Characteristics of airborne actinomycete spores

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.

Surface charge properties of and Cu(II) adsorption by spores of the marine Bacillus sp. strain SG-1

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.
