Métodos de trabajo en el mar : Laboratorio de Vigo

Abstract

Se ha perfeccionado el método de filtración sobre membrana de ésteres de celulosa. Se filtran muestras de 20 ml., añadiendo una gota de formol hacia el final, se hace pasar agua destilada y luego cloroformo (si no se deseca el filtro). La membrana se sumerge en la mezcla de alcohol y éter sobre el portaobjetos; una vez aclarada, se cubre con una solución espesa de colodión, dejando secar sin cubreobjetos y al abrigo de la humedad atmosférica. Estas preparaciones, más que para el estudio del fitoplancton, sirven para demostrar la existencia de una elevada proporción de materia finamente dividida (leptopelo) cuyo estudio escapa a las posibilidades de la microscopía. Hay que llamar la atención sobre su importancia en la alimentación de animales filtradores y sedimentadores. Cuando el fitoplancton es abundante, pequeños retazos del filtro pueden usarse para obtener cromatogramas, lo cual constituye un nuevo método de investigación. [...] Diatomea, Paralia
