Growth And Chemical Components Of Spirulina Subsauce Grown With Agricultural Fertilizers At Different Nitrogen Concentrations

Abstract

The article discusses cyanobacteria of the genus Spirulina, in particular Spirulina subsalsa, and their cultivation in low-cost media using agricultural fertilizers as a source of nutrients. It is mentioned that Spirulins are widely used in various biotechnological applications due to their high content of proteins, vitamins, minerals and antioxidant pigments.

It is noted that the morphological characteristics of Spirulinas may vary due to factors such as cultivation conditions, which may lead to errors in their taxonomic identification. Despite this, its potential in medical applications is highlighted, such as in the treatment of cancer, hyperlipidemia, kidney and liver diseases, diabetes and neurodegenerative diseases.

The study describes the isolation and identification of Spirulina subsalsa from water samples from the Clavellinos reservoir, Venezuela, as well as its subsequent cultivation in media enriched with agricultural fertilizers at different nitrogen concentrations. Parameters such as population growth, biochemical composition, and pigment content of cultured cyanobacteria are evaluated.

The results show that Spirulina subsauce grown in low-cost agricultural environments has similar nutritional values to those obtained with the conventional Zarrouk medium, suggesting its potential use in the biotechnology industry and in aquaculture as feed.
