Caracterização molecular de acessos de mandioca açucarados e não açucarados

Abstract: RESUMOAcessos de mandioca que armazenam açúcares livres em suas raízes de reserva e não somente amido, como os acessos de mandioca cultivados comercialmente, vêm recebendo destaque atualmente. Esses acessos são popularmente conhecidos como mandiocas açucaradas ou mandiocabas, e evidenciam potencial de uso na produção de álcool combustível. Entretanto, esse germoplasma ainda não foi suficientemente estudado quanto àsua variabilidade genotípica, o que é fundamental para sua conservação e utilização no melhoramen… Show more

“…Unlike most varieties, sugary cassava is not predominantly starch (Carvalho et al, 2004). Vieira et al (2011) found genetic differences between sugary and non-sugary cassava varieties in terms of carbohydrate reserves. According to Carvalho et al (2004), the difference in the distribution patterns of starch and free sugars can be attributed to the hydrolysis of starch either by the phosphorylytic degradation mechanism or by the cleavage of starch by a series of starch hydrolytic enzymes, such as that occurring during seed germination in cereals, or by both.…”

“…In biotechnological processes used in PHA production, such as submerged fermentation, sugary cassava stands out as an attractive carbon source because it can be used to prepare Production of medium-chain-length polyhydroxyalkanoate by Pseudomonas oleovorans grown in sugary cassava extract supplemented with andiroba oil an extract with a high concentration of free monosaccharides (glucose and fructose) (Vieira et al, 2011). Thus, the starch hydrolysis step may be omitted in the production of fermentable sugars that are able to sustain bacterial growth and biopolymer production, reducing production costs.…”

“…Assim, a mandioca que sempre foi cultivada em função de suas raízes tuberosas ricas em amido e/ou de sua parte aérea rica em proteínas, apresenta agora novas possibilidades de utilização na indústria (VIEIRA et al, 2011). Esses acessos diferenciados podem vir a ser empregados na produção de glicose sem hidrólise do amido, na produção de amido com variabilidade na proporção amilose/amilopectina, na produção de amido do tipo glicogênio, na produção deálcool (combustível e para indústria de cosméticos), na siderurgia, entre outras utilidades (CAR-VALHO et al, 2004).…”
