Abstract
Sphingorhabdus sp. YGSMI21, a novel microbial strain with an enantioselective epoxide hydrolase activity, was isolated from tidal samples contaminated by accidental oil spills subjected to enriched culture with polycyclic aromatic hydrocarbon. This strain was able to optically decompose (R)-styrene oxide (SO) and showed 100% optical purity. In addition, it showed a good enantioselectivity for the derivatives of (S)-SO, (S)-2-chlorostyrene oxide (CSO), (S)-3-CSO and (S)-4-CSO. For (S)-2-CSO, (S)-3-CSO and (S)-4-CSO, 99.9%ee was obtained with the yield of 26.2%, 24.8%, and 11.0%, respectively, when using 10 mg cells of Sphingorhabdus sp. YGSMI21 at pH 8.0 with 4 mM racemic substrates at pH 8.0 and 25°C. The values obtained in this study for (S)-2-CSO, particularly the yield of 26.2%, is noteworthy, considering that obtaining an enantiomerically pure form is difficult. Taken together, Sphingorhabdus sp. YGSMI21 can be regarded as a whole-cell biocatalyst in the production of various (S)-CSO with the chlorine group at a different position.

Abstract
A novel epoxide hydrolase (EHase) from polycyclic aromatic hydrocarbon (PAH)-degrading bacteria was identified and characterized. EHase activity was identified in four strains of PAH-degrading bacteria isolated from commercial gasoline and oil-contaminated sediment based on their growth on styrene oxide and its derivatives, such as 2,3- and 4-chlorostyrene oxides, as a sole carbon source. Gordonia sp. H37 exhibited high enantioselective hydrolysis activity for 4-chlorostyrene oxide with an enantiomeric ratio of 27. Gordonia sp. H37 preferentially hydrolyzed the (R)-enantiomer of styrene oxide derivatives resulting in the preparation of a (S)-enantiomer with enantiomeric excess greater than 99.9 %. The enantioselective EHase activity was identified and characterized in various PAH-degrading bacteria, and whole cell Gordonia sp. H37 was employed as a biocatalyst for preparing enantiopure (S)-styrene oxide derivatives.

Abstract
As a continuous effort of developing highly enantioselective epoxide hydrolase from marine microorganisms, it was found that Maritimibacter alkaliphilus KCCM 42376 [corrected] was highly enantioselective toward racemic glycidyl phenyl ether (GPE). An open reading frame (ORF) encoding a putative epoxide hydrolase (EHase) was cloned from the genome of Maritimibacter alkaliphilus KCCM 42376 [corrected], followed by expression and purification in Escherichia coli. The purified EHase (REH) hydrolyzed (S)-GPE preferentially over (R)-GPE. Enantiopure (R)-GPE from kinetic resolution of 29.2 mM racemic GPE using the purified REH could be obtained with enantiopurity of more than 99.9% enantiomeric excess (ee) and 38.4% yield (theoretical, 50%) within 20 min (enantiomeric ratio (E-value): 38.4). The enantioselective activity of REH toward GPE was also confirmed by the analysis of the vicinal diol, 3-phenoxy-1,2-propanediol. To our knowledge, this study demonstrates the highest enantioselective resolution of racemic GPE using a purified biocatalyst among the known native EHases.

Abstract
To develop an enantioselective epoxide hydrolase (EHase) from marine microorganisms, marine samples were collected from a variety of marine environments. Strains isolated by the capability of living on styrene oxide (SO) were screened for retaining enantioselective EHase activities toward SO by combining spectrophotometric, GC, and HPLC analysis. Consequently, one strain, JCS358, was selected, and the sequence analysis of 16S rRNA gene showed that the strain belonged to Erythrobacter cluster. Twelve additional Erythrobacter strains from this study or acquired from culture collections were thereby tested for displaying EHase activities, and most of tested strains showed enantioselective hydrolysis toward SO and glycidyl phenyl ether. Kinetic resolution of racemic SO using whole cell of Erythrobacter sp. JCS358 was performed. Enantiopure (S)-SO could be obtained with an enantiomeric excess (ee) higher than 99% after 15 h incubation. The determination of 1-phenyl-1,2-ethanediol configuration derived from racemic SO confirmed the enantioselective hydrolyzing activity of Erythrobacter sp. JCS358.

Abstract
The 1-oxaspiro[2.5]octane moiety is a common motif in many biologically active spiroepoxide compounds. Stereochemistry plays an important role in the action of these spiroepoxides, since the O-axial C3 epimers are predominantly responsible for biological activity. In view of this, the reactivity of the yeast epoxide hydrolase (YEH) from Rhodotorula glutinis towards both O-axial and O-equatorial C3 epimers of various 1-oxaspiro[2.5]octanes was investigated. O-axial C3 Epimers were hydrolyzed faster than the O-equatorial C3 epimers. The stereochemical preference was greatly dependent on the type of substitution on the cyclohexane ring. The preference of YEH for O-axial C3 epimers, found throughout this study, illustrates the effectiveness of YEH in enzymatic detoxification of spiroepoxides.

Abstract
An epoxide hydrolase gene of about 0.8 kb was cloned from Rhodococcus opacus ML-0004, and the open reading frame (ORF) sequence predicted a protein of 253 amino acids with a molecular mass of about 28 kDa. An expression plasmid carrying the gene under the control of the tac promotor was introduced into Escherichia coli, and the epoxide hydrolase gene was successfully expressed in the recombinant strains. Some characteristics of purified recombinant epoxide hydrolase were also studied. Epoxide hydrolase showed a high stereospecificity for L: (+)-tartaric acid, but not for D: (+)-tartaric acid. The epoxide hydrolase activity could be assayed at the pH ranging from 3.5 to 10.0, and its maximum activity was obtained between pH 7.0 and 7.5. The enzyme was sensitive to heat, decreasing slowly between 30 degrees C and 40 degrees C, and significantly at 45 degrees C. The enzyme activity was activated by Ca(2+) and Fe(2+), while strongly inhibited by Ag(+) and Hg(+), and slightly inhibited by Cu(2+), Zn(2+), Ba(2+), Ni(+), EDTA-Na(2) and fumarate.

Abstract
Deoxynivalenol (DON) transformation products from selected time course experiments were analyzed by thin-layer chromatography. With the strainAlternaria alternata f. sp.lycopersici AS27-3, one major metabolite of DON in ethyl acetate was observed. This unidentified metabolite was more polar than DON and has a Rf value of 0.71. Derivatization indicated that this metabolite was probably an unidentified trichothecene. Screening of 29 other microbial isolates (bacteria, yeast, filamentous fungi) for DON transformation did not result in any active organism.

Abstract
Epoxide hydrolase activity was produced during the exponential and stationary growth phases of the fungus Beauveria bassiana ATCC 7159. It was completely cell-associated. After cell disruption epoxide hydrolase activity was recovered in both the cell debris (EH "A") and the soluble fraction (EH "B"), but not in the membrane fraction. Activity assays of these fractions with two different substrates indicated that their substrate specificity, as well as the corresponding E value and, to a lesser extent, their regioselectivity, were different. Also, we could observe that the absolute configuration of the residual epoxide was opposite. This indicates that these two epoxide hydrolase activities are substantially different and are, therefore, interestingly complementary biocatalysts for the preparation of the corresponding epoxides and/or vicinal diols in nearly enantiopure form.

Abstract
The production of Alternaria alternata f. sp. lycopersici host-specific toxins (AAL toxins) and epoxide hydrolase (EH) activity were studied during the growth of this plant-pathogenic fungus in stationary liquid cultures. Media containing pectin as the primary carbon source displayed peaks of EH activity at day 4 and at day 12. When pectin was replaced by glucose, there was a single peak of EH activity at day 6. Partial characterization of the EH activities suggests the presence of three biochemically distinguishable EH activities. Two of them have a molecular mass of 25 kDa and a pI of 4.9, while the other has a molecular mass of 20 kDa and a pI of 4.7. Each of the EH activities can be distinguished by substrate preference and sensitivity to inhibitors. The EH activities present at day 6 (glucose) or day 12 (pectin) are concomitant with AAL toxin production.

Abstract
Epoxide hydrolases from bacterial and fungal sources are highly versatile biocatalysts for the asymmetric hydrolysis of epoxides on a preparative scale. Besides kinetic resolution, which yields the corresponding enantiomerically enriched vicinal diol and the remaining nonconverted epoxide, enantioconvergent processes are also possible, which lead to the formation of a single enantiomeric diol from a racemic oxirane. The data available to date indicate that the enantioselectivities of enzymes from certain microbial sources can be correlated to the substitutional pattern of various types of substrates: red yeasts (e.g. Rhodotorula or Rhodosporidium sp.) give best enantioselectivities with monosubstituted oxiranes; fungal cells (e.g. from Aspergillus and Beauveria sp.) are best suited for styrene oxide-type substrates; bacterial enzymes, on the other hand (in particular from Actinomycetes such as Rhodococcus and Nocardia sp.) are the biocatalysts of choice for more highly substituted 2,2- and 2,3-disubstituted epoxides.

Abstract
A highly enantioselective, soluble epoxide from Nocardia sp. EH1 was purified to homogeneity via a four-step procedure: (i) hydrophobic interaction chromatography on Phenyl Sepharose CL-4B, (ii) anion exchange chromatography on SOURCE 30Q, followed by (iii) a second hydrophobic interaction chromatography on Phenyl Sepharose HP, and finally (iv) gel-filtration on Superdex 75 HR 10/30. The pure protein was shown to be a monomer of integral of 34 kDa possessing an optimum pH of 8-9. Neither UV-absorbing cofactors nor metal ions were required for activity. In contrast to whole-cell activity, the partially purified enzyme proved to be considerably less stable. Stabilization was achieved by addition of non-ionic detergents such as Tween 80 or Triton X-100, causing a shift of the temperature optimum from 35 to 40 degrees C. Both effects combined led to an enhancement of the relative activity of up to approximately 150% of that of the native enzyme.
