Enrichment of Larval Fish Feed with Free Amino Acids and Proteins by Coating with Lactobacillus paracasei subsp. paracasei BGHN14 Homogenate

Abstract

This research aimed to test whether coating with Lactobacillus paracasei subsp. paracasei BGHN14 homogenate may increase soluble protein and amino acid amount on larval fish feed surface. Total amino acid and protein, as well as taste stimulating and growth promoting amino acid amounts were analyzed in coated feed samples. Results indicated that coating with BGHN14 homogenate increased the amount of soluble proteins and free Glycine on feed surface, as well as the availability of protein-bound (hydroxy-)Proline. This lab-scale research provides the basis for use of lactobacilli as resource efficient source of soluble nutrients for animal feedstuffs.
