Article Abstract:
Actinomycete spores were examined with respect to their aerodynamic and physical size while airborne, their release into the air and survival after collection onto agar with an impactor. Findings showed that the incubation conditions needed for the development of spores for their release into air are different from the conditions that are needed for colony growth only. It was also suggested that the culturability of the airborne actinomycete spores varies widely and is affected by several factors such as the species and the sampling flow rate.

Article Abstract:
SC-1 spores have a high affinity as well as a high capacity for copper(II). They thus have the capability for metal removal that exploits active metal precipitation and passive adsorption processes. This was concluded from an investigation of the interactions of Cu(II) with SG-1 spores. The surface of these spores was characterized in terms of surface area, surface site density and surface charge and Cu(II) adsorption by the spores was examined to measure adsorption kinetics and capacity, as well as the effect of pH.

Article Abstract:
The endospore viability assay (EVA) against parallel experiments was developed and tested by using phase-contrast microscopy and traditional heterotrophic plate counts. It was developed as a rapid alternative to culture based assays for quantifying the efficiencies of sterilization, bioburden reduction and decontamination operations and the percentages of germinable endospores embedded in arctic ice cores.
