Streptococcus mitis has emerged as one of the leading causes of bacterial endocarditis and is related to Streptococcus pneumoniae. Antibiotic resistance has also increased among strains of S. mitis and S. pneumoniae. Phages are being reinvestigated as alternatives to antibiotics for managing infections. In this study, the two virulent phages Cp-1 (Podoviridae) and Dp-1 (Siphoviridae), previousl...

BACKGROUND Considerable works have been reported concerning the obstruction of enzymatic hydrolysis efficiency by lignin. However, there is a lack of information about the influence of lignin on the adsorption of cellulases on cellulose, along with the hydrolytic activity of the cellulases adsorbed on lignin. In addition, limited discovery has been reported about the influence of additives on c...

adsorption and desorption behavior of gd(iii) ionon macroporous weak acid resin (mwar) had been investigated.the influence of operational conditions such as contact time, initial concentration of gd(iii) ion, initial ph of solution and temperature on the adsorption of gd(iii) ion had been examined. experimental data were exploited for kinetic and thermodynamic evaluations related to the adsorpt...

Lipoteichoic acids (LTAs) have been shown to act as bacterial counterparts to the receptor binding proteins of LL-H, LL-H host range mutant LL-H-a21, and JCL1032. Here we have used LTAs purified by hydrophobic interaction chromatography from different phage-resistant and -sensitive strains of Lactobacillus delbrueckii subsp. lactis. Nuclear magnetic resonance analyses revealed variation in the ...

The recycling of lost phosphorus (P) is important in sustainable development. In line with this objective, biochar adsorption is a promising method of P recovery. Therefore, our study investigates the efficiency and selectivity of magnesium modified corn biochar (Mg/biochar) in relation to P adsorption. It also examines the available P derived from postsorption Mg/biochar. Mg/biochar is rich in...

activities of thirty bacterial strains obtained from plants rhizosphere in different areas against phytophthora drechsleri were assessed through in vitro and greenhouse experiments. dual culture and extracellular metabolites tests were used in in vitro assays. the bacterial strains inhibited growth of p. drechsleri, the highest inhibition zones was belonged to t17-4 strain with 61.904% in dual ...

Studies of the adsorption of acid dyes of the fluorane series have shown that more of the dye is adsorbed by bacteria under acid conditions than under basic or neutral conditions (Harris, 1949). The amount of dye adsorbed was also found to be related to the ionization of the dye molecule. Since both the bacterial cell and the dye anion carry negative charges, these findings suggest that as the ...
