description Gymnodinium catenatum, a dinoflagellate that produces paralytic toxins, is one of the most studied dinoflagellate species. However, scarce information exists about its interaction with bacteria. In this study, the effect of a bacterial consortium in strains of G. catenatum was determined. Four strains of G. catenatum isolated from Bahía de Santiago, Colima; Lázaro Cárdenas, Michoacán; and Bahía Concepción and Bahía de La Paz, Baja California Sur were used. From the strain isolated from the coasts of Colima, a bacterial consortium was isolated with agar plates with GSe media that were incubated at a salinity of 34, at 24 °C in a L:D cycle of 12:12 h. Gymnodinum catenatum was cultivated in GSe media under the same conditions as the bacterial consortium. The interaction between these microorganisms was evaluated inoculating G. catenatum strains with the bacterial consortium. The maximum abundance, growth rate, chain length, toxin, and pigment profile were determined in G. catenatum with and without the bacterial consortium. In the presence of bacteria there was no clear effect on the growth, toxin profile, and toxin content in G. catenatum, but a significant increase in the chain length was observed. Changes in cell morphology were also observed. In addition, in the presence of the bacterial consortium, there was an increase in accessory pigments in most strains. Results suggest that the bacterial consortium could be a stress factor for G. catenatum and provide new perspectives on the interaction between bacteria and G. catenatum.

Gymnodinium catenatum, un dinoflagelado productor de toxinas paralizantes, es una de las especies de dinoflagelados más estudiadas, sin embargo, poco se conoce sobre sus interacciones con bacterias. En este estudio se determinó el efecto de un consorcio bacteriano en cepas de G. catenatum. Se emplearon 4 cepas de G. catenatum aisladas de Bahía de Santiago, Colima; Lázaro Cárdenas, Michoacán; Bahía Concepción y Bahía de La Paz, Baja California Sur. De la cepa originaria de la costa de Colima se aisló un consorcio bacteriano compuesto de 3 bacterias empleando placas de agar con medio GSe. Se incubaron a una salinidad de 34, a 24 °C y en un ciclo de 12:12 h L:O. Gymnodinum catenatum se cultivó en medio GSe líquido en las mismas condiciones que las bacterias. La interacción entre los microorganismos se evaluó inoculando el consorcio bacteriano en las cepas de G. catenatum. Se determinó la abundancia máxima, las tasas de crecimiento, la longitud de cadenas y el perfil de pigmentos y toxinas paralizantes en G. catenatum en presencia y ausencia del consorcio bacteriano. En presencia de las bacterias no se observó la misma respuesta en el crecimiento de las cepas de G. catenatum, ni en el perfil y contenido de toxinas, pero sí se observó un incremento significativo en el número de células en cadena. También se notaron cambios en la morfología de G. catenatum. Además, en presencia del consorcio bacteriano, en la mayoría de las cepas incrementó el contenido de pigmentos accesorios. Los resultados sugieren que el consorcio bacteriano pudiera ser un agente estresante para G. catenatum proporcionando nuevas perspectivas de interacción entre las bacterias y G. catenatum.
