Book Description
A number of marine microorganisms including algae, bacteria, fungi and yeasts were treated for their ability to metabolize carbaryl (1-naphthyl-N-methyl-carbamate) and 1-naphthol. None of the species included in the study were able to degrade carbaryl to a significant extent. Conversion of 1-naphthol to ether-soluble and water-soluble metabolites was observed in cultures of Culcitalna achraspora, Halosphaeria mediosetigera, Humicola alopallonella, Aspergillus fumigatus, Serratia marina, Spirrillum sp. and Flavobacterium sp. The first three organisms were more effective in degrading 1-naphthol to water-soluble metabolites than the remaining species. A very small amount of carbaryl was metabolized to water-soluble metabolites by the algae Cyclotella nana and Dunaliella tertiolecta. 1-naphthol was more toxic to the algae Cyclotella and Dunaliella than the parent compound, carbaryl. Cyclotella was more sensitive to both carbaryl and 1-naphthol than Dunaliella. Treatment with .00002M carbaryl or 1-naphthol reduced photosynthetic CO2 fixation in Cyclotella. (Author).

Book Description
In 1969 when Metabolism of Pesticides was published, it was still possible to condense the information into one volume. The continued growth of interest in the subject and the attendant volume of literature precluded such a condensation for the present volume. Consequently, this volume was prepared as an update and supplement. Readers are advised that a considerable body of literature may have been published during the time required to prepare and print the present volume.
