Abstract
Trichosporon yeasts are widely employed to produce lipids, lipases, and aspartic peptidases, but there are no previous studies on collagenase production. This work aimed to select the best collagenase producing Amazonian Trichosporon strains. Moreover, a 23-full factorial design (FFD) and a 22-central composite design combined with Response Surface Methodology were applied to optimize production and find the best conditions for hydrolysis of type I bovine collagen. Most of the studied strains had some collagenolytic activity, but the selected one achieved the highest value (44.02 U) and a biomass concentration of 2.31 g/L. The best collagenase production conditions were 160 rpm of agitation, pH 5.5 and a substrate concentration of 4.0 g/L. The former experimental design showed that substrate concentration was the only statistically significant factor on both biomass concentration and collagenase activity, while the latter showed simultaneous effects of substrate concentration and pH on collagenolytic activity, which peaked at pH 5.5-6.4 and substrate concentration of 3.0-3.4 g/L. An additional 2³-FFD was finally used to optimize the conditions collagen hydrolysis, and pH 6, 25 °C and a substrate concentration of 7.5 (g/L) ensured the highest hydrolysis degree. This study is the first that describes optimized conditions of collagenase production by Trichosporon strains.

Abstract
A highly enantioselective lipase from Tsukamurella tyrosinosolvents E105 was purified via ultrasonic extraction, precipitation, and chromatographic steps. The enzyme was purified about 38-fold with the recovery yield of 9 % and was confirmed as a dimer protein consisting of two identical subunits with a molecular mass of 24 kDa. The purified lipase was used to catalyze resolution of racemic ethyl 2-(2-oxopyrrolidin-1-yl) butyrate to (S)-2-(2-oxopyrrolidin-1-yl) butyric acid. The maximum activity of such lipase was obtained at pH 7.5, 35 °C, and the highest relative activity (156.80 %) was observed in the presence of 0.5 mM Co2+. Subsequently, the lipase was encapsulated within a mixture of 3 % sodium alginate and 0.8 % carrageenan, and then cross-linked with 0.6 % glutaraldehyde to enhance its biocatalytic capability and stability. Comparing with 36.9 % product yield and 97.5 % product ee of free lipase, the highest product yield of 46.3 % and ee of 98.5 % for immobilized lipase were achieved with the presence of 20 mM substrate. In addition, the reusability of immobilized lipase was also investigated, which could maintain 63.7 % of its initial conversion yield after seven repeated batch reactions. Thus, the evaluated enantioselective lipase in this work has a good potential for further industrial application.

Abstract
The cell-bound lipase from Rhizopus chinensis CCTCC M201021 with high catalysis ability for ester synthesis was located as a membrane-bound lipase by the treatments of Yatalase firstly. In order to improve its synthetic activity in non-aqueous phase, the pretreatments of this enzyme with various organic solvents were investigated. The pretreatment with isooctane improved evidently the lipase synthetic activity, resulting in about 139% in relative synthetic activity and 115% in activity recovery. The morphological changes of mycelia caused by organic solvent pretreatments could influence the exposure of the membrane-bound enzyme from mycelia and the exhibition of the lipase activity. The pretreatment conditions with isooctane and acetone were further investigated, and the optimum effect was obtained by the isooctane pretreatment at 4 degrees C for 1 h, resulting in 156% in relative synthetic activity and 126% in activity recovery. When the pretreated lipases were employed as catalysts for the esterification production of ethyl hexanoate in heptane, higher initial reaction rate and higher final molar conversion were obtained using the lipase pretreated with isooctane, compared with the untreated lyophilized one. This result suggested that the pretreatment of the membrane-bound lipase with isooctane could be an effective method to substitute the lyophilization for preparing biocatalysts used in non-aqueous phase reactions.

Abstract
An isolated strain of Bacillus subtilis identified by 16S rDNA sequence analysis produces an enantioselective ester hydrolase. Whole cells of B. subtilis (RRL BB1) and enzyme derived from it was capable of enantioselective hydrolysis of several racemates including drug intermediates with moderate to high enantioselectivity as already reported by us. In this communication, we describe cloning of the gene encoding the enantioselective esterase designated as estBB1. The primary structure of the enzyme determined from the nucleotide sequence indicated that esterase estBB1 has Mw approximately 52kDa and pI approximately 5.2 and belongs to the family of type B carboxylesterases with 50-60% similarity at amino acid level. Alignment studies of sequences of the estBB1 and Pnb esterase 56C8 from B. subtilis showed that estBB1 has an alpha/beta hydrolase fold with catalytic triad formed by Ser190, Glu305 and His394 at active site and Ser190 is located in the conserved motif -G-X-S-X-G-.

Abstract
An esterase (EC 3.1.1.1) produced by an isolated strain of Bacillus subtilis RRL 1789 exhibited moderate to high enantioselectivity in the kinetic resolution of several substrates like aryl carbinols, hydroxy esters, and halo esters. The enzyme named as B. subtilis esterase (BSE), was purified to >95% purity with a specific activity of 944 U/mg protein and 12% overall yield. The purified enzyme is approximately 52 kDa monomer, maximally activity at 37 degrees C and pH 8.0 and fairly stable up to 55 degrees C. The enzyme does not exhibit the phenomenon of interfacial activation with tributyrin and p-nitrophenyl butyrate beyond the saturation concentration. The enzyme showed preference for triacyglycerols and esters of p-nitrophenol with short chain fatty acid. Presence of Ca2+ ions increases the activity of enzyme by approximately 20% but its presence does not have any influence on the thermostability of the enzyme. The enzyme is not a metalloprotein and belongs to the family of serine proteases. The N-terminal amino acid sequence of BSE determined, as Met-Thr-Pro-Glu-Iso-Val-Thr-Thr-Glu-Tyr-Gly- revealed similarity with the N-terminal amino acid sequence of p-nitrobenzylesterase of B. subtilis.
