Detoxification of phenol by common duckweed (Lemna minor L.)
Aseptic culture of common duckweed (Lemna minor L.) adsorbs and transforms phenol uniformly labelled with radioactive carbon. Most of the absorbed phenol binds with proteins and low molecular weight peptides, and a small part is transformed via ring cleavage. Labelled carbon atoms of phenol are mainly localized in the cytosol and chloroplasts. The uptake and transformation of phenol by L. minor fronds is stimulated by light. Some of the labelled organic acids, amino acids and phenol-peptide conjugates have been identified.
Keywords: detoxification,Lemna minor L, phenol, phenol-peptide conjugates.
