| multiplex pcr for detection of botulinum neurotoxin-producing clostridia in clinical, food, and environmental samples. | botulinum neurotoxin (bont), the most toxic substance known, is produced by the spore-forming bacterium clostridium botulinum and, in rare cases, also by some strains of clostridium butyricum and clostridium baratii. the standard procedure for definitive detection of bont-producing clostridia is a culture method combined with neurotoxin detection using a standard mouse bioassay (smb). the smb is highly sensitive and specific, but it is expensive and time-consuming and there are ethical concerns ... | 2009 | 19684163 |
| metabolic modelling of syntrophic-like growth of a 1,3-propanediol producer, clostridium butyricum, and a methanogenic archeon, methanosarcina mazei, under anaerobic conditions. | clostridium butyricum can convert glycerol into 1,3-propanediol, thereby generating unfortunately a high amount of acetate, formate and butyrate as inhibiting by-products. we have proposed a novel mixed culture comprising c. butyricum and a methane bacterium, methanosarcina mazei, to relieve the inhibition and to utilise the by-products for energy production. in order to examine the efficiency of such a mixed culture, metabolic modelling of the culture system was performed in this work. the meta ... | 2010 | 19680695 |
| biohydrogen production from cellulosic hydrolysate produced via temperature-shift-enhanced bacterial cellulose hydrolysis. | a "temperature-shift" strategy was developed to improve reducing sugar production from bacterial hydrolysis of cellulosic materials. in this strategy, production of cellulolytic enzymes with cellulomonas uda e3-01 was promoted at a preferable temperature (35 degrees c), while more efficient enzymatic cellulose hydrolysis was achieved under an elevated culture temperature (45 degrees c), at which cell growth was inhibited to avoid consumption of reducing sugar. this temperature-shift strategy was ... | 2009 | 19604692 |
| effect of cod/so(4)2- ratio and fe(ii) under the variable hydraulic retention time (hrt) on fermentative hydrogen production. | the effect of chemical oxygen demand/sulfate (cod/so(4)(2-)) ratio on fermentative hydrogen production using enriched mixed microflora has been studied. the chemostat system maintained with a substrate (glucose) concentration of 15 g cod l(-1) exhibited stable h(2) production at inlet sulfate concentrations of 0-20 g l(-1) during 282 days. the tested cod/so(4)(2-) ratios ranged from 150 to 0.75 (with control) at ph 5.5 with hydraulic retention time (hrt) of 24, 12 and 6h. the hydrogen production ... | 2009 | 19555990 |
| functions of the clostridium acetobutylicium fabf and fabz proteins in unsaturated fatty acid biosynthesis. | the original anaerobic unsaturated fatty acid biosynthesis pathway proposed by goldfine and bloch was based on in vivo labeling studies in clostridium butyricum atcc 6015 (now c. beijerinckii) but to date no dedicated unsaturated fatty acid biosynthetic enzyme has been identified in clostridia. c. acetobutylicium synthesizes the same species of unsaturated fatty acids as e. coli, but lacks all of the known unsaturated fatty acid synthetic genes identified in e. coli and other bacteria. a possibl ... | 2009 | 19493359 |
| adding value to renewables: a one pot process combining microbial cells and hydrogen transfer catalysis to utilise waste glycerol from biodiesel production. | waste glycerol was converted to secondary amines in a one pot reaction, using clostridium butyricum and catalytic hydrogen transfer-mediated amination. | 2009 | 19377668 |
