The Bacteriology of ''Clean Rooms'': Progress Report, 1 April - 30 September 1965

During the six-month period covered by this report (4-1-65 to 9-30-65) progress can be summarized in four different areas as follows:
1. Identification of spore formers and other heat resistant microorganisms actually recovered from fallout strips in conventional aero-space "clean room" facilities.
2. Experimental determination of dry heat resistance of the specifically identified spore formers, with particular reference to the 135 °C. for 24 hours cycle.
3. Experiments related to human contact contamination of various representative materials and simulated components.
4. Progress toward the design and construction of a small laminar downflow facility for future evaluation.
