Bismuth Subsalicylate. (2-Hydroxybenzoato-0 )-oxobismuth [14882-18-9] (Pepto-Bismol) maybe made by the process described in Reference 10. Bismuth subsaHcylate has been shown to bind toxins produced by several bacterial strains. It may also act as a result of its saHcylate component on prostaglandin formation and have specific intestinal antisecretory activity. It has been found to be effective in the prevention and therapy of... 

Other Microbial Systems. In addition to the systems described, gene cloning is routinely performed in several other bacterial strains including Streptoccocus Staphylococcus Brevibacterium BJdodobacter Comyebacterium Glucanobacter Acetobacter and Zanthomonas species. 

Certain bacterial strains convert propylene glycol to pymvic acid in the presence of thiamine (15) other strains do the conversion without thiamine (16). Propylene oxide is the principal product of the reaction of propylene glycol over a cesium impregnated siHca gel at 360°C in the presence of methyl ethyl ketone and xylene (17). 

Other bacterial strains identified as biodegrading poly(vinyl alcohol) iaclude Flavobacterium (95) 2in.dFicinetobacter (96) and many others, as well as fungi, molds, and yeasts (97). Industrial evaluations at Du Pont (98) and Air Products (99) iadicate that over 90% of poly(vinyl alcohol) entering wastewater treatment plants is removed, and hence no environmental pollution is likely. 

H-Dealkylation. This is commonly observed as a primary transformation of pesticides with A/-alkyl substituents, such as atrazine [1912-24-9] (3) (eq. 5), trifluraHn [1582-09-8] (4) (eq. 6) (16), and 3 -ethyl dipropylthiocarbamate [759-94-4] (EPTC) (5) (eq. 7) (18). These reactions are catalyzed by a variety of bacterial strains, including Noeardia, Pseudomonas, Phodococcus, and Streptomyces. 

Subsequently, other structural variations were reported encompassing compounds such as PS-5 (5) (5), carpetimycin A (6) (6), asparenomycin A (7) (7), and pluracidomycin A (8) (8), from a wide variety of streptomycete strains. Following these stmctures the simplest member of the series, having the completely unsubstituted nucleus, (1, X = CH2), was isolated from bacterial strains of Serratia and Ervinia (9). AH other natural products reported have substituents at both the C-6 and C-2 positions of the bicycHc ring system. Differences in the nature and stereochemistry of these substituents has provided a wide variety of stmctures, and over forty variations have been reported and comprehensively Hsted (10).

Bacillus thuringiensis produces a variety of organic compounds which are toxic to the larvae of certain susceptible insect hosts. Among the toxic entities are proteinaceous crystals, probably three soluble toxins, and certain enzymes. The protein material is the major toxin active in killing lepidopterous larvae. The protein is formed by the cells apparently in close synchrony with sporulation, and its nature is a constant function of bacterial strain. The mode of action of the protein is under study. The sequence of events in the pathology observed is probably solubilization of the crystal (enzymatic or physical)—>liberation of toxic unit—>alteration of permeability of larval gut wall— change in hemolymph pH—>invasion of hemolymph by spores or vegetative cells of the bacterium. 

For example, a screening of 416 strains (71 bacterial strains, 45 actinomycetes, 59 yeast, 60 basidiomycetes, 33 marine fungi, and 148 filamentous fungi) has been performed to look for microorganisms that display reductase activity in the absence of oxidase activity [8b]. A new microorganism, Diplogdasinospora grovesii IMI... 

Extensive screening methodology was used to find the suitable microorganism. As a result, K. pneumoniae IFO 3319 out of 450 bacterial strains was found to give the corresponding (2J, 3S)-hydroxy ester with 99% de and >99% ee in kilogram scale quantitatively [29g]. 

Since 1925, PHAs were the first biomaterial, discovered by the French microbiologist, M. Lemoigne, accumulated as intracellular substance in a bacterial strain of Bacillus... 

Recombinant resilin production was induced, with the nonmetabolizable lactose analogue IPTG, in the Escherichia coli bacterial strain BL21(DE3)/pLysS. Cells were collected by centrifugation (10,000 g, 20 min at 4°C) and the cell pellet frozen at 80°C. 

The refractory nature of some pollutants, notably, persistent polyhalogenated compounds, has raised problems of bioremediation of contaminated sites (e.g., sediments and dumping sites). There has been interest in the identification, or the production by genetic manipulation, of strains of microorganisms that can metabolically degrade recalcitrant molecules. For example, there are bacterial strains that can reductively dechlorinate PCBs under anaerobic conditions. 

Activities are expressed as minimum inhibitory concentration (MIC, pg mL ) defined as the lowest concentration required for complete inhibition of growth of bacterial strain.

A bacterial strain BN6 oxidizes 5-aminonaphthalene-2-sulfonate by established pathways to 6-amino-2-hydroxybenzalpyruvate that undergoes spontaneous cyclization to 5-hydroxy-quinoline-2-carboxylate (Figure 2.2a) (Nortemann et al. 1993).

The transport of EDTA into a bacterial strain capable of its degradation has been examined (Witschel et al. 1997). Inhibition was observed with DCCD (ATPase inhibitor), nigericin (dissipates ApH), but not valinomycin (dissipates Av /), and was dependent on the stability constant of metal-EDTA complexes. 

A number of bacterial strains with monooxygenase activity have been described, and different types of MMO have played important roles in the degradation of a range of aliphatic componnds. MMO may exist in either a soluble (sMMO) form that has been more extensively studied or in a particulate (pMMO) form. These forms display different substrate ranges and different rates of transformation rates, and most methanotrophs express only the particnlate form of the enzyme (Hanson and Hanson 1996).
