Bc. Onochieokeke et al., INFLUENCE OF ENVIRONMENTAL ADAPTATION ON THE SENSITIVITY OF MICROMYCETES TO PENTACHLOROPHENOL TOXICITY IN MICROCOSMS, The New microbiologica, 19(1), 1996, pp. 77-84
The search for fungal strains capable of pentachlorophenol degradation
led to the isolation and identification of 98 different micromycetes.
When these strains were submitted to toxicity tests in aquatic microc
osms at concentrations of 10 mgL(-1) and 100 mgL(-1) PCP, inhibition o
f growth was 57% and 36% respectively of the total isolated and identi
fied strains. Among the strains inhibited at 10 mgL(-1), 6 can serve a
s bioindicators of PCP pollution while the strains resistant can be re
garded as potential PCP biodegraders. It was confirmed that fungal str
ains isolated from sites contaminated by chemically different products
manifest different levels of sensitivity to PCP toxicity and probably
different biodegradation potentials.
