Isolation, identification and characterization of a novel high level β-glucosid...

Made available in DSpace on 2022-04-29T07:12:07Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-10-01; The aim of this work was to prospect for microorganisms in the local environment, selecting those with higher production of cellulolytic and hemicellulolytic enzymes. A total of 36 microorganisms were isolated in a sugarcane-based medium. Colonies were replated in medium containing carboxymethylcellulos...

Physicochemical properties, mineral and fatty acids composition of Jackfruit se...

Jackfruit seeds are usually discarded as waste. Therefore, this work aimed at obtaining the Jackfruit seeds flour of two varieties (soft and firm) from Brazilian Midwest and to evaluate its physicochemical characteristics, mineral and fatty acids composition (FA). Seeds were dried at 45°C for 72h and ground (40-mesh). Both flours revealed high protein content, varying from 13.43% to 16.28%. It also revealed exc...

Growth and proximate composition of Pleurotus ostreatus cultivated on green boc...

The aim of this work was to evaluate the growth and the proximate composition of the mycelium-based bocaiuva pulp with the edible mushroom Pleurotus ostreatus on green bocaiuva flour added with different sources of nitrogen (urea, ammonium nitrate and sulfate ammonia). Growth was monitored by kinectics. At the end, the proximate composition of the best three treatments (dehydrated green bocaiuva pulp and water,...

Characterization of different microalgae cultivated in open ponds

 Microalga is one of the main sources of biomasses for the production of biofuels in the 21st century. Many labs and industries around the world are seeking for more productive strains and better cultivation models. The aim of this work was to evaluate the growth and kinetic parameters of six microalgae, and the moisture and lipid contents and fatty acids profiles of the biomasses harvested at the end of each c...

Production and catalytic properties of amylases from Lichtheimia ramosa and The...

Made available in DSpace on 2018-12-11T17:04:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01; The present study compared the production and the catalytic properties of amylolytic enzymes obtained from the fungi Lichtheimia ramosa (mesophilic) and Thermoascus aurantiacus (thermophilic). The highest amylase production in both fungi was observed in wheat bran supplemented with nutrient solution (pH...

Catalytic properties of cellulases and hemicellulases produced by Lichtheimia r...

Made available in DSpace on 2018-12-11T16:53:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-10-15; The use of microbial enzyme cocktails for the conversion of polysaccharides of plant origin into fermentable sugars is a global trend. The objectives of this study were to optimize the production of cellulases and hemicellulases by the fungus Lichtheimia ramosa, evaluate the catalytic properties of the ...

Screening of an adapted culture medium composed by different carbon sources for...

  The ability of microalgae to grow heterotrophically lies in the ability to oxidize organic compounds present in the external environment. The aim of this work was to evaluate the growth of Chlorella vulgaris under heterotrophic culture conditions using Basal Bold and NPK media supplemented with different sole carbon sources (glucose, fructose, sucrose, glycerol or acetate). The kinetic parameters obtained wer...

Growth of Burkholderia sacchari LFM 101 cultivated in glucose, sucrose and glyc...

Production of xylanase by a new strain of Thermoascus aurantiacus: obtainment o...

Xylanases are useful in several industrial segments, including pulp and paper bleaching, animal feed, and bread-making processes. However, the industrial use of these enzymes is closely related to its production cost and its catalytic properties. The process of solid state fermentation enables the use of agro-industrial residues as substrates for microbial cultivation and enzymes production, reducing costs. In ...
