This research used tomato waste as a substrate (fuel) in Single Chamber-Microbial Fuel Cells (scMFC) on small scale. The electrochemical properties were monitored, the functional groups of analyzed by Fourier Transform Infrared Spectrophotometry (FTIR) and microbiological analysis was performed electrodes order to identify microorganisms responsible for process. results show voltage peaks an el...

A novel carbapenem, SF2103A, is a strong inhibitor of various types of 3-lactamase. Equimolar concentrations of SF2103A completely inactivated the cephalosporinases of Proteus vulgaris and Citrobacter freundii and type lb and type II penicillinases mediated by R plasmids in a progressive manner. The inactivation of the two penicillinases and P. vulgaris cephalosporinase was apparently irreversi...

The antimicrobial efficacy of methanol, ethyl acetate, chloroform and butanol extracts of fungus Chaetomium cupreum was determined by employing well diffusion and broth micro-dilution techniques. Chaetomium species are the largest genus of saprophytic ascomycetous fungus, which belongs to the class Sordariomyetes and family Chaetomiaceae. Ethyl acetate and butanol extracts exhibited antibacteri...

During an evaluation of selective plating media for identification of coagulase-positive staphylococci in foods, two strains of Proteus vulgaris produced wider zones of acidity on plates containing NaCl than on those without the salt. Subsequent experiments showed that NaCl was responsible and that it also increased acid production in broth. Because P. vulgaris frequently interferes with the is...

INTRODUCTION Bacteria of the genus Proteus, which are a common cause of urinary tract infections, are divided into four species: P. mirabilis, P. vulgaris, P. penneri, and P. hauseri, and three unnamed genomospecies, Proteus 4, 5, and 6 (single-strain species P. myxofaciens was isolated from the gypsy moth). Establishing the serological classification of these species would aid in completing th...

Twelve isolates of Enterobacteriaceae (1 of Klebsiella pneumoniae, 8 of Escherichia coli, 1 of Proteus mirabilis, and 2 of Proteus vulgaris) classified as extended-spectrum beta-lactamase (ESBL) producers according to the ESBL screen flow application of the BD-Phoenix automatic system and for which the cefotaxime MICs were higher than those of ceftazidime were collected between January 2001 and...

Inhibition of Proteus vulgaris B-lactamase by a new B-lactam antibiotic, PS-5 was studied kinetically. There were two stages of inhibition. In the early stage, PS-5 inhibited the Blactamase by formation of a MICHAELIS-complex, and showed a competitive inhibition pattern with Kj-value of 0.22 uM (substrate, cephaloridine). After the formation of a MICHAELIScomplex between PS-5 and the enzyme, PS...

BACKGROUND Proteus species cause a variety of community- and hospital-acquired illnesses. Synthesis of β-lactamases is the predominant mechanism for resistance to β-lactam antibiotics. Among the β-lactamases, extended spectrum β-lactamases (ESBLs) and AmpC β-lactamases are the most common. AIM The objective of this study was to determine the occurrence of ESBL and AmpC β-lactamases in Proteus...
