Evaluation of bacterial community and of actinomycetes composition from the Allium ursinum L. species rhizosphere

Soil s microbiota is an effective recycling instrument of organic matter, of nutritional resources providance for living organisms, an instrument of atmospheric nitrogen fixation in forests biomes. This one changes under the action of some abiotic and biotic factors. In this research, we have studied the impact of the plant of Allium ursinum L, the soil moisture and the way to prepare the soil in the laboratory condition, upon bacterial community and the composition of actinomycetes from the Streptomyces genus, from the forest soil. The soil studied belongs to a deciduous forest, located in the western part of the country. The soil s samples have been taken from the top layer of the soil (0-20 cm), from the Allium ursinum L. plants rhizosphere, plants which have been in their blossoming period. The microbian groups of interest have been isolated in specific environments resulted from soil s samples prepared beforehand by plants residue removal (SC) and sifting, as well as from original soil s samples which had no prior preparation (SN). The results show that the bacteria in the soil sample SC compared to the bacteria in the soil sample SN has dominated numerically. The bacterian species which predominated in both types of soil was Bacillus cereus var. mucoydes. The actinomycetes have been equal numerically in both soil’ samples mentioned below, but their diversity has been reduced. The highest number of species belonging to the genus of Streptomyces was isolated from soil sample SC. The species of actinomycetes, common for both soil samples were: S. albosporeus and S. albus. In the soil sample SC, S. albosporeus species dominanted, and in the soil sample SN, S.chromogenes was the most representative

Technical - economic evaluations experimental casuistry studied at core walnut oil

In this paper was performed study regarding guide technical and economic evaluations for core walnut oil obtained by extraction with petroleum ether, in a industrial unit considering 240 working days/year. The economic efficiency relies on analytic and synthetic indicators that give a general view about the production process. These indicators are used in order to calculate the profit of the factory enterprise. Monitoring of plant resources are essential for the development of modern agricultural production. Biodiversity of plant resources in agriculture is a biological basis for assurance the quality of world food products, for creating new cultivars, through conventional crossing process or application of biotechnology. The values obtained were as follows: total costs (736215 Euros/year), total revenues (817800 Euros/year), profit (81585 Euros/year), profit rate (11.08%), product cost (73400.63 Euros) and production costs (1301 Euros/kg). The results of technical-economic calculations estimated have positive values, suggesting that processing technology is profitable, the costs being lower than revenues, and therefore can be recommended as a potential technology solution for recovery of core walnut

The effect of biogel content on the some viscoelastic properties of a snail pate

Four sorts of snail pâté with different contents (0, 1, 2, 3%) of a vegetal protein (biogel) were prepared. The influence of the content of biogel on the viscoelastic characteristics of snail pâté were studied in this paper. These characteristics of snail pâté were derived from stress relaxation tests. The relaxation times and the elastic moduli, as viscoelastic characteristics, were calculated from the relaxation curves by non-linear regression. The best correspondence between experimental data and calculated curves was obtained for a mechanical model with three Maxwell elements in parallel with a lone ideal spring element. Every measurement was made in triplicate. From above viscoelastic parameters, the viscosities were calculated. Correlation between experimental relaxation curves and calculated curves were emphasized by absolute average deviation (AAD), the minimum AAD value being 0.15% and the maximum one 0.82%. The stiffest snail pâté contains 2% biogel, and the snail pâté with 3% biogel is more viscous

Physical-chemical characteristics of Triticum Aestivum wheat from three Romanian regions

The purpose of this paper was to determine the total protein content, gluten content, moisture, Zeleny sedimentation index, hectolitre mass and deformation index of T. aestivum wheat. The total protein content, gluten content, Zeleny sedimentation index and hectolitre mass was analyzed by the NIR, Infralum FT 10 cereal analyzer instruments. Humidity was determined by oven drying method and deformation index by thermostating. The samples were collected from three Romanian areas: West, South and Central. The highest total protein content was registered in wheat from South (13.5%), followed by wheat from West (13.2%), respectively from Centre (10.6%). The gluten content, in direct correlation with total protein content, was in the range 24% (wheat from Centre) - 30% (wheat from South). The deformation index of West and South samples was 5 mm, respectively 2mm of sample from Central. Wheat South Zeleny sedimentation index was 44 mL followed by West area wheat (49 mL) and wheat from Central (51 mL). The wheat samples hectolitre mass was very close, between 80.5-81.0 kg/hL. The humidity of the samples varied from 11.9% to 12.7%. The results recommend the wheat from South Romania area as being of high quality, followed by wheat from West Romania area. The wheat from Centre Romania area is of medium quality
