Effects of light intensity and light wavelength on the production of mycophenolic acid by Penicillium brevicompactum in batch cultures

Effects of light quality on the accumulation of oil in a mixed culture of Chlorella sp. and Saccharomyces cerevisiae

“…Basically the light intensity was highly dependent on the height of the bioreactor due to its unique design. 36 The light wavelength was measured using a light spectrometer (Ocean optics USB 650, Tainan, Taiwan).…”

“…33 Thus, a LED photobioreactor equipped with various LEDs could be a useful tool to investigate the effects of light on microorganisms. 36 Few studies in literature have been focused on the influence of light quality on the lipid content of microalgae in either monoculture or mixed cultures. Although mixed cultures of microalgae with other microorganisms have been adopted in wastewater treatment for nitrogen and phosphate removal, 37 astaxanthin production, 38 and pollutant removal, 39 little effort has been made on lipid accumulation.…”

Enhanced Production of Hypocrellin A in Submerged Cultures of Shiraia bambusicola by Red Light

“…It was reported that visible light from red to blue could stimulate the production of fumonisin B2 and B3 in Fusarium verticillioides (20). Red light-emitting diode (LED) light (630 nm) at 900 lx was used to stimulate mycophenolic acid production in Penicillium brevicompactum cultures in a bubble column photobioreactor to 0.56 g L À1 , an 87% increase to that in the dark condition (21). These studies suggested a novel approach using light control strategy for bioactive metabolite production in mycelium cultures.…”

Production of mycophenolic acid by Penicillium brevicompactum—A comparison of two methods of optimization

“…In submerged batch fermentations, low-intensity pulsed ultrasound has enhanced the production of MPA by P. brevicompactum [18] . Production in this fungus may also be influenced by the intensity and wavelength of the prevailing light [19] , although most commercial submerged fermentations are inevitably conducted in the dark. Production of MPA by solid-state fermentation has been extensively reported in literature [7] , [20] , [21] , but solid state fermentations are generally not used for the commercial production of medicinal products.…”
