Abstract

Traditional methods for the enumeration of airborne fungi are slow, tedious, and rather imprecise. The possibility of using flow cytometry (FCM) for the assessment of exposure to the fungus aerosol is evaluated.

Abstract

The potential of a consortium of three basidiomycete mycelia isolated from compost to degrade polycyclic aromatic hydrocarbons (PAH) was first evaluated using a test based on decolorization of Poly R-478 dye. When pre-grown on straw, the consortium decolorized the dye by 83% in 7 days and generated a laccase activity of 663IUl−1. Its ability to degrade naphthalene was investigated in soil microcosms specially suited for this volatile PAH. The kinetic study was conducted at a maximal naphthalene concentration of 500mgkg−1 of soil. Naphthalene concentration, CO2 evolution and phytotoxicity (germination index, GI%) on Lepidium sativum seeds were monitored. The naphthalene concentration decreased by about 70% in three weeks in the presence of metabolic activity, while the GI% increased indicating reduced phytotoxicity. [Copyright &y& Elsevier]
