1. Effects of CO2 pretreatment on the volatile compounds of dried Chinese jujube (Zizyphus jujuba Miller)
Abstract The aim of this study was to investigate whether anaerobic metabolites could induce volatile compounds and improve aroma of dried jujube (Ziziphus jujuba Miller). Jujube fruits were incubated in a polyvinyl chloride bag containing 5% CO2 and 95% N2 for up to 168 h at 25 °C and 3 samples were randomly removed every 6 h and oven dried to a moisture c

2. Waterlogging-induced changes in fermentative metabolism in roots and nodules of soybean genotypes
Waterlogging blocks the oxygen supply to the root system which inhibits respiration, and greatly reduces the energy status of cells that affect important metabolic processes. This study evaluated fermentative metabolism and carbohydrate contents in the root system of two soybean (Glycine max L. Merril) genotypes under hypoxic and post-hypoxic conditions. Nod

3. ESTRESSE INICIAL E CONDICIONAMENTO AO BAIXO OXIGÊNIO NO ARMAZENAMENTO EM ATMOSFERA CONTROLADA DE MAÇÃS ROYAL GALA / INITIAL STRESS AND CONDITIONING TO LOW OXYGEN IN CONTROLLED ATMOSPHERE STORAGE OF ROYAL GALA APPLES
O objetivo do presente trabalho foi avaliar métodos alternativos à atmosfera controlada convencional (AC) e dinâmica (ACD), na manutenção da qualidade de maçãs Royal Gala, em especial a ocorrência de distúrbios fisiológicos. Para tanto, avaliou-se o efeito do estresse inicial com baixo O2 na manutenção da qualidade de maçãs armazenadas em condi

4. A novel acidophilic, thermophilic iron and sulfur-oxidizing archaeon isolated from a hot spring of tengchong, yunnan, China
A novel thermoacidophilic iron and sulfur-oxidizing archaeon, strain YN25, was isolated from an in situ enriched acid hot spring sample collected in Yunnan, China. Cells were irregular cocci, about 0.9-1.02 µm×1.0-1.31 µm in the medium containing elemental sulfur and 1.5-2.22 µm×1.8-2.54 µm in ferrous sulfate medium. The ranges of growth and pH were 50

5. APLICAÇÃO DE PRODUTOS DA FERMENTAÇÃO E ULTRABAIXO OXIGÊNIO PARA A CONSERVAÇÃO DE MAÇÃS ROYAL GALA
The aim of this work was to evaluate the effect of post harvest ethanol or acetaldehyde application and to compare them with consolidated storage techniques on the quality maintenance of Royal Gala‟ apples. Also, we aimed to evaluate the effect of controlled atmosphere condition with ultra low oxygen partial pressures on the post storage quality mainte

6. The contribution of genes required for anaerobic respiration to the virulence of Salmonella enterica serovar Gallinarum for chickens
Salmonella enterica serovar Gallinarum (SG) is an intracellular pathogen of chickens. To survive, to invade and to multiply in the intestinal tract and intracellularly it depends on its ability to produce energy in anaerobic conditions. The fumarate reductase (frdABCD), dimethyl sulfoxide (DMSO)-trimethylamine N-oxide (TMAO) reductase (dmsABC), and nitrate r

7. Anatomic and physiological characterization and conservation of minimally processed carrots / Caracterização anatômico-fisiológica e conservação de cenoura minimamente processada
The objective of this study was to characterize the dehydration, white blush and histological location of suberin, lignin and phenolic compounds and assess their contribution to superficial white blush in baby carrots. The effects were assessed of the controlled atmospheres consisting of 2 % O2 + 15 % CO2, 5 % O2 + 5 % CO2 and 10 % O2 + 10 % CO2, all with N2

8. Dry material losses and qualitative evaluation of corn grain stored in hermetic units / Determinação da perda de matéria seca e avaliação qualitativa de grãos de milho armazenados em bolsas herméticas
A significant increase in the grain sector has been observed over the last few years, leading to the expansion of the balance of trade. However, in various Brazilian States, storage systems are composed of old structures, precarious for storage which end up compromising the quality of the product during storage. In order for the sector to increase exports an

9. Modelagem da decomposição aeróbia de lodo de esgoto em solos com diferentes texturas
The overall assessment of soil clay content on several phases of sludge decomposition, monitored as CO2 evolution, was the main objective of this work. Different soil textures obtained from the same sample matrix allowed correlations of the soil clay content, microbial biomass and organic carbon using soil respiration monitored as cumulative CO2 generation.

10. Effect of phosphate on the multiplication of Saccharomyces cerevisiae in continuous cultivation / Efeito de fosfato sôbre a multiplicação de Saccharomyces cerevisiae em cultivo contínuo
The influence of phosphate in a continuous culture was studied using mini-fermentor on the Saccharomyces cerevisiae multiplication. Dry matter, substrate concentration, specific substrate comsumption, specific carbon dioxide release, specific oxygen uptake rates and respiration quotient , as well as phosphorous content of the cells were measured in dependenc

11. Energy Transduction by Anaerobic Ferric Iron Respiration in Thiobacillus ferrooxidans
Formate-grown cells of the obligately chemolithoautotrophic acidophile Thiobacillus ferrooxidans were capable of formate- and elemental sulfur-dependent reduction of ferric iron under anaerobic conditions. Under aerobic conditions, both oxygen and ferric iron could be simultaneously used as electron acceptors. To investigate whether anaerobic ferric iron res

12. Anaerobic Respiration Using Fe3+, S0, and H2 in the Chemolithoautotrophic Bacterium Acidithiobacillus ferrooxidans
The chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans has been known as an aerobe that respires on iron and sulfur. Here we show that the bacterium could chemolithoautotrophically grow not only on H2/O2 under aerobic conditions but also on H2/Fe3+, H2/S0, or S0/Fe3+ under anaerobic conditions. Anaerobic respiration using Fe3+ or S0 as an electro
