| The objective of this study was to evaluate the microbiological, physiological and qualitative changes in fresh cut yam (Dioscorea alata) stored at different temperatures. The experimental design was completely randomized in factorial scheme 4x4, with four storage temperatures (5, 10, 15 and 20ºC) and four evaluation periods (0, 3, 6 and 9 days after processing) with four replications. The microbiological analyzes were performed at 0, 3 and 9 days after processing. Fresh cut yam stored at 5ºC kept respiration rate, ethylene production at low levels similar to those found in yam not processed and stored at 20ºC. The weight loss, lightness and psicotrophic bacteria counting in fresh cut yam stored at 5ºC were kept within the trading patterns until the third... |

| The objective of this work was to access processing quality of potato clones (Solanum tuberosum) Asterix, SMINIA793101-3, and Missaukee cultivated during spring and autumn growing seasons and stored at 4, 8, 12, or 25ºC. Clones grown in spring had shorter dormancy than clones grown in autumn. Potato tubers grown in spring and autumn and stored at 4ºC, as well as tubers grown in autumn and stored at 8ºC had no sprouting for six months. Among clones grown in autumn, the longest dormancy period during storage at 12ºC was observed in the clone SMINIA793101-3, and at 25ºC was in the clone Asterix. In potato tubers grown in spring, the longest dormancy period during storage at 8ºC was observed in the clones SMINIA793101-3 and Missaukee, at 12ºC was in the clone... |

| Beet roots cv. Early Wonder were graded for firmness, color and size, and were peeled inside a cold room (10ºC). Roots were then shredded (2 mm thick), sanitized for 6 minutes (NaClO/200 mg L-1), rinsed and centrifuged. Fresh-cut beet roots were then treated for 5 minutes with citric acid in the following concentrations: 0 (control), 500; 1,000; 1,500 and 2,000 mg L-1. The material was centrifuged again, placed in trays, wrapped with PVC plastic film, and stored at 5ºC and 85-90% HR for 10 days. Every two days, treatments were analyzed for respiratory activity and betacyanin and betaxanthin contents. The application of citric acid caused the reduction of respiratory rate in the fresh-cut tissue. In the second day of storage, control showed the highest... |

| Исследованы особенности потребления кислорода и экскреции азота, а также их соотношение у мидий естественных поселений из районов чистой воды и хронического воздействия бытовых стоков. У моллюсков из биотопа загрязненной воды наблюдается пониженный уровень метаболизма. В условиях кратковременной аутогенной гипоксии критические уровни насыщения воды кислородом, лимитирующие обмен у моллюсков, проявляются при более низких величинах, по сравнению с мидиями из биотопов чистой воды. Ведущая роль в энергообеспечении метаболизма мидий из биотопа загрязненной воды принадлежит белково-азотистым субстратам, что свидетельствует об их меньшей устойчивости к воздействию неблагоприятных факторов. Скорость потребления кислорода и экскреции азота и их соотношение О/N... |

| Zooplankton community composition, biomass and metabolism can vary drastically over space and time in subtropical estuaries. Changing environmental conditions can affect communities differently, depending on the characteristics of the species involved. In the present study, we compared the rates of oxygen consumption of the dominant zooplankton taxa living in permanently open and in temporally open/closed estuaries. The metabolic response was tested at four temperatures experienced by the animals in their natural environment. Zooplankton from the temporally open/closed estuary showed low activation energies and low rate of metabolism at the highest temperature tested. Animals from the permanently open estuary had higher respiration rates at increased... |

| Knowing the metabolic balance of an ecosystem is of utmost importance in determining whether the system is a net source or net sink of carbon dioxide to the atmosphere. However, obtaining these estimates often demands significant amounts of time and manpower. Here we present a simplified way to obtain an estimation of ecosystem metabolism. We used artificial neural networks (ANNs) to develop a mathematical model of the gross primary production to community respiration ratio (GPP:CR) based on input variables derived from three widely contrasting European coastal ecosystems (Scheldt Estuary, Randers Fjord, and Bay of Palma). Although very large gradients of nutrient concentration, light penetration, and organic-matter concentration exist across the sites,... |

| Increased oligotrophication is expected for oligotrophic areas as a consequence of ocean warming, which reduces diffusive vertical nutrient supply due to strengthened stratification. Evidence of ocean oligotrophication has been, thus far, reported for the open ocean. Here we reported oligotrophication and associated changes in plankton community metabolism with warming in a pristine, oligotrophic Mediterranean coastal area (Cap Salines, Mallorca Island, Spain) during a 10 years time series. As a temperate area, there were seasonal patterns associated to changes in the broad temperature range (12.0.28.4.C), with a primary phytoplankton bloom in late winter and a secondary one in the fall. Community respiration (R) rates peaked during summers and showed... |

| On constate actuellement une profusion d'appareils d'aération en vente sur le marché. En même temps, il apparaît nécessaire pour les professionnels de la conchyliculture de s'équiper convenablement pour éviter l'apparition de mortalités en bassins de finition. Ceci impose donc la mise en place de suivis d'efficacité des différents systèmes utilisés, dans les conditions de travail de la profession en ce qui concerne le stockage des mollusques bivalves. Les premiers résultats permettent de classer quatre systèmes en terme d'efficacité, mais ne permettent pas encore de proposer des rythmes d'utilisation journaliers en toutes saisons. D'autres études en cours répondront à ce problème. Des résultats des mesures effectuées sur l'eau et sur les mollusques, il se... |

| Background The cattle gastrointestinal tract (GIT) is the main enterohemorrhagic Escherichia coli (EHEC) reservoir. In order to identify nutrients required for the survival or multiplication of EHEC in the bovine GIT, we compared the transcriptomes of the EHEC O157:H7 reference strain EDL933 cultured in vitro in bovine digestive contents (DCs) (rumen, small intestine and rectum) using RNA-sequencing. Results Gene expression profiles showed that EHEC EDL933 activated common but also specific metabolic pathways to survive in the different bovine DCs. Mucus-derived carbohydrates seem important in EHEC nutrition in posterior DCs (small intestine and rectum) but not in rumen content. Additional carbohydrates (xylose, ribose, mannitol, galactitol) as well as... |
