Utilización de biotransformados de Laminaria saccharina (L.) Lamouroux en la alimentación de la semilla de la almeja Ruditapes decussatus (L., 1758)
A production technique for single cell detritus (SCD) from Laminaria saccharina (L.) Lamouroux was developed based on the sequential action of two enzymes, endoglucanases and cellulases, and two bacteria isolated in our laboratories: CECT-5255 and CECT-5256, which have high levels of cellobiosic, pr...

| Sumario: | A production technique for single cell detritus (SCD) from Laminaria saccharina (L.) Lamouroux was developed based on the sequential action of two enzymes, endoglucanases and cellulases, and two bacteria isolated in our laboratories: CECT-5255 and CECT-5256, which have high levels of cellobiosic, proteolytic and alginolytic activity. Using this technique, L. saccharina meal is transformed into a suspension of algal cells and detritus of less than 20 m in diameter, which can easily be filtered and digested by bivalve molluscs. A feeding trial carried out with Ruditapes decussatus (L., 1758) seed clams showed that L. saccharina SCD, when used as their sole diet, got 40 % of the seed growth achieved with a microalgal diet (control diet). When the SCD was used in a mixed diet, it could substitute up to 90 % of the microalgae, with comparable or even higher growth rates than exclusive microalgal diets. |
