The findings of the study demonstrate the impact of low-intensity laser and quasi-monochromatic light on the biosynthetic activity of the edible medicinal fungus L. edodes during submerged cultivation.<\/p>\n

\"\"<\/p>\n

An artificial lighting installation based on matrices of light-emitting diodes (LED) emitting light at 470\u00a0nm (blue), 530\u00a0nm (green), 650\u00a0nm (red), and argon gas laser (488\u00a0nm) was used.<\/p>\n

Irradiation with blue and red LED and laser led to a shortening of the lag phase by 2\u00a0days and an increase in the mycelial mass.<\/p>\n

Irradiation with laser light resulted in the highest mycelial mass yield (14.1\u00a0g\/L) on the 8th day of cultivation. Irradiation in all used wavelength ranges caused an increase in the synthesis of both extracellular and intracellular polysaccharides.<\/p>\n

Laser light at 488\u00a0nm and LED at 470\u00a0nm proved to be the most effective.<\/p>\n

Irradiation with red, green, and blue laser light caused an increase in the total amount of fatty acids in the mycelial mass compared to the control.<\/p>\n

A significant distinction in qualitative composition was observed: short-chain acids C6<\/sub>\u2012C12<\/sub>\u00a0compounds were produced under red light irradiation, whereas long-chain C20<\/sub>\u2012C24<\/sub>\u00a0were formed under green light irradiation.<\/p>\n

The most significant changes in the aromatic profile of the mycelial mass and culture liquid were recorded upon irradiation with green light. The content of aromatic components increased 24.6 times in the mycelial mass and 38.5 times in the culture liquid.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
