[Antibiosis shown by a strain of Byssochlamys nivea Westling, 1909. II. Activity spectrum]. 1975

G Percebois

A strain of Byssochlamys nivea cultivated in a liquid medium (Saccharose: 50 g: NaNo3: 2 g; KH2PO4: 1 g; KCL: 0.5 g; MgSO4, 7H2O: 0.5 g; water to 1000 ml) produces, at 24 degrees C, an antibiotic substance which appears after several days of growth (10-12 days). Among 43 strains of Bacteria Gram (minus) belonging to 10 genera none was resistant. The most was susceptible, save Pseudomonas aeruginosa, Serratia marcescens, Moraxella glucidolytica. On the the great bulk of the Bacteria (Gram +) tested was little influenced, except certain strains of Bacillus. The filtrate is ineffectual against Mycobacteria and Fungi (yeast or mould) at the concentration used. This substance seemed to be different of those produced by Byssochlamys fluva (byssochlamic acid) and by some species of Paecilomyces (P. varioti, P. persicinus, P. elegans, P. variabilis, P. fusidioides).

UI MeSH Term Description Entries
D009016 Moraxella A genus of gram-negative, aerobic bacteria occurring as rods (subgenus Moraxella) or cocci (subgenus Branhamella). Its organisms are parasitic on the mucous membranes of humans and other warm-blooded animals.
D009161 Mycobacterium A genus of gram-positive, aerobic bacteria. Most species are free-living in soil and water, but the major habitat for some is the diseased tissue of warm-blooded hosts. Mycobacteria
D011550 Pseudomonas aeruginosa A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection. Bacillus aeruginosus,Bacillus pyocyaneus,Bacterium aeruginosum,Bacterium pyocyaneum,Micrococcus pyocyaneus,Pseudomonas polycolor,Pseudomonas pyocyanea
D004352 Drug Resistance, Microbial The ability of microorganisms, especially bacteria, to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).

D004718 Saccharomycetales An order of fungi in the phylum Ascomycota that multiply by budding. They include the telomorphic ascomycetous yeasts which are found in a very wide range of habitats. Budding Yeast,Endomycetales,Endomycopsis,Yeast, Budding,Budding Yeasts,Endomycetale,Endomycopses,Saccharomycetale,Yeasts, Budding
D005516 Food Microbiology The presence of bacteria, viruses, and fungi in food and food products. This term is not restricted to pathogenic organisms: the presence of various non-pathogenic bacteria and fungi in cheeses and wines, for example, is included in this concept. Microbiology, Food
D005658 Fungi A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies. Fungi, Filamentous,Molds,Filamentous Fungi,Filamentous Fungus,Fungus,Fungus, Filamentous,Mold
D000898 Antibiosis A natural association between organisms that is detrimental to at least one of them. This often refers to the production of chemicals by one microorganism that is harmful to another.

D001203 Ascomycota A phylum of fungi which have cross-walls or septa in the mycelium. The perfect state is characterized by the formation of a saclike cell (ascus) containing ascospores. Most pathogenic fungi with a known perfect state belong to this phylum. Ascomycetes,Cochliobolus,Sclerotinia,Ascomycete,Ascomycotas,Sclerotinias
