Mini-review of the concentration variations found inthe alfresco atmospheric bacterial populations

摘要: Variations in the atmospheric surface layer's culturable, and to a lesser extent, total bacteria-associated particlecharacteristics will be discussed terms of (a)their temporal variation from 2 min resolutionthrough diurnal annual periods, (b) effect ofmeteorological conditions on their abundance andsize, (c) culturable bacterial ratio, and(d) number bacteria per culturableparticle (e) survival droplet/particles, (f) general particle size distribution including aerodynamic Count MedianDiameter (CMD). Meteorological topographic thatcontrol bacteria-associatedatmospheric concentration presentedin (a) precipitation, wind direction,(c) time day, (d) sky (i.e., cloudy,sunny, rain, etc.), season, atmosphericinversion conditions. Simulation models described that supporthypotheses concentrationcycles Earth's (and perhaps other planetaryatmospheres) layer.
