Abstract

The influence of enzymes (lyzozyme, trypsin, papain) and physical factors (hydrostatic pressure, mechanical sand grinding, extrusion in the frozen state, ultrasonic treatment) on the spores and mycelium of actinomycetes Actinomyces streptomycini B-6 and Thiobacillus vulgaris 2681 was studied. Actinomycete spores proved to be stable to trypsin and papain. Lyzozyme induced an almost complete disruption of the mycelium. The influence of hydrostatic pressure and lyzozyme on spores was the least effective. The best disruption of spores was produced by ultrasonic treatment and extrusion in the frozen state. The intensity of coloration of pigmented supernatants was the highest during ultrasonic disruption of spores.

Actinomycosis

Actinomycosis is a rare, chronic, and slowly progressive granulomatous disease caused by filamentous Gram positive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). The disease is characterised by the formation of painful abscesses in the mouth, lungs,breast or gastrointestinal tract. Discover the latest research on actinomycosis here.
