EVALUATION OF MICROBIOLOGICAL AIR QUALITY INSIDE REFRIGERATION CELLS IN 'AOSTA' MECHANIZED BRIGADE’S DEPENDENT REGIMENTS LOCATED IN EASTERN SICILY

摘要

Authors evaluated the microbiological quality of air inside some refrigeration cells of the “AOSTA” Mechanized Brigade Regiments’ messes in Eastern Sicily, through an active air sampling and monitoring system. They used PCA medium plates for evaluation of microbial mesophilic amounts and Malt agar medium plates for the evaluation of mycotic flora. Study results showed values of TMC within a range of 25 – 273 CFU/m3 and values of mycotic concentrations within range of 10-1720 CFU/m3. All identified mycotic species belonged to Aspergillus and Penicillium genus. Furthermore, authors tested a duster, used for routine cleaning of all examined rooms, as it certainly represented a very important contamination means.
