Abstract: To investigate the simultaneous influence of different non-nutritional factors in production and physical-chemical characteristics of chitosan obtained by Syncephalastrum racemosum we used individually agroindustrial wastes as the only nutritional sources for fungus growth. The growth conditions were evaluated according to Factorial Design, 2 4 with three central points in order to determine the mainly factors for maximum production of microbiological chitosan in submerged culture. Syncephalastrum racemosum gr… Show more

“…The yield of chitosan obtained from the dry biomass of R. arrhizus was 22.53 mg of chitosan/g of fungus. This value is similar to the yield (26 mg/g) of chitosan obtained from the dry masses of the fungi, Syncephalastrum racemosum [55] and Pleurotus ostreatus (24 mg/g) [56], but lower than the yield (37.7 mg/g) obtained from the fungus, Agaricus bisporus [56].…”

“…Chitooligosaccharides and their derivatives are the appropriate agents capable of treating or preventing various chronic inflammation such colitis, hepatitis, gastritis, periodontal disease and through drug delivery systems [43][44][45]; (c) agricultural applications [46][47][48], and (d) bionanotechnology, such as the versatile potential uses in cosmetics, photography, ophthalmology, textile industry and water and waste treatment [49,50]. It has been also reported that large-scale chitosan commercialization originates from the chemical alkaline hydrolysis of shrimp chitin, with a cost of nearly USD 10/g (Sigma Chemical Con., St. Louis, MO 63118, USA) [51], but agro-industrial wastewaters have been also used as alternative media for fungi grown in submerged fermentation, which are readily available and have a low cost to use, saving around 38-73% of the total cost of the bioproduct production [51,52]. However, cost production is flexible since it includes transportation and labor costs, which vary significantly around the world [38].…”

“…In recent years, some studies have shown the potential of fungal chitosan, such as antifungal, antibacterial, anticancer and antiparasitic action (Paiva et al, 2014;Souza Neto et al, 2017;Almutairi et al, 2020;Batista et al, 2020;Sathiyaseelan et al, 2020). For these reasons, fungal chitosan is already being produced and marketed by companies in different countries, such as Belgium, Canada and the United States.…”
