1. INFLUENCE OF HYDRAULIC RETENTION TIME ON HYDROGEN PRODUCTION BY TREATING CHEESE WHEY WASTEWATER IN ANAEROBIC FLUIDIZED BED BIOREACTOR - AN APPROACH FOR DEVELOPING COUNTRIES
Abstract This study assessed the effect of hydraulic retention time (HRT) on biohydrogen production by dark fermentation using an anaerobic fluidized bed reactor fed with cheese whey synthetic wastewater. The reactor of 1.2 L was operated with an approximate carbohydrate concentration of 2800 mg L-1, and HRTs of 6, 4, 2, 1 and 0.5 h. Acetic and butyric acids

2. Organic brown sugar and jaboticaba pulp influence on water kefir fermentation
RESUMO O kefir de água é considerado um alimento funcional com características probióticas. Pode ser melhorado com adição de açúcar mascavo orgânico e frutas nativas do Brasil, como a jabuticaba. Objetivou-se avaliar os efeitos do tipo de açúcar mascavo: orgânico e convencional e da presença ou ausência de polpa de jabuticaba na fermentação d

3. Enzymatically and/or thermally treated Macroalgae biomass as feedstock for fermentative H2 production
ABSTRACT Due to its high carbohydrate content, algae biomass can be employed as feedstock to produce hydrogen (H2) by fermentation. However, to make the carbohydrates entrapped within the cell wall more bioavailable, algae biomass must be treated before fermentation. We submitted Kappaphyccus alvarezzi macroalgae biomass to autoclave (at 120 °C and 1 atm fo

4. Characterization of ruminal acidosis and initial phase of laminitis inducted by oligofructose in crossbred calves
RESUMO: Uma das formas de se estudar a laminite bovina é sua indução experimental por meio do fornecimento de grande quantidade de carboidrato de alta fermentação. O protocolo mais eficaz até o momento foi o uso de oligofrutose. Objetivou-se avaliar aspectos clínicos e histológicos dos dígitos de bovinos na indução experimental de acidose ruminal

5. Intake and digestion of non-traditional feedstuffs by farmed collared peccary (Mammalia, Tayassuidae)
ABSTRACT To assess the ability of the collared peccary ( Pecari tajacu ) to digest dietary fiber, four adult male collared peccaries were randomly assigned to a 4 × 4 Latin square design to determine the effects of feeding non-traditional feed ingredients, taken from palm trees with different levels of dietary fiber, on intake and coefficient of total tract

6. Additives on in vitro ruminal fermentation characteristics of rice straw
ABSTRACT The objective of this study was to evaluate the effects of mineral and protein-energy (MPES), exogenous fibrolytic enzyme supplements (ES), combination of MPES + ES, and straw without supplement (WS) on digestibility, fermentation kinetic parameters, cumulative gas production, methane, CO2 production, and volatile fatty acid concentration of rice st

7. Bacaba beverage produced by Umutina Brazilian Amerindians: Microbiological and chemical characterization
Bacaba chicha is a beverage prepared by the indigenous Umutina people from the bacaba fruit (Oenocarpus bacaba), a purple berry that is rich in fat and carbohydrates, as well as a source of phenolic compounds. In this study, samples of bacaba chicha beverage were collected, and the microbial community was assessed using culture-dependent and -independent tec

8. BIOHYDROGEN FROM CHEESE WHEY TREATMENT IN AN AnSBBR: ACHIEVING PROCESS STABILITY
AbstractAn AnSBBR (anaerobic sequencing batch reactor containing biomass immobilized on an inert support) with liquid phase recirculation, containing a 3.5 L working volume, treated 1.5 L of cheese whey wastewater in 3 and 4 h cycles at 30 ºC to produce biohydrogen. From startup the bioreactor presented process instability. To overcome this problem the foll

9. Modulation of antimicrobial metabolites production by the fungus Aspergillus parasiticus
Biosynthesis of active secondary metabolites by fungi occurs as a specific response to the different growing environments. Changes in this environment alter the chemical and biological profiles leading to metabolites diversification and consequently to novel pharmacological applications. In this work, it was studied the influence of three parameters (ferment

10. Molecular characterization of lactobacilli isolated from fermented idli batter
Lactic acid bacteria are non pathogenic organism widely distributed in nature typically involved in a large number of spontaneous food fermentation. The purpose of this study was to characterize the bacteriocinogenic lactobacilli from fermented idli batter which can find application in biopreservation and biomedicine. Eight most promising lactobacilli were c

11. Rumen fermentation and rumen microbes in Nellore steers receiving diets with different lipid contents
The objective of the present study was to evaluate the effects of dietary lipid content (20, 40 and 60 g/kg dry matter) on intake, total and ruminal apparent digestibility of dry matter (DM), nutrient digestibility, rumen fermentation parameters, microbial synthesis efficiency and rumen microbial content of beef cattle. Nine cannulated steers at 6 months of

12. Avaliação do metabolismo primário da região cambial e casca de Eucalyptus grandis / Evaluation of the primary metabolism of Eucalyptus grandis cambial region and bark
Eucalyptus genus is the most widely planted hardwood crop in the world because of its superior growth, broad adaptability and multipurpose wood properties. In today\ s \"new carbon economy\", eucalypts are receiving attention as fast-growing, short-rotation, renewable biomass crop for energy production. In spite of its economical importance, little informati
