چکیده
Six components of new cephem antibiotics, cephabacin M1-6, were isolated from the culture filtrate of Xanthomonas lactamgena YK-431 by various types of column chromatographies and preparative reverse-phase HPLC. Their structures were determined by spectroscopic analyses and degradation studies. They consist of 7-methoxydeacetylcephalosporin C as a nucleus and a tri- to heptapeptide including a new amino acid, which is bound at the 3-position with an ester bond.

Cephabacins, new cephem antibiotics of bacterial origin. IV. Antibacterial activities, stability to beta-lactamases and mode of action.
Cephabacin F group antibiotics with a 7-formylamino substituent showed antibacterial activity against a wide variety of bacteria including beta-lactamase-producing clinical isolates and anaerobic bacteria. Cephabacin H group antibiotics without the substituent showed more potent activity against Gram-positive bacteria than cephabacin F group antibiotics, but were not active against Gram-negativ...
متن کاملIsolation, Screening and Characterization of Hyaluronidase Producing Bacteria
Hyaluronidase has a panoramic use in biotechnology processes and therapy due to its therapeutic, pathophysiological, physiological and biological importance. Since much of the preparations of hyaluronidases are from animal source (bovine and ovine testicular sources) with limited sources of microbial origin, that prompted the authors to screen and isolate a new promising bacterial strain ...

The new complex of [H2en][Cu(pydc)2].2H2O (1) (where H2en and pydc are ethylenediammonium and 2,6-pyridinedicarboxylate, respectively) was synthesized by the reaction of a mixture of ethylenediamine (en) and 2,6-pyridinedicarboxylic acid (H2pydc) in a mixture of CH3OH/H2O as solvent. This complex was fully characterized by elemental analysis, IR, UV–Vis spectroscopy as well as single-crystal X-...
متن کاملNocathiacins, new thiazolyl peptide antibiotics from Nocardia sp. II. Isolation, characterization, and structure determination.
A new group of thiazolyl peptide antibiotics, the nocathiacins, was isolated from cultured broth of Nocardia sp. The major analogs nocathiacins I-III (1-3) were purified using silica gel and Sephadex LH-20 chromatography techniques. The structures of nocathiacins I-III were determined by spectroscopic (2D-NMR, MSn) methods, and share structural similarities to glycothiohexide-alpha (4).
متن کاملIsolation, identification and characterization of new luminous bacteria from Chah Bahar Port, southern marine habitat of Iran
Coastal region of Chah Bahar port, Sea of Oman, was screened for the presence of bioluminescence bacteria for the first time. Water samples were taken from surface and subsurface layers and immediately spread on nutrient seawater complete (SWC) agar. Luminous colonies were observed after an overnight incubation at 25°C. Among twenty luminous isolates, four of them were selected for preliminary ...
