Pseudomonas ovalis

Series reaetions also oeeur in oxidation proeesses where the required produet may oxidize further. An example is the produetion of maleie anhydride from the oxidation of benzene. In this ease, the maleie anhydride ean be oxidized further to earbon dioxide and water. Another example of a series reaetion oeeurs in the bioehemieal reaetion in whieh Pseudomonas ovalis is used to eonvert glueose to glueonie aeid via glueonolaetone in bateh eulture. This first order reaetion is represented by...

A mathematical model of the fermentation of the bacterium Pseudomonas ovalis, which produces gluconic acid, has been developed (Rai Constantinides, AIChE Symposium Series 69 No 132, 114, 1973). This model which describes the dynamics of the logarithmic growth phase is summarized as follows. 

Fig. 10.6 Amino acid sequences of Mn- and Fe-SODs. Yeast, Saccharomyces cerevisiae N. plumbagi., Nicotianaphimbaginifolia B. stearo., Bacillus stearothermophilus E. coli Escherichia coli A. thaliana, Arabiopsis thaliana-, P. ovalis, Pseudomonas ovalis. Residues conserved in Mn-SODsand/or Fe-SODs are boxed.

Figure 10.6 shows the alignment of amino acid sequences of Fe- and Mn-SODs so far determined. The amino acid sequences of Fe-SODs show a high degree of homology with those of Mn-SODs. His-26, His-73, Asp-156, and His-16049) in E. coli Fe-SOD serve as the metal ligands (Fig. 10.7) and are conserved in both Mn- and Fe-SODs from other organisms (Fig. 10.6). The three-dimensional structures have been determined for Mn-SODs from Thermus thermophilus HB8 (2.4 A)50) and Bacillus stearothermophilus (2.4 A)5I,52) and for Fe-SODs from E. coli (3.lA)53) and Pseudomonas ovalis (2.9 A).54) The polypeptide chain of the monomer of Mn-SOD is composed of two domains one has an all-a structure and the other an a) ft structure, with the Mn ion bound between them (Fig. 10.8).

A Pseudomonas strain hydroxylates p-menthane to cis-p-menthan-l-ol,84 and microbiological reduction of carvotanacetone with Pseudomonas ovalis gives similar results85 to those obtained with carvone (Vol. 5, p. 24, incorrectly reports inversion at C-4). (—)-Carvotanacetone (30) gives (+)-carvomenthone (31), (—)-... 

Fe4S42+ and [3Fe-xS] clusters have also been identified in Pseudomonas ovalis ferredoxin using the NMR spectral method (41). Again it is claimed that the [3Fe-4S] cluster is formed from [4Fe-4S] during the purification procedures. Such a process has also been observed in aconitase, which has only a simple Fe/S cluster (42).

Both naturally occurring enantiomers of carvone were selectively reduced by B. sulfurescens (Scheme 71). (-)-Carvone was reduced to (-h)-dihydrocarvone (trans) and further to (-H)-neodihydrocarveol, whereas (-i-)-carvone was reduced to (-)-isodihydrocarvone (cis), which was then converted to (-)-neo-isodihydrocarveol. Similar reductions with identical stereoselectivities were observed earlier with Pseudomonas ovalis (strain 6-1) and with a strain of Aspergillus niger. ... 

NFM and RSM are used in this case study to optimize the gluconic acid production. The primary objectives of this process are to maximize simultaneously the overall production rate and the final concentration of gluconic acid. The simulation of the fermentation of glucose to gluconic acid by the micro-organism Pseudomonas ovalis in a batch stirred tank reactor is performed. The overall biochemical reaction can be expressed as ...
