Investigation of frequency and identification of air bacteria during dust storms in Lorestan province

Background: Fine dust includes and particles suspended in the air, which reduce visibility have different origins. The present study aimed to investigate abundance of air bacteria during micro storms Lorestan province using classical methods. Materials Methods: In this study, sampling was performed three cities province. Air were isolated by methods, data analysis carried out Chi-square test. relationship between meteorological parameters investigated analyzed Spearman's correlation coefficient Results: results demonstrated that 96 colonies grew on TSA medium. Moreover, %55.2 these bacteria, %44.8 yeast. Poldakhtar Khorramabad stations showed highest (%25) lowest (%8.33) frequencies. On R2A medium, 184 grew. addition, %69 %31 Kohdasht had (%34.8) (%4.3) environments, most least frequently observed isolates Bacillus Actinomycetes, microbial frequency related Poldakhter. According test, there a direct amount fine (P=0.637, r=0.026), significance inverse linear wind speed number (P=0.048, r = -0.569). Conclusion: Bacterial higher dominant environment Micrococcus, environment, Corynebacterium. pointed an effect diversity bacteria.
