Phthalate esters are widespread contaminants and the dialkyl phthalates are hydrolyzed before degradation of the resulting phthalate (Eaton and Ribbons 1982), which is discussed in Chapter 8, Part 3. For dimethyl phthalate, dimethyl terephthalate, and dimethyl isophthalate only partial hydrolysis may take place (Li et al. 2005). Cocaine is hydrolyzed to benzoate and ecgonine methyl ester by a strain of Pseudomonas maltophilia (Britt et al. 1992).

FIGURE 13.1 An EPR-monitored redox titration of two [2Fe-2S] clusters. A 2Fe cluster in a ferredoxin (E° = -170 mV) and one in an oxygenase enzyme (E° = -20 mV) from Pseudomonas maltophilia were each titrated with dithionite in the presence of a mediator mix. Each point is the EPR amplitude from an individual sample drawn at the indicated solution ii-value. The fit is based on Equation 13.12. (Data from Chakraborty et al. 2005.)...

The enzyme that catalyzes the stereospecific reduction of ketopantoic acid to D-pantoic acid was isolated in a crystalline form from Pseudomonas maltophilia [109] (see Tables 4 and 5). It is an NADPH-dependent enzyme and is strictly specific to ketopantoic acid. The observation that mutants lacking this enzyme require either D-pantoic acid or pantothenic acid for growth and that the revertants regain this activity indicates that the enzyme is ketopantoic acid reductase (EC 1.1.1.169) and is involved in the pantothenate biosynthesis. 

Recent publications 0,4) in regard to the latter two plants indicate that they were also toxic to two bacteria which occur in the gut of the tobacco budworm Heliothis virescens (Fab.) and the corn earworm Heliothis zea (Boddie). The compounds, rhamnetin 3-0-glucoside and isoquercitrin, were isolated (3) from H camporum based upon their activity against Pseudomonas maltophilia and Enterobacter cloacae Also, a procyanidin was isolated (4) from Mj floribundum on the basis of activity against P. maltophilia.

The use of proteases from bacterial isolates was reported by Shimahara and Takiguchi (1988) as well as Tsai et al. (2002) who used a bacterial protease from Pseudomonas maltophilia for DP without alkali. After 24 h, the remaining protein content of crustacean shell was about 1%. Similarly, a protease from Bacillus sp. TKU004 was employed at optimized conditions in a 2% slurry of squid pen powder (Wang et al. 2006). DP was 63% after the second day and peaked at 73% after the third day. 

In bacterial fermentation for chitin and chitosan production, the most often applied strains are Lactobacillus sp., Bacillus sp., Pseudomonas sp and S. marcescens. The microbial DP process is little efficient, ranging between 50% and 85% DP rate depending on materials, used microorganism, fermentation type, and time. Rao et al. (2000) cultured shrimp biowaste with L. plantarum and achieved 75% DP. Bautista et al. (2001) achieved 81.5% DP from crayfish using Lactobacillus pentosus 4023. Fermentation of crab shell wastes with 10% S. marcescens FS-3 inoculum resulted in DP of 84% and DM of 47% at 7 days culture (Jo et al. 2008). Squid pen for the preparation of P-chitin were deproteinized by 73% for 3 days with Bacillus sp. TKU004 (Wang et al. 2006). Also, the shrimp shells were deproteinized by 75% and 87% at 30°C for 6 days with Candida parapsilosis and Pseudomonas maltophilia, respectively (Chen 2001). 

The following 0-methylaldoses have been isolated from, or identified as constituents of, natural products 3-0-methylxylose (in the extracellular mucilage from the red alga Rhodella maculata), 3-0-methyl-L-xylose (together with L-xylose and L-rhamnose from the lipopolysaccharide of Pseudomonas maltophilia), 3-0-methy]-D-ribose (from the extracellular polysaccharide of a Cowpea strain of slow-growing Rhizobium, strain CB 756), 2-0-methyl- and 2,4-di-O-methyl-L-rhamnose (in the antibiotics steffimycin and steffimycin B produced by Strepto-myces steffisburgensis), and 3-0-methyl-galactose and -mannose (from the haemocyanin of snails). ...
