Soil microbial populations play crucial role in soil properties and influence below-ground ecosystem processes. Microbial composition and functioning changes the soil quality through decomposition of organic matter, recycling of nutrients, and biological control of parasites of plants. Moreover, the discovery that soil microbes may translate into benefits(More)
It was recently shown that induction of long-term potentiation (LTP) in the visual cortex of adult rats does not require suppression of inhibition or N-methyl-D-aspartate (NMDA) receptor activation. In the present study we examined the role of dihydropyridine-sensitive Ca2+ channels in the induction of this form of LTP. In visual cortical slices from 60 to(More)
The occurrence of Clostridium perfringens was estimated in 750 samples originated from a variety of soils bearing various bulb crops: Brawnica oderacea (vegetable), Olea europaea, Daucus carota (carote), Solanum tuberosum (potato), Phaseolus vulgaris (green haricot), Beta vulgaris var. rapaceum (beetroot), Cucurbita pepo (squash), Allium cepa (onion),(More)
Soil microbes play an important role in nutrient cycling and in the decomposition of organic matter and influence aboveground ecosystems by contributing to plant health and soil fertility (Yao et al. 2000; O’Donnell et al. 2001). Cultivated soils are complex ecosystems because of the inputs of pesticides and fertilizers and because of their ability to(More)
The aim of the present study was to evaluate the microbial ecosystem of cultivated soils along the Evros river in NE Greece. Evros river together with its derivative rivers constitute the capital source of life and sustainable development of the area. Along this riverside watery ecosystem systematic agro-cultures were developed such as wheat, corn and(More)
Ozone was used to control spoilage microorganisms during the manufacturing of dairy products. Ozone stream was applied onto the surface of freshly filled yoghurt cups just before storage for curd development in order to prevent cross contamination from spoilage airborne microorganisms. Accordingly, brine solution was bubbled with ozone for various periods(More)
A new tool that will exploit the benefits of ICT technology and promote biomass entrepreneurship is presented: BI.O.MA.S. This new approach is based on a web-based tool for the real-time biomass supply chain management, an online marketplace combined with an auction platform for biomass products/services and the release of an app for smartphones and mobile(More)
