Abstract

The waste (heads, bones, skin, scales, fins and guts) of Tilapia (Oreochromis niloticus) was hydrolyzed by concentrated H2SO4 acid, and then the supernatant was obtained after centrifugation and filtration. The supernatant was divided to three samples. First sample, only the acid-hydrolyzed Nile tilapia fish wastes supernatant, second sample the acid-hydrolyzed Nile tilapia fish wastes supernatant including 1% glucose and the third sample which was the acid- hydrolyzed Nile tilapia fish wastes supernatant including 2% glucose. After that, the samples were inoculated with Lactobacillus plantarum bacteria and incubated at 30˚C. For the analysis, four parameters were tested every eight hours. These parameters were pH, lactic acid concentration, glucose concentration and the growth of bacteria. The results of the study indicated that the productivity of lactic acid in the first sample was not effective 5.5 g/L but those in second and third sample were 12.28 g/L and 16.1 g/L respectively. In addition the results showed that the bacterial growth in the second sample was much higher than the other samples. For the germination test and fertilizing ability test, the pH of the fermented broth was equalized by adding 1 M NaOH and diluted by distilled water to reduce the salinity to 10, 6 and 3%. The best results were obtained from the diluted solutions at both 3 and 10% salinities as the GI% were 95 and 75 respectively. According to the results of the germination test, a hydroponic culture system was held using barley seeds to study the fertilizing ability of the final fermented broth. The diluted solution at 10% salinity was used against distilled water as a control. The results showed that the stem length of barley was 10.3 cm after 10 days culture on the diluted fermented broth, which was better than that (8.7 cm) of the control .
