chemical proprieties of encapsulated host-molecules.The culture media required for the production of this enzyme usually includes carbon and nitrogen sources obtained by expensive processes. Therefore, approaches in pursuit of low cost substrates, especially from agro-industrial origins, have been developed with an objective to decrease production costs of CGTase at commercial scales.14–18In this scenario, the use of cassava flour (Manihot esculenta Crantz) as a carbon sourcein fermentation processes for CGTase production, has gainedan intense interest. Cassava flour, an agro-industrial product containing 60–80% starch, can be obtained by a simple low cost process.19In Brazil, it is a widespread agronomic product specifically of the North and Northeast regions.20,21Its qualityis directly related to the physical and chemical characteristics of the cassava roots, plant genotype and age, favorable envi-ronmental conditions, harvest period, soil characteristics,genetic variability, and the processing method
