Novel carotenoid oxidase involved in biosynthesis of 4,4'-diapolycopene dialdehyde.
Biosynthesis of C(30) carotenoids is relatively restricted in nature but has been described in Staphylococcus and in methylotrophic bacteria. We report here identification of a novel gene (crtNb) involved in conversion of 4,4'-diapolycopene to 4,4'-diapolycopene aldehyde. An aldehyde dehydrogenase gene (ald) responsible for the subsequent oxidation of 4,4'-diapolycopene aldehyde to 4,4'-diapoly...
متن کاملCarotenoid Biosynthesis in Fusarium
Many fungi of the genus Fusarium stand out for the complexity of their secondary metabolism. Individual species may differ in their metabolic capacities, but they usually share the ability to synthesize carotenoids, a family of hydrophobic terpenoid pigments widely distributed in nature. Early studies on carotenoid biosynthesis in Fusariumaquaeductuum have been recently extended in Fusarium fuj...
متن کاملIsolation and identification of 4, 4'-diapolycopene-4,4'-dioic acid produced by Bacillus firmus GB1 and its singlet oxygen quenching activity.
We succeeded in purifying the carotenoid produced by Bacillus firmus GB1 using chromatography on polystyrenic synthetic adsorbents, and identified it as 4,4'-diapolycopene-4,4'-dioic acid by HRESI-MS and NMR analyses of it and its dimethylester. In addition, we clarified the singlet oxygen (¹O₂) quenching activities of 4,4'-diapolycopene-4,4'-dioic acid and its methyl esters (mono and dimethyl ...
متن کاملisolation and identification of local bacillus isolates for xylanase biosynthesis.
background and objectives: bacillus species are attractive industrial organisms due to their rapid growth rates leading to a short fermentation cycle and for their capacity to secrete important enzymes and proteins such as xylanase into the extracellular medium. considering the industrial importance of xylanase, in this current study, bacillus spp. were isolated from different soils and were sc...
متن کاملIdentification of novel indigenous Bacillus thuringiensis isolates.
Internally Transcribed Spacers (ITS) characterization and distribution of Repetitive Extragenic Palindromic (REP) sequences were studied in the genome of 223 field isolates of Bacillus thuringiensis from Madurai, India. They were characterized by morphological, biochemical and molecular methods. One hundred and twenty four of a total 223 isolates fitted ITS characterization of B. thuringiensis ...
