Induction of pigment production through media composition, abiotic and biotic factors in two filamentous fungi

Abstract

HighlightsPigment production and accumulation is dependent of high C:N ratios in F. oxysporum and A. chevaleri.Red pigment content of F. oxysporum in terms of Absorbance units per gram of biomass increased in 191% through use of blue light. Different light wavelengths stimulate synthesis of additional pigments in A. chevalieri with highest accumulation in red and UV-light.Stimulation of pigment production in co-culture is species – specific, being only accomplished in A. chevalieri. With a rise higher that 500% of a pigment obtained in green light.

Influence of Different Light Regimes on the Mycoparasitic Activity and 6-Pentyl-α-pyrone Biosynthesis in Two Strains of Trichoderma atroviride

“…Accordingly, it has been shown that light increases fumonisin biosynthesis in Fusarium spp. [ 67 ] and that blue light triggers red pigment content of F. oxysporum [ 68 ].…”

Fungal Pigments and Their Prospects in Different Industries

“…Studies have reported that the induction or enhancement in pigment production was possible using co-culturing of fungi with bacteria or yeast, but it was species-specific. In case of Monascus and A. chevalieri, co-culturing was found to be effective, whereas in case of F. oxysporum, the results were negative [158,170]. Co-culturing of C. neoformans with Klebsiella aerogenes led to synthesis of melanin by the fungus, using dopamine synthesized by bacteria [171].…”

“…Most of the studies have shown that incubation in total darkness resulted in enhanced biomass and pigment production [152,155,156]. Studies have also reported that there is an enhancement in the pigment production in the case of A. alternata and M. ruber when exposed to blue and red light, respectively [156,157], and in F. oxysporum when exposed to blue and green light [158]. In contrast, reduction in biomass and pigment yield has been observed in I. farinosa, E. nidulans, F. verticillioides, P. purpurogenum (currently known as C. farinosa, A. nidulans, F. fujikuroi, T. purpureogenus, respectively), and M. purpureus when exposed to green and yellow light [155].…”

“…Optimization of pigment production by simultaneously altering the physical and chemical parameters has been explored by many investigators. Several studies have reported an enhancement of the yield of pigment and biomass from different fungal genera such as Monascus, Penicillium, Fusarium, Alternaria, etc., when the physical and chemical parameters were simultaneously altered [104,133,135,158,[160][161][162][163][164][165][166][167].…”

Enhancement of microbial pigment production from Monascus ruber by sodium octanoate addition

“…Natural pigments come from plants, animals and microorganisms, but few are available in amounts sufficient for commercial use as food and beverage formulations (Palácio-Barrera et al, 2019;Wójciak et al, 2011). The most common natural pigments are obtained from plants, namely carotenoids, chlorophylls, anthocyanins and betalains, but natural dyes can be produced from non-vegetable sources such as animals and microorganisms (Sánchez-Muñoz et al, 2020;Stachowiak, 2014).…”
