By Products

2-Methylisoborneol (MIB) and geosmin produced by blue-green algae were successfully removed in a new gravel filter plant. Small amounts of sludge were sampled from the filter layer and the bacteria able to decompose MIB were isolated from the sludge samples. By-products of the MIB degradation by these bacteria were also investigated. Among these bacteria, efforts were mainly focused on Pseudomonas fluorescens. The components of cell free extracts of this bacterium were studied in order to verify the biological reactions in vitro. 2-Methylenebornane, 2-methyl-2-bornene and isomers of these compounds were found to be a part of the by-products of the MIB degradation in the gravel filter.

Toxic Blooms

Toxic blooms of several strains of blue-green algae are found in both natural and man-made freshwater lakes. Furthermore, mussels may accumulate toxic marine dinoflagellates, rendering them toxic to humans. Traditionally, the presence of algal toxins is tested by intraperitoneal injections of extracts in mice. However, toxic waterblooms and mussels can both be detected by means of freshly prepared rat hepatocytes in suspension.

Significant Growth Inhibition

Inhibitory effects of macrophytes on the growth of blue-green algae (i.e. Microcystis aeruginosa, Anabaena flos-aquae, or Phormidium tenue) were evaluated in a coexistence culture system in which concentrations of different macrophyte species were varied (i.e. Egeria densa, Cabomba caroliniana, Myriophyllum spicatum, Ceratophyllum demersum, Eleocharis acicularis, Potamogeton oxyphyllus, Potamogeton crispus, Limnophila sessiliflora, or Vallisneria denseserrulata). Coexistence assay results showed that only the macrophytes C. caroliniana or M. spicatum inhibited the growth of all blue-green algae, with the inhibitory effects of M. spicatum being stronger than those of C. caroliniana and being produced by the release of allelopathic compounds. In subsequent initial addition assays using M. spicatum with the alga M. aeruginosa, no significant growth inhibition was observed; whereas, in contrast, quasi-continuous addition assays showed strong growth inhibition by M. spicatum. These results provide the first evidence that unstable, growth-inhibiting allelopathic compounds are continuously secreted by M. spicatum.
