Summary
Staphylococci can pass through nuclear membranes with 0.6-micron pores. For sterilizing biological media, nuclear membranes with 0.1-0.3 micron pores are recommended.
Area of Science:
- Microbiology
- Filtration Technology
Context:
- Investigating the filtration of Staphylococcus aureus through nuclear membranes.
- Assessing the sterilizability and reusability of these filters.
- Utilizing S. aureus strain No. S. 593 isolated from pathological material.
Purpose:
- To examine the filtration characteristics of staphylococcal cultures through nuclear membranes.
- To determine the efficacy of sterilization and multiple use of nuclear membrane filters.
- To identify optimal pore sizes for sterilizing biological media.
Summary:
- Staphylococci were observed to permeate nuclear membranes with pore diameters up to 0.6 microns.
- Nikiforov's mixture and UV bactericidal lamps were effective for filter sterilization and drying.
- Nuclear membranes with pore diameters of 0.1-0.3 microns are preferable for biological media sterilization.
Impact:
- Provides insights into bacterial filtration limits using nuclear membranes.
- Offers practical information on sterilizing and reusing filtration membranes.
- Guides the selection of appropriate pore sizes for effective media sterilization in microbiological applications.
