Popis:	Three bacterial species, namely, Bacillus licheniformis, Gordonia terrae, and Virgibacillus halophilus, were isolated from a composting aquaculture waste mixture (condensed molasses fermentation solubles and rice bran) bulked with sawdust. All isolates were thermophilic bacteria with cellulase activity. Inoculation of the compost pile with the isolated bacteria shortened the composting time by one third compared with the uninoculated condition. The quality of the compost product was assessed based on the germination percentage of Chinese cabbage (Brassica paruchinensis) in different combinations of mature compost and peat. The highest germination percentage, 99%, was obtained in the 25% compost/75% peat mixture. These results suggest that the fast conversion of aquaculture food wastes into biofertilizer by means of inoculation with thermophilic bacteria is a potential technological approach for facilitating the recycling of natural resources and reducing the impact of untreated organic waste on t...
