Chemical Characterization of Six Microalgae with Potential Utility for Food Application
The results suggest that the freshwater species C. vulgaris and S. platensis are attractive nutritional supplements because of their low fiber and high protein/carbohydrate contents, while the marine species P. tricornutum and N. oculata can enrich foods with LC-PUFA-ω3, because of the favorable ω3/ω6 ratio.

Polyunsaturated ω-3 and ω-6 fatty acids, total carotenoids and antioxidant activity of three marine microalgae extracts obtained by supercritical CO 2 and subcritical n -butane
Abstract Microalgae are one of the most promising sources for new functional food products, due to their ability to synthesize polyunsaturated fatty acids, pigments and natural antioxidants (e.g.Expand
Production of bioactive compounds with antitumor activity against sarcoma 180 by Pleurotus sajor-caju.
Information is provided about culture medium and conditions that enhanced the production of extracellular polysaccharides by P. sajor-caju that can contribute to the search for new bioactive products bringing novel aspects to the medical and pharmaceutical areas. Expand
Study of the bio-production of carotenoids by Sporidiobolus salmonicolor (CBS 2636) using pre-treated agro-industrial substrates
BACKGROUND: The increasing industrial demand for carotenoids has aroused interest in their bio-production, and the need to reduce production costs has encouraged the use of low cost industrialExpand
Production of bio-inseticide Bacillus thuringiensis var. israelensis in semicontinuous processes combined with batch processes for sporulation
The aim of this work was to study the production of the bioinsecticide using the aerobic cultivation. Two-stage cultivation process was used: aerobic vegetative growth and end-phase of sporulationExpand
Colonization of solid particles by Rhizopus oligosporus and Aspergillus oryzae in solid-state fermentation involves two types of penetrative hyphae: A model-based study on how these hyphae grow
A discrete model is developed to describe the biomass distribution of penetrative hyphae as a function of depth inside solid particles and applies this model to Rhizopus oligosporus and Aspergillus oryzae, growing in different media. Expand
More random-walk than autotropism: A model-based study on how aerial hyphae of Rhizopus oligosporus grow in solid-state fermentation
Abstract During solid-state fermentation, aerial hyphae occupy the interparticle spaces, binding adjacent particles and decreasing the efficiency of mass and heat transfer within the bioreactor bed.Expand
Substrate Specificity and Enzyme Recycling Using Chitosan Immobilized Laccase
To assess the influence of different substrate functional groups on the enzyme’s catalytic efficiency, substrate specificity was investigated using chitosan-immobilized laccase and eighteen different phenol derivatives and it was observed that 4-nitrophenol was not oxidized and 2,5-xylenol showed reaction yields up 90% at 40 °C.

Effect of soluble solids concentration on Neosartorya fischeri inactivation using UV-C light.
It can be concluded that UV-C light is a promising treatment with a drastic impact on the loads of N. fischeri, especially when low soluble solids concentration is used and a model was obtained to describe Brix effect. Expand
Obtaining soybean peroxidase from soybean hulls and its application for detoxification of 2,4-dichlorophenol contaminated water
Abstract This work aimed to evaluate the performance of soybean peroxidase on 2,4-dichlorophenol bioconversion. Soybean peroxidase was obtained from transgenic cultivar and purified to homogeneityExpand
