Resumen
Las algas son organismos vegetales utilizados a nivel mundial debido a que poseen diferentes usos, el Ecuador cuenta con un amplio recurso algal, el cual puede ser aprovechado de diferentes maneras, el presente trabajo tiene como objetivo cuantificar la presencia de aerobios, coliformes totales y coliformes fecales en las algas Rhodophytas (Acanthophora spicifera), Clorophytas (Codium isabelae) y Heterokontophyta (Padina durvillaei), el cual para la identificación de aerobios se aplicó el método de recuento por placas, en coliformes totales y coliformes fecales se utilizó el método convencional, así, mediante estos métodos microbiológicos se observó que las especies estudiadas en parroquia ballenita en la zona supralitoral no contienen agentes de contaminación bacteriana, la ausencia de estos microorganismos se debe a que las algas poseen metabolitos secundarios que hacen que el alga contenga propiedades antibacteriana.
Seaweeds are organisms used across the globe because of they have got multiples uses, Ecuador has got a huge resource of seaweeds, which can be exploited in different ways, this work aims to quantify the presence of aerobes, total coliforms and coliforms fecal samples in the algae Rhodophytas (Acanthophora spicifera), Chlorophytas (Codium isabelae) and Heterokontophyta (Padina durvillaei), which for the identification of aerobes was applied the method of plate count, in total coliforms and fecal coliforms the conventional method was used, thus, through these microbiological methods it was observed that the species studied in the ballenite parish in the supralittoral zone do not contain bacterial contamination agents, the absence of these microorganisms is due to the algae having secondary metabolites that make the algae contain antibacterial properties.
