| stability of microbial communities in goat milk during a lactation year: molecular approaches. | the microbial communities in milks from one herd were evaluated during 1-year of lactation, using molecular methods to evaluate their stability and the effect of breeding conditions on their composition. the diversity of microbial communities was measured using two approaches: molecular identification by 16s and 18s rdna sequencing of isolates from counting media (two milks), and direct identification using 16s rdna from clone libraries (six milks). the stability of these communities was evaluat ... | 2007 | 17604934 |

| terminal olefin (1-alkene) biosynthesis by a novel p450 fatty acid decarboxylase from jeotgalicoccus species. | terminal olefins (1-alkenes) are natural products that have important industrial applications as both fuels and chemicals. however, their biosynthesis has been largely unexplored. we describe a group of bacteria, jeotgalicoccus spp., which synthesize terminal olefins, in particular 18-methyl-1-nonadecene and 17-methyl-1-nonadecene. these olefins are derived from intermediates of fatty acid biosynthesis, and the key enzyme in jeotgalicoccus sp. atcc 8456 is a terminal olefin-forming fatty acid de ... | 2011 | 21216900 |

| changes in bacterial communities accompanied by aggregation in a fed-batch composting reactor. | the contents of fed-batch composting (fbc) reactors often aggregate after prolonged operation. this process leads to irreversible breakdown of the decomposition reaction and possible alteration of the bacterial communities. we compared the structures of bacterial communities in reactors under aggregate and optimal conditions. the results of 16s rrna gene clone analysis showed that populations of the family bacillaceae (such as bacillus spp., cerasibacillus spp., gracilibacillus spp.), which domi ... | 2008 | 18231830 |
| salinicoccus jeotgali sp. nov., isolated from jeotgal, a traditional korean fermented seafood. | a novel, moderately halophilic, gram-positive coccus, designated strain s2r53-5(t), was isolated from jeotgal, a traditional korean fermented seafood. the organism was strictly aerobic, non-motile, non-sporulating and catalase- and oxidase-positive. strain s2r53-5(t) grew in the presence of 0.5-15 % (w/v) nacl and at ph 6.5-11.0, with optimum growth at 5 % (w/v) nacl and ph 7.0. the temperature range for growth was 20.0-30.0 degrees c, with an optimum temperature of 30 degrees c. phylogenetic an ... | 2007 | 17329798 |
| microbial community structure and dynamics of dark fire-cured tobacco fermentation. | the italian toscano cigar production includes a fermentation step that starts when dark fire-cured tobacco leaves are moistened and mixed with ca. 20% prefermented tobacco to form a 500-kg bulk. the dynamics of the process, lasting ca. 18 days, has never been investigated in detail, and limited information is available on microbiota involved. here we show that toscano fermentation is invariably associated with the following: (i) an increase in temperature, ph, and total microbial population; (ii ... | 2007 | 17142368 |
