Chlorophyta and Cyanophyta are photosynthetic organisms characterized by their biochemical plasticity, which has allowed them to develop in different environments and have a faster growth rate than plants. Depending on the species and environmental conditions, these organisms can produce nitrogenous enzymes, for atmospheric nitrogen fixation; phosphatases, that solubilize phosphorus; phytohormones, that promote plant growth; and hygroscopic polysaccharides, that prevent erosion and improve soil characteristics. In this sense, the aim of this review was to analyze the available information on the use of Chlorophyta and Cyanophyta as biofertilizers and their potential application in organic food production. Multiple studies and researches were found demonstrating the advantages of these microorganisms when being used to improve plants productivity, and also at the same time, leading to sustainable agriculture that is respectful to the environment. However, their high production cost has become a limiting factor for their commercialization.
Clorofitas y cianofitas son organismos fotosintéticos que se caracterizan por su plasticidad bioquímica, lo que les ha permitido desarrollarse en diferentes ambientes y tener una tasa de crecimiento más rápida que las plantas. Dependiendo de la especie y las condiciones ambientales, estos organismos pueden producir enzimas nitrogenadas para la fijación del nitrógeno atmosférico; fosfatasas que solubilizan el fósforo; fitohormonas que promueven el crecimiento de las plantas; y polisacáridos higroscópicos que evitan la erosión y mejoran las características del suelo. En este sentido, el objetivo de esta revisión fue analizar la información disponible sobre el uso de cianofitas y clorofitas como biofertilizantes, y su posible aplicación en la producción de alimentos orgánicos. Múltiples estudios e investigaciones fueron encontrados demostrando las ventajas del uso de estos microorganismos para mejorar la productividad de las plantas, y que a su vez conducen a una agricultura sostenible respetuosa con el medio ambiente. Sin embargo, su alto costo de producción se ha convertido en un factor limitante para su comercialización.

Múltiplos trabalhos foram encontrados demonstrando as vantagens do uso desses microrganismos para melhorar a produtividade das plantas e que, por sua vez, levam a uma agricultura sustentável e respeitosa com o meio ambiente. No entanto, seu alto custo de produção tornou-se um fator limitante para sua comercialização.
