[ 1 ] - Biological Removal of the Mixed Pharmaceuticals: Diclofenac, Ibuprofen, and Sulfamethoxazole Using a Bacterial Consortium

Background: The presence of pharmaceuticals at low concentrations (ng to μg) in the environment has become a hot spot for researchers in the past decades due to the unknown environmental impact and the possible damages they might have to the plantae and fauna present in the aquatic systems, as well as to the other living organisms.Objectives: The aim of t...

[ 2 ] - Technological and Probiotic Traits of the Lactobacilli Isolated From Vaginal Tract of the Healthy Women for Probiotic Use

Background: For biotechnological application, selected lactic acid bacteria strains belonging to the genera Lactobacillus (Lb) are proposed as an alternative to the antibiotics for the prevention and treatment of urogenital tract infections. Objectives: Isolating and selecting vaginal lactobacilli strains for probiotic use based on their technological and probiotic aptitudes. Materials and Meth...

[ 3 ] - Assessment of Streptococcus Salivarius ssp Thermophilus Antioxidant Efficiency and its Role in Reducing Paracetamol Hepatotoxicity

Background: Probiotics have attracted a great attention aiming to develop natural non-toxic antioxidants, because of their role in decreasing the risk of reactive oxygen species (ROS) accumulation. Objectives: The purpose of this study was to assess the antioxidant activity of a probiotic Streptococcus salivarius ssp thermophillus (St.sa) and to evaluate its protective effect against the ...

[ 4 ] - Biofilm Formation by the Hexavalent Chromium Removing Strain Streptococcus salivarius: in Vitro Approach on Abiotic Surfaces

In this study, a strain of lactic acid bacteria Streptococcus salivarius was studied for its capacity to remove hexavalent chromium (Cr (VI)) from a liquid medium and to form biofilm. Both properties are useful for using the strain in bioremediation of metal-contaminated effluents. For biofilm formation capacity, three methods were used: the tube method (TM), the Congo red agar method (CRA) and...
