cells of Clostridium acetobutylicum YM1 eliminated the lag phase and then improved the productivity of butanol and total ABE. Clostridium acetobutylicum belongs to the group, demonstrating peritrichous flagella and amylolytic activity. Nevertheless, by reacting epichlorohydrin with sorbitol (commercial products from Nagase ChemteX or JSI Co), isosorbide, phenols extracted from lignin, or by one pot reaction of furfural with trimethylsulfonium iodide in a basic aqueous medium leading to 2-furyloxirane, new 100% biobased epoxy prepolymers have been prepared and tested.102,103,104 Another route is the enzymatic epoxidation of cardanol.105, However, “bio-phenol” is a still missing building block and more generally, modified aromatic-based epoxy prepolymers would be desirable because of the classification of BPA as CMR R3 substance, even more so, as the discussion around the endocrine potential of BPA has entered the greater public. Requires numerous vitamins in addition to amino acids. This is mainly because solvents and organic acids could be used for production of fine chemicals such as butyl butyrate, butyl oleate, etc. They show that artificially engineered ATP consumption through a pathway modification can drive this reaction forward and enables the direct photosynthetic production of 1-butanol from cyanobacterial S. elongatus PCC 7942. Light-microscopy picture of forespores of Clostridium acetobutylicum ATCC 824. Their secretion yields range from 0.3 to 15 mg/L. C. acetobutylicum was the most reported in acetone-butanol-ethanol (ABE) fermentation for synthesis of biobutanol with higher yields [5, 6]. Initially, acetone was needed in the production of synthetic rubber. The presence of gene cassette of agrB and agrD homologues suggests the potential to produce cyclic peptide, and the presence of two-component regulatory gene orthologue suggests the potential to sense the produced cyclic peptide autoinducer. Recent studies have shown that this solventogenic bacterium can be used as a host for heterologous production and secretion of individual cellulosomal components, termed the minicellulosome. Among the clostridia, Clostridium acetobutylicum is a microorganism of choice as (i) it has already been used for the industrial production of solvent (Cornillot and Soucaille, 1996) and (ii) the genetic tools for gene knockout or gene over-expression are currently available (Mermelstein and Papoutsakis, 1993; Green et al., 1996). The inactivation of agrA did not affect the ability of the pathogen to invade and multiply in mammalian cells in vitro. Lan and Liao (2011) discuss cyanobacterial biobutanol production from Synechococcus in a paper originating from the lead laboratory of Liao in the United States with 172 citations. Clostridium acetobutylicum cells cannot be identified by their metabolic products alone, as solvent may be absent and several related species are also able to form butanol – for example, Clostridium beijerinckii (formerly Clostridium butylicum), Clostridium saccharoperbutylacetonicum, or Clostridium saccharobutylicum. J.-P. Pascault, ... P. Fuertes, in Polymer Science: A Comprehensive Reference, 2012, There is not yet an easy access at the horizon to the production of epoxy monomers from renewable resources. They observe that substitution of bifunctional aldehyde/alcohol dehydrogenase (AdhE2) with separate butyraldehyde dehydrogenase (Bldh) and NADPH-dependent alcohol dehydrogenase (YqhD) increased 1-butanol production by fourfold. Also, a recent paper reported that in-frame deletion of agrA and agrD resulted in an altered adherence and biofilm formation on abiotic surfaces, suggesting the involvement of the agr system of L. monocytogenes during the early stages of biofilm formation.209 The production of thiolactone peptide was also confirmed in the culture supernatant of L. innocua and L. monocytogenes (N.
