Producción de exopolisacáridos tipo fructooligosacáridos por Gluconacetobacter diazotrophicus

Abstract: Como objetivo general para este trabajo se planteó intentar sentar las bases para el desarrollo de una tecnología de producción de FOS y levanos, y de la enzima responsable la síntesis de estos compuestos (LsdA), por G. diazotrophicus en escala de laboratorio utilizando diferentes estrategias de cultivos. Dentro de este planteo general se definieron diferentes objetivos específicos. 1. Debido al desconocimiento de la regulación metabólica de la síntesis de polisacáridos extracelulares por G. diazotrophicus, cu… Show more

“…This can be explained by the fact that the determination of total sugars was influenced by the production of exopolysaccharides by the bacteria, which caused interference in the tests performed. This condition was also identified by Molinari [23] during batch cultivations using culture media containing 10 and 100 g/L sucrose. The production of extracellular polysaccharides by G. diazotrophicus has been demonstrated in several works [35,59,62].…”

“…In this work, the quantification of the carbon source was performed according to DuBois et al [39]. Regarding this, the final sucrose concentration is not quantified in the case of most related papers published in the available literature addressing kinetic experimental studies on G. diazotrophicus [21,23]. In fact, the estimation of the biomass yield in those works was calculated from the cell concentration data obtained by optical density.…”
