Klebsiella pneumoniae and Acinetobacter spp. strains are opportunistic pathogens frequently involved in the etiology of nosocomial infections in immunocompromised patients. A major factor amplifying the risk of these infections is prolonged period of hospitalised patients, especially in intensive care units. Statistically, the strains belonging to the Enterobacteriaceae family and those of the Acinetobacter spp. are ranked the first and respectively, the second among Gram negative bacilli, whose incidence has incr...

Grape juice consumption has increased significantly in recent years due to the beneficial health effects showed by products derived from grape. Grape juice is the unfermented drink obtained from simple must, sulfated or concentrated, from healthy, fresh and ripe grapes. When grape juice is processed with the aim of obtaining a shelf-stable product, its product shelf-life is determined by a best-before date, which is limited due to physical and (bio) chemical reactions. With the change of these properties, the micr...

Nowadays, green technologies and agri-environment measures play a vital role for sustainable development. Taking into consideration that more than a half of the Romanian land is farmed, agriculture is very important for the Romanian natural environment. The aim of this paper is to provide a detailed picture of the Romanian agri-environment measures and to outline the importance of agri-environmental protection for sustainability of agricultural systems, habitats, and rural area. In this paper, we included a docume...

Tomatoes represent the host plant for the pathogen Phytophthora infestans. Together, as plant and pathogen, create a system named by A.R.ROBINSON pathosystem [1]. The plants are known as producers of many metabolites such us therpenes, alkaloids, flavonoides and amino acids. From this point of view naturally occurring substances present in different plants can represent a continuous resource of biological agents. Late blight of potato (Phytophthora infestans Mont. de Bary) is a serious threat to potato production ...

Cruciferous vegetables are rich source of phytochemicals which play an important role as a health-protecting factor. These compounds and enzymatic systems may combat oxidative stress in the human body by maintaining a balance between oxidants and antioxidants. This is particularly important because under oxidative stress excessive formation of reactive oxygen species (ROS) can damage biomolecules, such as DNA, proteins, lipids and carbohydrates, and lead to numerous disease conditions. The enzyme superoxide dismut...

The paper deals with the removal of hydrocarbons C10-C40 from the river sediment using flotation and bacterial leaching. Flotation, as a purely mineral processing method, was used to remove a large percentage of organic pollutants. Flotation has not been applied in the cleaning of organically contaminated soils and sediments in the Czech Republic so far. The flotation collecting agent was Montanol 551. The flotation results show that the method appears as very effective as dominant proportions of the pollutants pa...

The use of marine algae in plant cultivation has been known since antiquity, but their application to reduce abiotic stress has been reported in recent years, when the use of technology based on healthy products for humans and other organisms has become a priority. In this work, we investigated the effect of a seaweed extract from the brown alga Ascophyllum nodosum (L.) Le Jolis (SuperFiftyпїЅ 0-0-8) on drought stress tolerance in Phaseolus vulgaris L. Been plants have been influenced by drought stress for a week ...

In Romania, wheat is the main crop, occupying the largest area of arable land. Convolvulus arvensis is a competitive and invasive weed, produces direct and indirect damages to which is added production of allopathic substances. Allelopathy is a natural phenomenon which refers to any direct or indirect effect, positive or negative of a plant (including microorganisms) on the other by the release of chemical compounds in the environment [13]. In most cases, influence is inhibitory, which may explain why some plants ...

The aim of this work was to determine, comparatively, the content of vitamin C (by iodometric method), polyphenols (by Folin CiocпїЅlteu assay), chlorophyll pigments, carotenes, xanthophylls (by spectrophotometric method) and the antioxidant activity (by CUPRAC method) for some frozen vegetables on the Romanian market: okra (Abelmoschus esculentus), green beans (Phaseolus vulgaris)- Serengeti variety and green peas (Pisum sativum) пїЅ Alaska variety. Frozen peas was the most rich in ascorbic acid (9.32 mg/100g) an...

The increase in the number of potentially toxic substances has led to a more complex task of determining the toxicity of water resources. This is due to an increase in the number of necessary techniques for the separation, identification and subsequent analysis of individual components. At the same time, the determination of quantitative relationships between individual components does not allow us to determine precisely whether these concentrations are sufficient to classify the water samples under study as toxic...

The research in dairy cows in mountain aria demonstrated that the arithmetic average of the mammary repose period is about 62 days. This value is very close to the desired value of cow breeders. Very high value of the coefficient of variation (57.28%) shows that we are dealing with an average resulting from compensation. This theory is supported by very large difference of about 13 days between arithmetic and probable average of dry period. Probable average is 49 days to 311 registered cows, preceded by a shorter ...

The goal of study was to develop the method of food biopreparations production based on corn extract and DDGS - liquid waste of starch and ethanol production for usage in food products as acidity regulators instead of very expensive organic acids. Processes of waste bioconversion using Lactobacillus Acidophilus were the basis for biopreparations production. There were developed the modes of cultivation of lactic acid bacteria on nutrient media, the stages of productions were determined, chemical and biochemical co...

Ostrava Lagoons belong among the most polluted areas in the Czech Republic. According to the available information, about 200 000 t of sludge from the industrial processing of crude oil during the whole 20th century were disposed there. The sludge contains high levels of organic pollutants (PAHs, PCBs, C10 - C40 hydrocarbons), including toxic metals of anthropogenic origin (As, Cd, Cu, Hg, Ni and Pb). A number of autochthonous microorganisms were isolated from the lagoon sludge. This study focuses on the biodivers...
