We tested biosorcion of chromium (VI) using lemon rind, citrus limonium, treated. The original lemon rind passes first through a stage of desmetoxilación with sodium hydroxide solution, 0.2M, pH 10, and in a second stage is subject to a process of crosslinking with solution diclorurm calcium, 0.2M, pH 2. The tests showed that chromium (VI) can be removed from its aqueous solutions, up to 75% of its initial concentration in twenty minutes.

The study consists of the treatment of the pumping water of fish flour industry. The addition oí microorganisms in presence of ferric sulphate is managed to destabilize the system, obtainig that a watery solution "drains" towards the inferior part, floating solid free water particles. This behavior probably is due to the destruction of the substances that are in the different interphases when they are consumed by the microorganisms. The ferric sulfato, besides to give average acid for the reproduction of the microorganisms also contributes positive charges to the system which interacts with the acuatic system.

Los alimentos funcionales o fitoquímicos tienen diversos beneficios en la prevención de enfermedades y contribuyen a reducir ciertas enfermedades crónicas. Se presenta el siguiente articulo como contribución para el desarrollo de esta nueva área de investigación.

The yacon root is a member of the sunflower family. The roots of yacon has inuline. lnuline is a polyfructosane, which helps to moderate blood sugar levels !pass through the digestive tract unmetabolized). Yacon therefore has considerable value to dieters and people with diabetes. The quantitative analysis shows mineral macronutrients INa, K, Mg, Ca, PI. and micronutrients IFe, Zn, Mn). The qualitative analysis shows very importan! secondary metabolites lamino acids, carbohydrate, reducing sugars, flavonoides)
