Research Abstract

There exist a considerable literatures on the allelopathic interaction among algae particularlly of plankton algae, however comparatively little is known of the allelopathic effects of aquatic biota including such plan-ts as bacteria, fungi, macrophytic benthic algae and seed plants on the growth of algal plankton. The present investigations were focused on the above mentioned allelopathic interactions controlling the algal growth by other aquatic biota. The results obtained are as follows; 1. Using a colony-inoculation method, one of the strains of Enterobacter aerogenes isolated from brackish lakes Nakanoumi and Shinjiko showed a inhibitive eff-ect of chlorophyll production of Chlorella sp.though the cell number was unaffected. The algal growth inhibit-or (AGI) produced from E.aerogenes is relatively thermostable, and from behavior of this subtance in gel filtration, paper partition chromatography, and ion-exchange chromatography, it appears that the AGI is high molecular substancesi … More ning saccharides. 2. An extracellular product (FIX) from Nocardia amarae YK1 could induced algal flocculation as well as bacterial one. Green algae Monoraphidium sp., Chlorella sp. and blue green alga Microcvstis aeruginosa were flocculated by addition of FIX produced from Nocardia, and other simil-ar biosurfactants were detected from Rhodococcus species. 3. Aspergillus fumigatus, Cladosporium sphaerosporum and Fusarium sp.showed remarkble antialgal activities. The active substance was soluble in benzene and molec-ular weight was smaller than 1000, and was thermostable under 120゜C. 4. Nymphaea tetragona, Trapa bispinosa var. iinumai and Nelumbo mucifera, showed remarkable antialagl activities, which were closely rerated to the contents of tannin and oxalic acids of the plants. 5. The sediments composed of aquatic seed plants litter cl-early inhibited the growth of planktonic microalgae, moreover the algal floral composition were markedly affe-cted with the sediments substances. The algal inhibitive effects of lake sediments may caused by its phenolic compounds such as p-coumaric acid, ferulic acid and gallic acid originated from decomposed substance of litte-rs of aquatic weeds.
