1. WATER HOLDING CAPACITY AND HEAT TRANSFER ASPECTS OF A MIXTURE OF SUGAR CANE BAGASSE AND WHEAT BRAN IN A PARTIALLY FILLED ROTATING DRUM
Abstract Maximum water holding capacity of a mixture of sugarcane bagasse and wheat bran was determined in static conditions and in a drum rotated at 1 rpm. The variables filling degree, water flow rate, volume of added water and number of sprinklers were tested to control the moisture content of the solid and the number of rotations to achieve homogeneous m

2. Cycle, physicochemical characterization and climatic adaptation of a white hybrid grape on different rootstocks
ABSTRACT This study evaluated the cycle duration, physicochemical characteristics of fruits and climatic adaptation of the ‘SR 501-17’ hybrid grape grafted on four rootstocks for the production of white wine. We tested four rootstocks, ‘IAC 766 Campinas’, ‘IAC 572 Jales’, ‘IAC 571-6 Jundiaí’ and ‘IAC 313 Tropical’, planted in two climati

3. Crude Fermented Extract Containing Gibberellic Acid Produced by Fusarium moniliforme is an Alternative to Cost Reduction in Biofactories
ABSTRACT Nidularium procerum and Nidularium innocentii (Bromeliaceae) were cultivated in vitro on media supplemented with different sources and levels of GA3 (gibberellic acid). These sources were the commercial powder (analytical degree) and fermented extract obtained by Fusarium moniliforme via solid state fermentation. The in vitro elongation and rooting

4. 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

5. Fodder radish cake (Raphanus sativus L.) as an alternative biomass for the production of cellulases and xylanases in solid-state cultivation
Abstract Fodder radish (FR) is an oilseed crop with a high potential for biodiesel production due to its high productivity and the quality of its seed oil. FR oil extraction results in a residue that is rich in protein and fiber. In this study, FR cake (FRC) was evaluated as carbon and nitrogen source for the production of cellulases and xylanases using Peni

6. OXYGEN TRANSFER IN THE SOLID-STATE CULTIVATION OF D. monoceras ON POLYURETHANE FOAM AS AN INERT SUPPORT
Abstract In recent years, there has been a resurgence of interest concerning solid-state cultivation processes due to a number of advantages over submerged cultivation. However, studies on oxygen transfer and the performance of bioreactors are lacking. Processes that use inert supports loaded with chemically-defined liquid media have several potential applic

7. 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

8. INFLUENCE OF SOLID MOISTURE AND BED HEIGHT ON CULTIVATION OF Aspergillus niger FROM SUGARCANE BAGASSE WITH VINASSE
AbstractSolid-state cultivation (SSC) may be defined as growth of microorganisms on a solid support impregnated or not with a nutrient solution in near absence of free-water conditions. The use of sugarcane bagasse as a support for SSC usually demands that the particles are impregnated and moistened with nutrient solution. Vinasse is the main wastewater of e

9. Downstream processing of pectinase produced by Aspergillus niger in solid state cultivation and its application to fruit juices clarification
In this work, a protocol for the formulation of an enzyme concentrated product to be applied in fruit juice treatment is described. Downstream processing conditions for the recovery and concentration of pectinases produced by the new strain Aspergillus niger LB-02-SF in solid state cultivation were assessed. The solid-liquid ratio in the extraction step of p

10. Filamentous fungi and media for cellulase production in solid state cultures
Cellulase production was evaluated in two reference strains (T. reesei Rut-C30 and T. reesei QM9414), two strains isolated from a sugarcane cultivation area (Trichoderma sp. IPT778 and T. harzianum rifai IPT821) and one strain isolated in a program for biodiversity preservation in São Paulo state (Myceliophthora thermophila M77). Solid state cultures were p

11. Secretion of laccase and manganese peroxidase by Pleurotus strains cultivate in solid-state using Pinus spp. sawdust
Pleurotus species secrete phenol oxidase enzymes: laccase (Lcc) and manganese peroxidase (MnP). New genotypes of these species show potential to be used in processes aiming at the degradation of phenolic compounds, polycyclic aromatic hydrocarbons and dyes. Hence, a screening of some strains of Pleurotus towards Lcc and MnP production was performed in this w

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
