In bacteria B is an essential part of signal molecules required for quorum sensing Goldbach and Wimmer, So far the mechanism of B toxicity in plants and cyanobacteria is a research matter. The biological material used were two Arthrospira platens is strains, thermophilic and vacuolated, P88 and TX98, used for the industrial cultivation by Solarium Biotechnology Company SA Chile.
The strains were regenerated and maintained according to the conditions described by Vonshak The experiment was carried out under controlled conditions of salinity 0.

The biomass or algal growth was measured daily by optical density at nm. The algal dry weight gL -1 , was measured as recommended by Vonshak At the end of the study once the biomass was measured samples were kept to perform a total nitrogen analysis using the Kjeldahl method and to determine the B by using the colorimetric method with Azomethine-H.
