Herein we outline the antibacterial activity of amino acid containing thiazolidinediones and rhodanines against Gram-positive bacteria Staphylococcus aureus ATCC 31890, Staphylococcus epidermidis and Bacillus subtilis ATCC 6633. The rhodanine derivatives were generally more active than the analogous thiazolidinediones. Compounds of series 5 showed some selectivity for Bacillus subtilis ATCC 663...

1. In relatively low concentrations of NaCl, KCl, and CaCl(2) the rate of respiration of Bacillus subtilis remains fairly constant for a period of several hours, while in the higher concentrations, there is a gradual decrease in the rate. 2. NaCl and KCl increase the rate of respiration of Bacillus subtilis somewhat at concentrations of 0.15 M and 0.2 M respectively; in sufficiently high concen...

In this study, we have shown the microbial alkaline protease production by using isolated Bacillus subtilis. Bacillus subtilis which produces an extracellular alkaline protease was isolated from meet surface purchased from local Egyptian markets. Maximum enzyme activity was achieved when the bacterium was grown on corn steep liquor (2.0 %, w/v) instead of soybean meal (2 %) followed by casein h...

Natural competence is the ability of certain microbes to take up exogenous DNA from the environment and integrate it in their genome. Competence development has been described for a variety of bacteria, but has so far not been shown to occur in Bacillus cereus. However, orthologues of most proteins involved in natural DNA uptake in Bacillus subtilis could be identified in B. cereus. Here, we re...

A new chain of Schiff base complexes made up of Cu (II), Co (II), Cd (II),Ni (II), and Mn (II) ions derivatives were obtained by the condensation of 4-dimethyl-aminobenzaldehyde, and 4-aminoantipyrin and some amino acids. The structures of all synthesized complexes were established on the basis of their elemental analysis (UV, FTIR, and 1 HNMR). The study of X-ray crystallographic shows that th...

A phytochemical investigation of the acetone extract from the immature fruits of Garcinia cowa led to the isolation of two novel tetraoxygenated xanthones, garcicowanones A (1) and B (2), together with eight known tetraoxygeanted xanthones. Their structures were determined by spectroscopic analysis. All isolated compounds were evaluated for their antibacterial activity against Bacillus cereus T...

The antibacterial activity of Wrightia tinctoria (Roxb.) R. Br. callus extract was studied against selected pathogenic bacterial strains, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis by Agar disc diffusion method. Among the three solvents and water were used , methanol extract of callus showed higher inhibition zone against Pseudomonas aeruginosa (27 mm)...

Phytochemical screening and antimicrobial activity of chloroform, acetone and methanolic extracts of Calotropis procera (Ait.) R. Br. (Asclepiadaceae) flowers were tested against various pathogens such as Salmonella paratyphi, S. paratyphi A, Bacillus subtilis, Bacillus thuringiensis, Proteus mirabilis, Proteus vulgaris, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli. Phytoc...
