Characterization of a Highly Thermostable and Organic Solvent-Tolerant Copper-Containing Polyphenol Oxidase with Dye-Decolorizing Ability from Kurthia huakuii LAM0618T
Laccases are green biocatalysts that possess attractive advantages for the treatment of resistant environmental pollutants and dye effluents. A putative laccase-like gene, laclK, encoding a protein of 29.3 kDa and belonging to the Cu-oxidase_4 superfamily, was cloned and overexpressed in Escherichia coli. The purified recombinant protein LaclK (LaclK) was able to oxidize typical laccase substra...
متن کاملDraft Genome Sequence of Kurthia huakuii LAM0618T, an Organic-Pollutant-Degrading Strain Isolated from Biogas Slurry
Kurthia huakuii LAM0618(T) is a facultative anaerobic pollutant-degrading bacterium isolated from biogas slurry. An analysis of the draft genome sequence of LAM0618(T) reveals a genome size of 3,585,165 bp, with a mean G+C content of 39.1%. The genome contains 3,560 coding sequences and 112 tRNA and 33 rRNA genes.
متن کاملPurification and Characterization of a Novel Laccase from Cerrena sp. HYB07 with Dye Decolorizing Ability
Laccases (EC 1.10.3.2) are a class of multi-copper oxidases with important industrial values. A basidiomycete strain Cerrena sp. HYB07 with high laccase yield was identified. After cultivation in the shaking flask for 4 days, a maximal activity of 210.8 U mL(-1) was attained. A 58.6-kDa laccase (LacA) with 7.2% carbohydrate and a specific activity of 1952.4 U mg(-1) was purified. 2,2'-Azino-bis...
متن کاملProduction And Partial Characterization Of a Thermostable, Alkaline And Organic Solvent Tolerant Lipase From Trichoderma atroviride 676
The several industrial applications of lipases have stimulated interest in isolation of new enzymes from novel sources. In this study, the lipase production from Trichoderma atroviride 676 was optimized by statistical design methods. The response surface methodology based on 3(3-1) fractional factorial, showed that the yeast extract and MgSO4 played a significant role on lipase production, yiel...
متن کاملOrganic-Solvent and Surfactant Tolerant Thermostable Lipase, Isolated from a Thermophilic Bacterium, Geobacillus thermodenitrificans IBRL-nra
Lipases (triacylglycerol acylhydrolase, EC 3.1.1.3), catalyze the hydrolysis of long-chain triglycerides with the formation of diacylglyceride, monoglyceride, glycerol and fatty acids. Lipases are actively used in various industries which include food and diary, pharmaceuticals, organic synthesis and detergent and cosmetics. Thermostable lipases are commercially significant for their potential ...
