“…In this paper we showed an application of GAMLSS to model the bacterial cellulose yield using as covariates pH and cultivation time. The results showed in Figures 5 and 6 point out that the maximum bacterial cellulose yield is obtain for low values of pH and cultivation time close to 14 days, this results agree with the experiment of Castro et al (2012) that concluded that the optimal bacterial cellulose yield for this type of experiment is found near pH 3.5. The two explanatory variables used in the model were significant in explaining the mean and variance of bacterial cellulose yield; the equations 9 and 10 could be used by researchers to model (or predict) the system behavior under those conditions and to describe the variability of the bacterial cellulose yield.…”

In this paper, we present an application of GAMLSS (Generalized Additive Models for Location, Shape and Scale) to study bacterial cellulose production from agro-industrial waste. An experiment was conducted to research the effects of pH and cultivation time on bacterial cellulose yield obtained from discarded bananas. Several models were fitted to the collected data to determine an estimated expression for the mean and variance of bacterial cellulose yield. We found that the mean and variance of cellulose yield decrease as pH increases, while the opposite occurs as cultivation time increases.Palabras clave: GAMLSS models, Gamma distribution, linear regression, parameter estimation. ResumenEn este artículo se presenta una aplicación de los modelos GAMLSS (Generalized Additive Models for Location, Shape and Scale) para estudiar la producción de celulosa bacteriana a partir de residuos agroindustriales. El experimento fue realizado para investigar los efectos del pH y el tiempo de cultivo sobre el rendimiento de celulosa bacteriana obtenida a partir de residuos de banano. Varios modelos fueron ajustados a los datos recolectados para determinar expresiones estimadas 1 Hernández, F., Torres, M., Arteaga, L., Castro, C. (2015) 246Freddy Hernández, Mabel Torres, Lina Arteaga & Cristina Castro para la media y la varianza del rendimiento de celulosa bacteriana. Del mejor modelo obtenido se encontró que la media y la varianza del rendimiento de celulosa bacteriana disminuye a medida que el pH se incrementa, mientras al aumentar el tiempo de cultivo tanto la media como la varianza aumentan.

“…Mohammadkazemi et al (2015) reported a study of the effects of carbon sources and nitrogen concentration in the culture medium on BC production. Castro et al (2012) also showed the effect of the carbon source on BC production: the BC yield from glucose was the highest (3 g/L) while the medium containing sucrose yielded 2 g/L, and the media with fructose and mannitol -no more than 0.4 g/L. These data are consistent with the results reported in another study, which showed that such carbon sources as maltose, cellobiose, xylose, and galactose were less suitable for BC production by Acetobacter xylinum than glucose (Surma-Ślusarska et al,…”

“…The nitrogen content relates to the amino acids from the residual bacteria after purification. The BC crystallinity index is ∼0.65, with a I /I ratio of ∼0.74, indicating the enrichment of the I polymorph [38]. Dulbecco's Modified Eagle Medium, foetal calf serum, and fibroblasts in primary culture were employed for cell culturing.…”

We investigated wound dressing composites comprising fibrils of bacterial cellulose (BC) grown by fermentation in the presence of polyvinyl alcohol (PVA) followed by physical crosslinking. The reference biointerface, neat BC, favoured adhesion of fibroblasts owing to size exclusion effects. Furthermore, it resisted migration across the biomaterial. Such effects were minimized in the case of PVA/BC membranes. Therefore, the latter are suggested in cases where cell adhesion is to be avoided, for instance, in the design of interactive wound dressings with facile exudate control. The bioactivity and other properties of the membranes were related to their morphology and structure and considered those of collagen fibres. Bioactive materials were produced by simple 3D templating of BC during growth and proposed for burn and skin ulcer treatment.
