A quantitative composition of microorganisms in the soil of "Holcim" Garadagh Cement plant (CP), wich is located on Absheron peninsula. was studied. It was found that while the number of bacteria decreases, the number of fungi as well as actinomycetes increases, when the distance to CP lessens. Among the isolated micromycetes from 12 genera - Aspergillus, Penicillium, Fusarium, Trichoderma, Cladosporium, Chaetomium, Rhisopus, Mucor, Mycella, Alternaria, Mortirella, Acremonium - toxigenic and allergenic species were detected. Isolated micromycete cultures were tested for tability to show the activity of 8 enzymes: protease, gelatinase, urease, phospholipase C, lipase, catalase, peroxidase, polyphenol oxidase. The percentage of positive tests results on the enzyme activity has shown a growth, depending on increasing distance to CP.
