1. Use of elephant grass (Pennisetum purpureum) as substrate for cellulase and xylanase production in solid-state cultivation by Penicillium echinulatum
Abstract The high cost of the enzymes used for the hydrolysis of lignocellulosic biomass is one of the bottlenecks in the production of second-generation ethanol and the use of local biomass, such elephant grass, can help to reduce this cost. In this investigation elephant grass biomass was evaluated as a carbon and inducer source of production of cellulases

2. BIOPROCESS DEVELOPMENTS FOR CELLULASE PRODUCTION BY Aspergillus oryzae CULTIVATED UNDER SOLID-STATE FERMENTATION
Abstract Bioprocess development studies concerning the production of cellulases are of crucial importance due to the significant impact of these enzymes on the economics of biomass conversion into fuels and chemicals. This work evaluates the effects of solid-state fermentation (SSF) operational conditions on cellulase production by a novel strain of Aspergil

3. Produção de celulases, purificação e caracterização bioquímico-cinética da β-galactosidase produzida por fungo isolado da região amazônica / Production of cellulases, purification and characterization of kinetic biochemical ß-galactosidase produced by fungus isolated from the Amazon.
The selection of cellulase-producing fungi is one of the possible estrategies for obtaining necessary enzymes to hydrolyze the lignocellulosic material of plant biomass and thereby contribute to the viability of cellulosic ethanol production. The aim of this study was achive a screening of isolated fungi from the Amazon region to assess the production of enz

4. Selection of thermophilic and thermotolerant fungi for the production of cellulases and xylanases under solid-state fermentation
Twenty-seven thermophilic and thermotolerant fungal strains were isolated from soil, decaying organic matter and sugarcane piles based on their ability to grow at 45ºC on medium containing corn straw and cardboard as carbon sources. These fungi were identified in the genera Aspergillus, Thermomyces, Myceliophthora, Thermomucor and Candida. The majority of t

5. Produção de acido hialuronico por cultivo em estado sólido de Streptococcus zooepidemicus em em bagaço de caju / Hyaluronic acid production by by state Streptococcus zooepidemicu in cashew apple bagasse
ln this work, hyaluronic acid (HA) production was studied the in solid state cultivation (SSF) of Streptococcus zooepidemicus, focusing on metabolic changes induced by varying the initial sugar concentration (ICS), initial concentration of ascorbate (ICAsc), volumetric air flow rate, oxygen availability and particle size. The first approach shows the compari

6. Evaluation of bioavailability of heavy metals in urban waste in solid for extractors in Brazil
The organic fraction of urban solid waste (USW) is around 60% of the total. The composting is a simple and efficient process to recycle this fraction of the USW, transforming it in organic fertilizer. The compounds of waste can contain a value assigned to aggregate economic potential of reuse of micronutrients (Cu, Ni and Zn) contained therein, in the produc

7. Produção de goma xantana utilizando casca de soja como substrato em cultivo submerso e cultivo semi-sólido / Xanthan gum production using soybean hull substrate by submerged and solid-state cultnations
A goma xantana continua sendo o polissacarídeo microbiano mais produzido no mundo. Características como aumento da viscosidade em soluções, agente de geleificação, estabilidade frente aos diversos tratamentos despertam um interesse especial para a indústria de alimentos, porém, a aplicação para fins não alimentícios vem crescendo significativamen

8. Solid State production of manganese peroxidases using arecanut husk as substrate
The lignocellulosic biomass from arecanut husk (Areca catechu Linnaeus) was evaluated as a new substrate for cultivation of Phanerochaete chrysosporium and Phanerochaete sp for solid state fermentation of manganese peroxidase (MnP). Arecanut had a moisture content of 79.84 % for ripe nut husk whereas green nut husk had 68.39 % moisture and a pH of 5.0, 3.0 a

9. Funcionalidade dos extratos fenólicos obtidos pelo cultivo semi-sólido de resíduos de abacaxi (Ananas comusus L.) e goiaba (Psidium guajava L.)
Solid substrate cultivation (SSC) has become an efficient alternative towards rational use of agro industrial wastes and production of value-added products, mainly in developing countries. This work presents the production and functional application results of phenolic extracts obtained by solid substrate cultivation of pineapple (Ananas comosus L.) and guav

11. Prospecção de genes de interesse biotecnológico : uma abordagem metagenômica
The total number of prokaryotic cells on Earth has been estimated at 4 to 6x1030 and only about 1% of microorganisms present in the environment can be cultivated by standard techniques of cultivation and plating. Therefore, it is a huge biological and genetic pool that can be exploited, for the identification and characterization of genes with biotechnologic
