RESUMO
The present study was conducted to evaluate the cellulose production by Gluconacetobacter kakiaceti GM5 by means of two aerobic treatments: the static discontinuous fermentation process (treatment 1) and the discontinuous fermentation process in a rotary shaker (treatment 2). All these experiments were carried out using vinasse as experimental culture media (VM) and were compared with standard media containing glucose at 2% (standard medium (SM)). A sample of each treatment was extracted every 24 h over a period of 168 h. The maximum rates of cellulose produced in treatment 1 using SM added up to 3.63 ± 0.18 g l(-1), and to 4.15 ± 0.16 g l(-1) when VM was used. The amount of cellulose produced in treatment 2 using SM was 2.95 ± 0.09 g l(-1) (which suggests an increase of 37%), and added up to 1.84 ± 0.07 g l(-1) when using VM. A better global yield of both treatments in terms of sugar consumption after 168 h was obtained when using VM: 32% in treatment 1, whereas in treatment 2 it was 9%. A 20% decrease on vinasse COD (Chemical Oxygen Demand) values was found to be yet another important advantage of working with this strain.

El propósito de esta investigación consistió en estudiar la calidad de vida y la conducta de enfermedad en personas con diabetes y observar si existe relación entre ellas. Para ello se aplicó el cuestionario SF-36 y el IBQ a 74 pacientes con edades comprendidas entre los 45 y 65 años diagnosticados con diabetes mellitus tipo II, no insulinodependientes. Se evidenció deterioro importante en la calidad de vida de estos pacientes, principalmente en aquellos componentes relacionados con la salud física. La conducta de enfermedad puntuó en el rango medio en todas sus dimensiones, aproximándose a un nivel alto la hipocondriasis general. Se encontraron correlaciones inversas entre la función física, con percepción psicológica versus somática de la enfermedad. La salud mental correlacionó también de forma negativa con distorsión afectiva, negación de los problemas e irritabilidad. La relación existente entre las dimensiones evaluadas permite una aproximación al planteamiento de patrones de respuesta a la enfermedad, que redundan en la calidad de vida del paciente con diabetes.
The intention of this study was to study the quality of life and the conduct of disease in people with diabetes and to observe if relation among them exists. For it is was applied to questionnaire SF-36 and the IBQ to 74 patients with ages between the 45 and 65 years diagnosed with diabetes mellitus type II. Important deterioration in the quality of life of these patients was demonstrated, mainly in those components related to the physical health. The disease conduct scored in the average rank in all its dimensions, coming near at a high level the general hipocondriasis. Were inverse correlations between the physical function, with psychological perception versus somatic of the disease. The mental health also correlated of negative form with affective distortion, negation of the problems and irritability. The existing relation between the evaluated dimensions allows an approach to the...
