Preparations of culture liquid of three Bacullus licheniformis strains (S, 103, and 60.4) and the enzymatic preparation lysoamidase from culture liquid of Lysobacter sp. strain XL1 actively lysed preliminarily autoclaved cells of gram-negative bacteria Proteus vulgaris and P. mirabilis. Living Proteus cells treated with these enzymatic preparations were lysed during their subsequent autoclaving. Inoculation of enzyme-treated Proteus cells, taken either separately or in combination with one another and polymyxin B, into a rich medium led to cell repair and restoration of viability of culture.

UI MeSH Term Description Entries
D010447 Peptide Hydrolases Hydrolases that specifically cleave the peptide bonds found in PROTEINS and PEPTIDES. Examples of sub-subclasses for this group include EXOPEPTIDASES and ENDOPEPTIDASES. Peptidase,Peptidases,Peptide Hydrolase,Protease,Proteases,Proteinase,Proteinases,Proteolytic Enzyme,Proteolytic Enzymes,Esteroproteases,Enzyme, Proteolytic,Hydrolase, Peptide
D011112 Polymyxin B A mixture of polymyxins B1 and B2, obtained from BACILLUS POLYMYXA strains. They are basic polypeptides of about eight amino acids and have cationic detergent action on cell membranes. Polymyxin B is used for treatment of infections with gram-negative bacteria, but may be neurotoxic and nephrotoxic. Aerosporin,Polymyxin B Sulfate
D011513 Proteus mirabilis A species of gram-negative, facultatively anaerobic, rod-shaped bacteria that is frequently isolated from clinical specimens. Its most common site of infection is the urinary tract.
D011514 Proteus vulgaris A species of gram-negative, facultatively anaerobic, rod-shaped bacteria that occurs in soil, fecal matter, and sewage. It is an opportunistic pathogen and causes cystitis and pyelonephritis.
D006358 Hot Temperature Presence of warmth or heat or a temperature notably higher than an accustomed norm. Heat,Hot Temperatures,Temperature, Hot,Temperatures, Hot
D001407 Bacillus A genus of BACILLACEAE that are spore-forming, rod-shaped cells. Most species are saprophytic soil forms with only a few species being pathogenic. Bacillus bacterium
D001433 Bacteriolysis Rupture of bacterial cells due to mechanical force, chemical action, or the lytic growth of BACTERIOPHAGES. Bacteriolyses
D013242 Sterilization The destroying of all forms of life, especially microorganisms, by heat, chemical, or other means.
D017077 Culture Media, Conditioned Culture media containing biologically active components obtained from previously cultured cells or tissues that have released into the media substances affecting certain cell functions (e.g., growth, lysis).
