Agricultural Bio-Stimulant Activity of Fish Protein Hydrolysate from Common Silver Belly (Gerres subfasciatus)

Abstract

Taking into account of using the fish industry wastes and for expanding the incentive to a few under used fish species, protein hydrolysates from fish proteins are being set up by a few specialists everywhere throughout the world. Fish Protein Hydrolysates (FPH) are breakdown results of enzymatic transformation of fish proteins into smaller units like peptides, which typically contain 2-20 amino acids. Their worth has been expanded by utilizing them as fluid bio compost, feed supplement and bioorganic fertilizer. From the research carried out at our laboratory, Dry fish silver belly with both microbe and enzyme acquired from cultural broth of lactobacillus species, catalyst papain demonstrated positive upgrade of development and advancement of plants tested. In view of the yield of FPH concentrates from both microbial and enzymatic hydrolysis, the pace of seedling life list in Urad dhal, green gram and okra got higher in 0.1-0.5% convergence of dry fish hydrolysate from lactobacillus treated than in the control variation. With respect to the seeds of urad dhal, green gram and okra, the germination rate and seedling energy list from treated seeds surpassed control by 19.11-128.71%. The positive effect of dry fish protein hydrolysate by microbial procedure on germination rate, seedling life record rate in 3 kinds of seeds is the reason for the improvement of protein hydrolysate item for application in crop creation utilizing dry fish squanders. The Seedling grown in 0.5% concentration of fish hydrolysates showed significant increase in seedling vigour index of Urad dhal (13.29 ± 0.12 %), Green gram (14.1 ± 0.17%) and Okra (5.39 ± 0.43 %) was recorded through one way Analysis of Variance (ANOVA). By HPLC determination amino acid results determined that protein hydrolysates process can be stopped on 7th day (643.56ppm) whereas @ 10th day amino acid decreased (326.24ppm). Results suggest that probiotic assumes a superior job in dry fish protein hydrolysates than compounds when contrasted and yield and prudent astute.
