Penicillium fellutanum

Properties of pectinesterase from Penicillium fellutanum Biourge and new developments in pectin applications... [Pg.947]

Some properties of Penicillium fellutanum pectinesterase were studied. The optimum of pectinesterase action was detected at pH 5 and 45 °C. The enzyme was stable at pH 4 — 5 and 40 °C (pH 5) for 240 min. and was specific towards lemon pectin. An enzyme preparation composed mainly of pectinesterase was partially purified by gel filtration. Pectinesterase activity was accumulated in one of the obtained fractions. Molecular weights of fraction determined were found to be 46,000 and 1,200. Disk electrophoresis in polyacrilamide gel of the purified preparation revealed two protein bonds with one active component. The partially purified enzyme had the kinetic characteristics =... [Pg.947]

Subject of the present message is study of the conditions for Penicillium fellutanum cultivation (that is a producer of pectinesterase) and analysis of some properties of pectinesterase enzymatic preparation. [Pg.947]

Enzymatic preparation with predominant content of pectinesterase (obtained from Penicillium fellutanum culture liquid by isolation by acetone was purified. Primary enzymatic preparation was re — precipitated by three volumes of ethyl alcohol and centrifuged (6000 rev/min.) during 20 min. The obtained precipitate of partially purified pectinesterase preparation was dried in vacuum — desiccator. Sephadexes G — 50, G-75, G-lOO, G-200 "LKB" (Sweden) and Toyopearl HW-55 (Japan) were used for separation of enzymatic complex by gel — filtration. [Pg.948]

Kathiresan et al. (2009) reported the biosynthesis of silver nanoparticles using AgNOj as a substrate by Penicillium fellutanum isolated from coastal mangrove sediment. The biosynthesis was faster within minutes of silver ion coming in contact with the cell filtrate and was maximum when the culture filtrate was treated with... [Pg.328]

Possible okaramine precursors, i.e. cyclo (Trp-Trp) (20), cyclo (2-(reverse-prenyl)-Trp-Trp) (21), cyclo ( -(reverse-prenyty-Trp-Trp) (22), cyclo (2-(reverse-prenyl)-Trp-2 -(reverse-prenyl)-Trp) (23), and cyclo (7V1-(reverse-prenyl)-Trp-2 -(reverse-prenyl)-Trp) (24), were isolated during the course of the investigation of okaramine congeners [21]. Three of these compounds, 21, 22, and 24, are new compounds. cyclo(2-(Reverse-prenyl)-Trp-2 -(reverse-prenyl)-Trp) (23) was synthesized by Schkeryantz and coworkers as a precursor of gypsetin [24], but it was isolated for the first time from natural sources in our study. One year after our findings, Kozlovsky and coworkers reported the isolation of fellutanines A, B, C, and D from Penicillium fellutanum [25], which were found identical to the compounds 20, 22, and 23, respectively. [Pg.562]

Culture of the species Penicillium fellutanum, also collected from the digestive system of fish [Apogon endeka-taenia) caught in Japan, resulted in two cytotoxic peptides. [Pg.558]
