The environmental conditions and the pretreatment of coffee pulp for solid-state Penicillium commune fermentation at semi-pilot scale were studied. The semi-pilot reactor used had a capacity of nearly 26 Kg of wet pulp, and an internal mixing system consisted of two helicoidal ribbons. The environmental conditions studied were: initial moisture,...
The main purpose of this work was to determine the significant WnditiQnS of cultivation that enhanced the production of diacetyl in a mixed culture of fediococcus pentosaceus and Lactobacillus acidophilus Hansen 1748, when grown in a cornbased semisolid medium. Taking into account that diacetyl is the main component in the...
El crecimiento de la industria camaronera ha generado gran cantidad de desechos, principalmente la cabeza y caparazón, que no son aprovechados y representan un grave problema de contaminación. El pigmento carotenoide más abundante en los desechos de camarón es la astaxantina (3,3'dihidroxi-ß-caroteno 4,4-diona), utilizada en la dieta de salmónidos para...
Solid state culture is considered as an alternative to traditional submerged or liquid culture. However, the lack of technical scale up knowledge has limited its application at pilot and industrial scale. The aim of this work was evaluate the effect of mixing over the CO2 production in cultures of septate...
