This article presents a study of the efficiency and degradation pattern of samples of petroleum sludge and polluted sandy soil from an oil refinery. A bacterial consortium, consisting of strains from the genera Pseudomonas, Achromobacter, Bacillus and Micromonospora, was isolated from a petroleum sludge sample and characterized. The addition of nitrogen and(More)
Oxidative stress caused by an imbalanced metabolism and an excess of reactive oxygen species (ROS) lead to a range of health disorders in humans. Our endogenous antioxidant defense mechanisms and our dietary intake of antioxidants potentially regulate our oxidative homeostasis. Numerous synthetic antioxidants can effectively improve defense mechanisms, but(More)
The aim of this study was to investigate the antioxidant activity of the methanolic extracts of Filipendula hexapetala Gilib. aerial parts (FHA) and roots (FHR) and their potential in different model systems, as well as antimicrobial activity. According to this, a number of assays were employed to evaluate the antioxidant and antimicrobial potential of F.(More)
Assessment of heavy metal concentrations in the soil samples of urban parks and playgrounds is very important for the evaluation of potential risks for residents, especially children. Until recently, there has been very little data about urban parks pollution in Montenegro. To evaluate the sources of potential contamination and concentration of heavy(More)
Two basic proteins, HLP-1 and HLP-2, were isolated from brewer's barley grain (Hordeum vulgare L.) and characterized as glycoproteins with molecular masses of 16 and 13 kDa and pI values of 7.4 and 8.8, respectively. They could bind sugars, metal ions, and both hydrophobic and hydrophylic molecules of low molecular mass. These characteristics may be related(More)
The bifidogenic effect of an infant formula supplemented with inulin and fructooligosaccharides (4.0 g/l) was examined clinically and in vitro, and compared that of mature breast milk. In a 28-day clinical study, fecal samples of 21 infants, divided into two groups: one receiving the infant formula and the other breast milk, were microbiologically and(More)
The capacity of fungus Aspergillus niger to degrade anionic surfactants (AS) and coproduce the detergent compatible enzymes in a liquid Czapek-Dox medium supplemented with 0.3% powder detergent Merix (Henkel, Serbia) was examined in this study. The fungus was isolated from wastewater of Lepenica River (Kragujevac, Serbia), at a place where municipal(More)
The ability of native wild isolate Penicillium cyclopium Westling to degrade commercial detergent Merix (Henkel, Serbia) as well as the influence of detergent on activities of some fungal enzymes was in the focus of this study. The fungus was isolated from the riverbed of Western Morava (Čačak, Serbia), at a place where municipal wastewater discharged into(More)
