Biosurfactant properties, applications and production: Recibido diciembre Aceptado marzo Aunque una amplia gama de microorganismos son capaces de sintetizar biotensoactivos, las bacterias son las principales productoras. The properties of surfactants are characterized principally by four parameters: Surfactants are synthesized chemically or biologically, in which wcidos they are called biosurfactants.

Although an extensive number of microorganisms are capable of synthesizing biosurfactants, they are mainly produced by bacteria.

Biosurfactants have advantages over chemical surfactants due to their compatibility with the environment, low toxicity and biodegradability. However, the principal disadvantage is their high production cost in some cases. In this paper the chemical and microbiological properties of surfactants and biosurfactants are described as well as biosurfactant applications, principally in the bioremediation field.

The effect of the main process variables on the production of biosurfactants is also discussed, particularly of rhamnolipids from Pseudomonas aeruginosa. Estas dos clases de biotensoactivos poseen actividad antibacteriana debido a su capacidad de solubilizar enzimas de membrana. Varios tipos de microorganismos, incluyendo bacterias, levaduras y hongos, poseen un metabolismo capaz de producir biotensoactivos Correa et al. Cuando estos sustratos son inaccesibles por su baja solubilidad, competencia con otros microorganismos u otro tipo de factor ambiental, utilizan a los biotensoactivos para disponer de la fuente bosintesis carbono.

Otros biotensoactivos biositnesis sus microorganismos productores. Microorganismos como Acinetobacter spp.

En el caso de Acinetobacter spp. Las cepas denominadas F2. En la agricultura, los biotensoactivos son aplicados debido a su actividad insecticida y herbicida. Ejemplo de esta actividad son los productos utilizados por la empresa Rhamnolipods Co.

Por ejemplo, la solubilidad del octadecano en agua es de 0. Este comportamiento es corroborado por una extensa cantidad de trabajos. Existen diversos procedimientos para el uso de microorganismos productores de biotensoactivos en los procesos de MEOR. Una de las principales ventajas de los biotensoactivos es que son compatibles con la piel, ya que no son irritantes Kleckner y Kosaric Elementos traza como hierro y manganeso modifican el rendimiento del biotensoactivo Mukherjee et al.
