Abstract
- In this work, we propose the reuse of apple pomace as a substrate for fungal chitosan production by liquid cultivation of Gongronella butleri CCT4274. Different concentrations of reducing sugars and sodium nitrate were added to the aqueous extract of apple pomace and the best result was obtained with 40 g/L of reducing sugars and 2.5 g/L of sodium nitrate. The results indicate the possibility of producing 1.19 g/L of chitosan per liter of culture medium after 72.5 hours of cultivation, representing around 21% of the biomass content. Este trabalho propõe o reuso do bagaço de maçã como substrato para a produção de quitosana fúngica em cultivo liquido do fungo Gongronella butleri CCT4274. Diferentes concentrações de açúcares redutores e nitrato de sódio foram adicionadas ao extrato aquoso do bagaço de maçã. O melhor resultado foi obtido para concentrações de 40 g/L e 2,5 g/L de açúcares redutores e nitrato de sódio, respectivamente. Os resultados indicam a possibilidade de produzir 1,19 g/L de quitosana após 72,5 horas de cultivo, representando 21% da composição da biomassa.
