“…paradoxus is catabolically diverse, utilizing a wide range of naturally occurring compounds as sole growth substrates (1, 4, 6, 8, 12, 13, 15, 21, 24, 29-31, 34, 40, 49). Variovorax species have also been observed to degrade a variety of contaminants (5,19,37,41,42,46,(50)(51)(52), including the herbicide atrazine (41). The S110 genome contains an array of genes supporting similar metabolic diversity, although many of the pathways were incompletely identified.…”

“…This metabolic capacity suggests that Variovorax plays an essential role in the natural cycling of biogenic chemicals. Variovorax species are also able to degrade a variety of contaminants, including pesticides and crude oil-associated S-metabolites (5,19,37,41,42,46,50,51,52), often in synergistic and mutually beneficial interactions with other bacteria.

Variovorax paradoxus is a microorganism of special interest due to its diverse metabolic capabilities, including the biodegradation of both biogenic compounds and anthropogenic contaminants. V. paradoxus also engages in mutually beneficial interactions with both bacteria and plants. The complete genome sequence of V. paradoxus S110 is composed of 6,754,997 bp with 6,279 predicted protein-coding sequences within two circular chromosomes. Genomic analysis has revealed multiple metabolic features for autotrophic and heterotrophic lifestyles. These metabolic diversities enable independent survival, as well as a symbiotic lifestyle. Consequently, S110 appears to have evolved into a superbly adaptable microorganism that is able to survive in ever-changing environmental conditions. Based on our findings, we suggest V. paradoxus S110 as a potential candidate for agrobiotechnological applications, such as biofertilizer and biopesticide. Because it has many associations with other biota, it is also suited to serve as an additional model system for studies of microbeplant and microbe-microbe interactions.Variovorax paradoxus is a metabolically diverse, aerobic bacterium that engages in mutually beneficial interactions with a variety of bacteria and plants. V. paradoxus belongs to the subclass of Proteobacteria and can metabolically utilize natural compounds produced by other biota, such as acyl homoserine lactones (AHLs) (25) and alkyl/aryl-sulfonates (38). This metabolic capacity suggests that Variovorax plays an essential role in the natural cycling of biogenic chemicals. Variovorax species are also able to degrade a variety of contaminants, including pesticides and crude oil-associated S-metabolites (5,19,37,41,42,46,50,51,52), often in synergistic and mutually beneficial interactions with other bacteria. In addition, a close relative of Variovorax was found to be the central, nonphotosynthetic partner within the phototrophic consortium "Chlorochromatium aggregatum" (22). Moreover, V. paradoxus is resistant to various heavy metals, including cadmium and mercury (2).V. paradoxus belongs to a group referred to as plant growthpromoting rhizobacteria (PGPR), which exert beneficial effects on plant growth. As a common plant symbiont found in the rhizosphere (2, 3), the metabolic diversity of V. paradoxus appears to be related to its role as a PGPR. By degrading toxic contaminants, this bacterium can prevent harm otherwise experienced by the plant and thus can promote plant growth. Strains of Variovorax can enhance the host plant's stress tolerance and disease resistance (2, 3) and aid in nutrient availability and uptake (38). The effectiveness of Variovorax as a PGPR is likely to be more potent because it also appears to be a good endophytic symbiont (34,36,39,43,44,45,47) and thus interacts more closely with the host plant. Conversely, endospheric habitats are known to offer microbes the advantage of a more uniform and protective niche compared to the competitive, high-stress environment of the soil (36).The diverse metabol...

They are detected in body fl uids [46,110] and are known to induce bladder stone formation, irritation of skin, eyes, respiratory tract and blurred vision [20,21,103].

Phthalate isomers and their esters are used heavily in various industries. Excess use and leaching from the product pose them as major pollutants. These chemicals are toxic, teratogenic, mutagenic and carcinogenic in nature. Various aspects like toxicity, diversity in the aerobic bacterial degradation, enzymes and genetic organization of the metabolic pathways from various bacterial strains are reviewed here. Degradation of these esters proceeds by the action of esterases to form phthalate isomers, which are converted to dihydroxylated intermediates by specifi c and inducible phthalate isomer dioxygenases. Metabolic pathways of phthalate isomers converge at 3,4-dihydroxybenzoic acid, which undergoes either ortho-or meta-ring cleavage and subsequently metabolized to the central carbon pathway intermediates. The genes involved in the degradation are arranged in operons present either on plasmid or chromosome or both, and induced by specifi c phthalate isomer. Understanding metabolic pathways, diversity and their genetic regulation may help in constructing bacterial strains through genetic engineering approach for effective bioremediation and environmental clean up.

“…The enzymes hydrolyzing phthalic acid esters, which are potential environmental pollutants, may be one exceptional aryl-carboxylesterase studied in many research groups. [12][13][14][15][16] In addition, the aryl-carboxylesterases thus far reported appeared to have rather narrow substrate specificity, or the substrates studied with the enzymes are limited in structure, [7][8][9][10][11] when one considers the occurrence of a large number of structurally analogous arylcarboxylic acid esters. Enzymes hydrolyzing 4-hydroxybenzoic acid esters are considered to belong to a different esterase family from benzoyl esterases.…”

A novel esterase showing activity specific for esters of aryl-carboxylic acids was discovered in Sporosarcina sp. nov., which was identified by the 16S rDNA sequencing method in addition to morphological and physiological analyses. The aryl-carboxylesterase (named EstAC) was purified 780-fold from crude cell extracts by a 5-step procedure. EstAC was characterized as a monomeric protein with a molecular weight of 43,000, an optimum pH of around 9.0, and an optimum temperature of 40 C. The pH optimum and the effects of inhibitors together with an internal amino acid sequence suggested that EstAC is a member of family VIII esterases. EstAC was found to be highly active on a wide variety of substrates such as alkyl benzoates, alkyl phenylacetates, ethyl -or -substituted phenylpropionates, dialkyl terephthalates, dimethyl isophthalate, and ethylene glycol dibenzoate. However, monomethyl terephthalate was not hydrolyzed. It was suggested that EstAC had 4-hydroxybenzoyl and cinnamoyl esterase activities as well.
