Bluegill-degrading bacteria were isolated from various environmental sources. <I>Brevibacillus</I> sp. BGM1 degraded bluegill efficiently at 50 °C, and its culture supernatant showed the highest peptide and amino acid concentrations as trichloroacetic acid (TCA) soluble fraction (ASF) (10.7 mg/ml) of all supernatants obtained with bluegill as a substrate. Strain BGM1 secreted a protease(s) into the medium, and the concentration of peptides and amino acids gradually increased. The fertile effect of the degraded bluegill products (DGP) on <I>Brassica rapa</I> was also investigated. The root hair density of <I>B. rapa</I> grown with DGP at a concentration of 30 μg peptides and amino acids/ml was about 1.7 times higher than when grown with the same concentration of undegraded bluegill. DGP was shown to increase root hair numbers and adventitious root formation. The results of this study suggest that a specific peptide(s) for promotion of root hair is produced from the order <I>Perciformes</I> with a protease(s) from BGM1.
