Obtenção de quitosana fúngica crescida em meio alternativo constituído com farinha de carapaça de camarão.

Abstract

Shrimp farming is one of the highlights of the Brazilian economy, as regards the fish industry, in 2010 the marine shrimp farming in Brazil produced about 69 513 tonnes of shrimp this big production generates environmental impacts through the disposal of waste processing, especially heads and shells of crustaceans, which have low or no commercial value to shrimp producers, therefore, the need to seek new technologies and sustainable ways to mitigate environmental impacts caused by the shrimp industry is evident. Based on this, the carapace of dried and crushed prawn (shrimp flour) as an alternative carbon source for fungal growth was used, extracting the biopolymer chitosan. The production of chitosan occurred in all samples. The best sample (trial 1) showed a yield of 19%, containing variants: shrimp meal (0.5 g), glucose (0.5 g), pH (4), peptone (0.25 g) and yeast extract (0.15 g) and it was observed that under the same conditions with variation of pH of 4 was decreased to 8% yield of 3, most likely by increasing the pH and it was noted also that with increasing shrimp flour 0.5g and 0.5g I I REVISTA SAÚDE E CIÊNCIA On line, 2014; 3(3):11-17, set-dez, 2014.

These results demonstrate the positive effect of shrimp meal as an alternative carbon source for fungal growth.
