A preparation of lysozyme from a freshwater bivalve, Unio pictorum, has been isolated by sorption to chitin, and its physicochemical properties have been studied. An assessment of the sensitivity of 48 strains of rhodococci, belonging to the species Rhodococcus rubber, R. luteus, and R. erythropolis (Specialized Collection of Alkanotrophic Microorganisms of the Institute of Ecology and Genetics of Microorganisms, Ural Division of the Russian Academy of Sciences), which were isolated from diverse natural waters, to lysozyme of the mollusk Unio pictorum demonstrated that the three species differ in their sensitivity to its effects. The high resistance of rhodococci to lysozyme is indicative of their considerable permanence in hydrobiocenoses (and, therefore, ability to maintain self-purification of microbiocenoses from hydrocarbons). 相似文献

It was shown that fetal form of haemoglobin (Hb) is mainly connected with membrane of peripheral red blood corpuscles. Membrane-bound haemoglobin has relatively high affinity to O2, low Hill's coefficient, much higher peroxidase activity in comparison with cytosolic Hb. 相似文献

The physicochemical and biological properties of the low-molecular antibacterial peptide isolated from the cultivation medium
of Staphylococcus warneri IEGM KL-1 were studied. The peptide was obtained in a homogenous state by the methods of ultrafiltration, ion exchange, and
reversed phase chromatography. The peptide contained a substantial quantity of cationic and hydrophobic amino acid residues
and an uncommon amino acid lanthionine. The molecular mass of the peptide was 2999 Da. A bactericidal effect of the isolated
peptide on the cells of S. epidermidis 33 was exhibited in a wide pH range, being completely preserved upon heat treatment. In accordance with the characteristics,
origin, and species affiliation of the producer, the peptide was named warnerin. The available data allow us to consider warnerin
as a new representative of the family of lantibiotics, promising antibiotic agents of microbial origin. 相似文献
