In this research, were used from Bacillus licheniformis and Bacillus subtilis (spore-forming gram positive bacteria) for single cell protein production from tuna fish viscera (Thannus tonggol). Examination was done in two laboratory and fermentor scales. The used fermentor was Continues Stirred Tank Reactor (CSTR). Influence of several parameters such as pH, temperature, rpm, and fermentation time was evaluated on SCP production process. The result showed that value of SCP was 30- 45 g/l of aliquot substrate. Growth of isolates in 35°C and pH=6.9 were more than 32°C pH=6.5. Time fermentation in lab and fermentor scales was 54h and 21h respectively. Production of SCP in rpm =600 in fermentor scale was more than rpm=300. With complementary examination, can be used from SCP produced from tuna viscera, as probiotic, in fish feed.Journal
