Isolation And Identification Of Air Microflora In Microbiology Laboratory

CHAPTER ONE 1.0                                                       INTRODUCTIONGases, dust particles, water vapour and air contain microorganisms. There are vegetable cells and spores of bacteria, fungi and algae, viruses and protozoa cysts. Since air is often exposed to sunlight, it has a higher temperature and less moisture. So, if not protected from desiccation. Most of these microbial forms will die. Air serves as transport or dispersal medium for microorganism they occur in relatively small number in air when compared with soil or water. The microflora of air can be studied under two h…
