Modelado de la biodegradación en biorreactores de lodos de hidrocarburos totales del petróleo intemperizados en suelos y sedimentos (Biodegradation modeling of sludge bioreactors of total petroleum hydrocarbons weathering in soil and sediments)

Abstract:Organic biomass is an attractive feedstock for second generation alcohol production. Wild-type strains of the genus Candida showed capabilities different to produce alcohol fermenting a carbohydrates mixture (synthetic medium), individually and in co-culture. Therefore, the main objective of this work was to evaluate the capability of Candida wild-type strains isolated from termite gut and rumen liquid, to ferment the most commonly carbohydrates presented in citrus residues, individually and in co-culture to alcohol production. C. Tropicalis (LR4) presented higher percentage of carbohydrate consumption (74.20% ± 4.60%), alcohol production (44.53 ± 0.01 gL -1 ) and maximal alcohol productivity (6.40 ± 0.01 gL -1 day) than C. Glabrata (T1). Co-culture schemas, CC1 (LR4: 60%; T1: 40%) and CC3 (first LR4 alone and 2 days later T1) presented the highest alcohol production (45.20 ± 1.30 gL -1 and 46.80 ± 2.60 gL -1 , respectively). Maximal alcohol productivity was obtained with CC2 (LR4: 80%; T1: 20%) and CC3 schemas, 7.70 ± 0.29 gL -1 day and 7.80 ± 0.44 gL -1 day, respectively. The results suggest the usefulness of these wild-type strains in co-culture as an alternative to alcohol production from carbohydrates mixtures at concentrations commonly found in citrus waste.

Las ficobiliproteínas, como las ficocianinas que se extraen de las cianobacterias, tales como la Spirulina Plantesis son los principales pigmentos accesorios de la fotosíntesis en las cianobacterias. Se encuentran en asociación con la superficie exterior de las láminas fotosintéticas y forman parte del aparato de captación de luz del fotosistema II de luz.
