Abstract

The accumulation of chlorinated insecticides from the surrounding environment by micro-organisms has been described by several workers. Chacko & Lockwood (1967) observed the accumulation of DDT and dieldrin from liquid culture media by fungi, streptomycetes and bacteria; Ko & Lockwood (1968) extended these investigations to the soil environment, where fungi and streptomycetes were shown to accumulate DDT and dieldrin to above ambient concentrations. Kokke (1970) demonstrated that many bacteria from a mixed soil population accumulated DDT during growth on nutrient agar containing 0.8 μg per ml of [C]DDT. Blue-green algae exposed to DDT at 1 p.p.m. for 7 days accumulated it at levels 94 to 964 times greater than that in the surrounding medium (Gregory, Reed & Priester, 1969). Yeasts have been shown to absorb γ-hexachlorocyclohexane and dieldrin (Voerman & Tammes, 1969).
