Endo and exoglucanases produced by Penicillium citrinum isolated from Amazon
Background Cellulolytic enzymes (glucohidrolases EC 3.2.1.-) are biocatalizators highly specific. They act in synergy to hydrolyze b-1,4 bonds between monosaccharide units of D-glucose in the cellulose chain releasing its constituents. Cellulases are categorized according to the place they act in the cellulosic fiber. Endoglucanases start hydrolysis, exoglucanases act in the reduced terminal pr...
متن کاملPurification of endoglucanase produced by Penicillium citrinum isolated from Amazon
Background The cellulolytic enzyme complex has many important biotechnological applications such as beverage, textile, food, paper and cellulose industries, as well as in degradation of lignocellulosic for ethanol biofuel production [1]. According to the enzymatic activity, cellulolytic complex is subdivided in three classes: endoglucanases, exoglucanases and b-D-glycosidases. Endoglucanases (e...
متن کاملDihydroisocoumarins from the Mangrove-Derived Fungus Penicillium citrinum
Three new dihydroisocoumarin penicimarins G-I (1-3), together with one known dihydroisocoumarin (4) and three known meroterpenoids (5-7), were obtained from a fungus Penicillium citrinum isolated from the mangrove Bruguiera sexangula var. rhynchopetala collected in the South China Sea. Their structures were elucidated by the detailed analysis of spectroscopic data. The absolute configuration of...
متن کاملQuinolactacins A1 and A2, new acetylcholinesterase inhibitors from Penicillium citrinum.
Alzheimer disease is a neurodegenerative disorder that is the most commoncause of dementia amongthe elderly. The neurophathological evidences have demonstrated that cholinergic functions declined in the basal forebrain and cortex in senile dementia of the Alzheimer type1>2). Accordingly, enhancement of cholinergic neurotransmission have been considered as one potential therapeutic approach agai...
متن کاملCitrinin derivatives from the marine-derived fungus Penicillium citrinum.
Three new citrinin derivatives, penicitrinols C, D, and E (1-3), along with two known compounds, citrinin (4) and decarboxydihydrocitrinone (5), were isolated from Penicillium citrinum. Their structures were determined by spectroscopic methods and X-ray diffraction analysis. Compounds 1 and 3 demonstrated weak cytotoxicity against the HL-60 cell line.
