【摘要】 胶孢炭疽菌(Colletotrichumgloeosporioides)为一种丝状真菌,蓝光照射可诱导类胡萝卜素的积累。光镜下观察表明,蓝光可诱导胶孢炭疽菌菌丝积累色素颗粒,而黑暗和红光处理却无此现象。类胡萝卜素的积累受蓝光光照强度的影响。28℃且蓝光为6.5μmol.m-2.s-1时,类胡萝卜素积累量可随光照时间延长呈增长趋势,在第5天达到最高峰为71.8μg/g FW,随后含量下降。此外,胶孢炭疽菌在黑暗中预培养的时间也影响蓝光的诱导反应。更多还原

【Abstract】 Blue light induced carotenoid accumulation in filamentous fungus-Colletotrichum gloeosporioides. The pigment particles were observed in the fungal mycelium by microscope after blue light irradiation. The pigmentation was not found in the fungal mycelium either cultured under dark condition or cultured in red light. The accumulation of the carotenoid was regulated by blue light intensity. When C. gloeosporioides was incubated in blue light of 6.5μmol·m^-2.s^-1 under 28℃, carotenoid content increased with the irradiation time and reached to a peak of 71.8μg/g FW at 5d. The treatment of dark pre-culture of C. gloeosporioides also had effect on the production of the pigment induced by blue light.更多还原
