Effect of Non-Ionogenic Surfactant on Cyanobacteria

This  is an absolutely innovative, interesting paper. Never before any effects of synthetic surfactants, especially non-ionic surfactants, were studied on marine cyanobacteria.

The authors discovered a series on unique facts. The non-ionic (=non-ionogenic) surfactant, namely Triton X-100, inhibited some of strains of marine cyanobacteria from the unique collection at Woods Hole Oceanographic Institution (MA, U.S.A.), a world-famous scientific institution.  

Moreover, low concentrations of the non-ionic surfactant, vice versa, stimulated the growth of some of the strains of cyanobacteria.

Both types of effects demonstrated a new environmental hazard from the surfactant as prospective pollutant. Any type of imbalance in the state of populations of phytoplankton is a bad thing.

Abstract
The non-ionogenic surfactant Triton X-100 acted differently on cyanobacteria Synechococcus WH 7805 and WH 8103: 5 mg/liter of the surfactant inhibited strain 7805 and favored the development of strain 8103. A lower concentration (0.5 mg/liter) stimulated the growth of both strains. Triton X-100 produced no effect on the motility of strain 8103 cells.
