“…Because it is a mushroom that is easier to cultivate, has abundant production, and is already traditionally used in the Yanomami feeding, L. crinitus has the potential to be studied and also consumed in a commercial production and form. As a fungus that grows on wood, the main studies related to the species address its role in the degradation of cellulose by enzymes, proteases, and laccases (Machado et al, 2016;Conceição et al, 2017;Santana et al, 2018), as well as as a competitive fungus with pathogenic fungi (e.g. Fusarium spp.)…”

Bromatological aspects of Lentinus crinitus mushroom (Basidiomycota: Polyporaceae) in agroforestry in the Cerrado

Much of the diversity of mushrooms is still unknown to science. On the search for new edible mushrooms, we began to look at the traditions of Amazonian forest peoples in order to learn about the potential for edible mushrooms among other species. On particular, the Yanomami people launched the encyclopedia of food (Sanoma) in 2016 to preserve their knowledge of their own food. They demonstrated how food production can be balanced with the forest and present dozens of mushrooms that are consumed by their communities. On view of the above information, the objective of this work is to present bromatological aspects of the Lentinus crinitus mushroom from an agroforestry homegarden in the Cerrado. The specimen was collected from an agroforestry homegarden with biome forest species and agronomic species, located in the Brazilian Cerrado, in the city of Goiânia, Goiás. L. crinitus mushrooms presented 61% humidity, containing 14% crude protein, 1.5% ether extract, 26% crude fiber, and 3.4% mineral matter. Ots bromatological characteristics are similar to others of commercial fungi. There is great potential for the use of the Lentinus crinitus mushroom in agroforestry yards in the Brazilian Cerrado, reconciling environmental conservation with the diversification of the production of agroextractive products.

Fungal cocultures can promote complex interactions that result in physiological and biochemical alterations that favor the synergic and more efficient action of extracellular enzymes such as laccase. Thus, coculture can be used as a strategy to increase enzymatic activity, dye degradation, and bioremediation of textile effluents. This study aimed to evaluate the coculture effect of Lentinus crinitus, Pleurotus ostreatus, Pycnoporus sanguineus, and Trametes polyzona on laccase activity, mycelial biomass production, and in vitro decolorization of azo, anthraquinone, and triphenylmethane dyes. The species were cultivated in liquid medium in monoculture and coculture in paired combinations for 15 days to determine the laccase activity and produced mycelial biomass. The enzymatic extracts of fungal cultivations were used in decolorization tests of reactive blue 220 (RB220), malachite green (MG), and remazol brilliant blue R (RBBR). Pleurotus-Trametes, Lentinus-Pleurotus, and Lentinus-Trametes cocultures increase laccase activity compared to respective monocultures. Lentinus-Pycnoporus, Lentinus-Trametes, Lentinus-Pleurotus, and Pleurotus-Trametes cocultures stimulate mycelial biomass production in relation to their respective monocultures. The enzymatic extracts of monocultures and cocultures promoted the decolorization of all dyes. RB220 dye presented fast decolorization. In 24 h, all extracts reached maximum decolorization and the greatest color reduction percentage was 90% for Pleurotus-Trametes coculture extract. Pleurotus-Trametes extract also increased the decolorization of MG and RBBR dyes when compared to their respective monocultures in 48 h and 72 h, respectively. However, RBBR dye presented the greatest resistance to decolorization.

“…(Basidiomycota) is a white-rot fungus with pantropical occurrence that grows in decaying wood GIBERTONI, 2006). It is known to produce enzymes of biotechnological interest such as laccase (VALLE et al, 2014;SANTANA et al, 2018), cellulase, and xylanase (CAMBRI et al, 2016) under different cultivation systems (MARIM et al, 2018). Its ability to decolorize dyes (ALMEIDA et al, 2018) and produce antioxidant compounds (UMEO et al, 2015) was also reported.…”

Fungi are capable of sensing light from ultraviolet to far-red and they use light as a source of information about the environment anticipating stress and adverse conditions. Lentinus crinitus is a lignin-degrading fungus which produces laccase and other enzymes of biotechnological interest. The effect of blue light on fungal enzymatic activity has been studied; however, it has not been found studies on the effect of the blue light on carbohydrate-active enzymes and on mycelial biomass production of L. crinitus. We aimed to investigate carbohydrate-active enzymes activity and mycelial biomass production of L. crinitus cultivated under continuous illumination with blue light. L. crinitus was cultivated in malt extract medium in the dark, without agitation, and under continuous illumination with blue light-emitting diodes. The blue light reduced the total cellulase, pectinase and xylanase activities but increased the endoglucanase activity. Blue light reduced the mycelial growth of L. crinitus in 26% and the enzymatic activity-to-mycelial biomass ratio (U mg-1 dry basis) increased in 10% total cellulase, 33% endoglucanase, and 16% pectinase activities. Also, it is suggested that L. crinitus has a photosensory system and it could lead to new process of obtaining enzymes of biotechnological interest.
