sequence analysis and phenotypic characterization. two novel species are proposed, acetobacter cerevisiae sp. nov. and ac ... | 2002 | 12361257 |
| low-diversity bacterial community in the gut of the fruitfly drosophila melanogaster. | the bacteria in the fruitfly drosophila melanogaster of different life stages was quantified by 454 pyrosequencing of 16s rrna gene amplicons. the sequence reads were dominated by 5 operational taxonomic units (otus) at ≤ 97% sequence identity that could be assigned to acetobacter pomorum, a. tropicalis, lactobacillus brevis, l. fructivorans and l. plantarum. the saturated rarefaction curves and species richness indices indicated that the sampling (85 000-159 000 reads per sample) was comprehens ... | 2011 | 21631690 |
| characterization of acetobacter pomorum kjy8 isolated from korean traditional vinegar. | acetobacter sp. strains were isolated from traditional vinegar collected in daegu city and gyeongbuk province. the strain kjy8 showing a high acetic acid productivity was isolated and characterized by phenotypic, chemotaxonomic, and phylogenetic inference based on 16s rrna sequence analysis. the chemotaxonomic and phylogenetic analyses revealed the isolate to be a strain of acetobacter pomorum. the isolate showed a g+c content of 60.8 mol%. it contained ll-diaminopimelic acid (ll-a2pm) as the ce ... | 2014 | 25179899 |
| assessment of bacterial diversity in selected philippine fermented food products through pcr-dgge. | the bacterial population in several philippine fermented food preparations was assessed by pcr-denaturing gradient gel electrophoresis (pcr-dgge) of the 16s rrna gene (16s rdna). genomic dna was isolated directly from alamang (fermented shrimp paste), burong isda (fermented fish and rice), burong hipon (fermented shrimp and rice), burong mustasa (fermented mustard leaves), tuba (sugar cane wine), suka (vinegar) and sinamak (spiced vinegar) using one of two protocols, namely - mobio dna extractio ... | 2011 | 22146687 |
| Drosophila microbiome modulates host developmental and metabolic homeostasis via insulin signaling. | The symbiotic microbiota profoundly affect many aspects of host physiology; however, the molecular mechanisms underlying host-microbe cross-talk are largely unknown. Here, we show that the pyrroloquinoline quinone-dependent alcohol dehydrogenase (PQQ-ADH) activity of a commensal bacterium, Acetobacter pomorum, modulates insulin/insulin-like growth factor signaling (IIS) in Drosophila to regulate host homeostatic programs controlling developmental rate, body size, energy metabolism, and intestina ... | 2011 | 22053049 |
