Produção De Amilases Pelo Fungo Macrophomina Phaseolina

Abstract: Amilases constituem um grupo de enzimas que possuem ação sobre o amido liberando diversos produtos, incluindo dextrinas e progressivamente pequenos polímeros compostos de unidades de glicose (GUPTA, et al., 2003). Apresentam importantes aplicações biotecnológicas principalmente nas indústrias farmacêutica, têxtil, detergente e alimentícia. Enzimas amilolíticas são produzidas por bactérias, leveduras e fungos. As enzimas amilolíticas mais utilizadas são aquelas produzidas por fungos filamentosos e principalment… Show more

“…Endoamylase activity was based on previously described methods [27,28], with slight modifications. The enzyme extract (10 lL) was incubated for 3 min with 90 lL of 0.5% (m/v) soluble starch (Vetec, Rio de Janeiro, Brazil) solution, followed by addition of 90 lL of an iodine solution belonging to an assay kit to quantify the residual starch (Laborlab, São Paulo, Brazil).…”

“…This is due not only to the particular characteristics of each strain and raw material, but also to the diversity of methodologies used for the quantification of the activities. Several studies report the activities of amylolytic enzymes measured at temperatures near to the gelatinization of starch, such as 60°C [20,21] and 65°C [22], whereas other works report the use of lower temperatures (50-55°C) [23][24][25]. Moreover, there are still some works that measure activity of amylases at no more than 40°C, claiming that the aim is to evaluate the potential of enzymes for cold starch hydrolysis [26,27].…”
