| Abstract | Poultry waste can be hydrolyzed using microorganisms to obtain useful amino acids for agriculture processes. This research treated poultry waste by applying beneficial microbial consortia. Microorganisms were obtained from Brassica oleracea (commonly known as cabbage) and Jungia rugosa (widely known as matico de puna) plants. Each sample was sent to the laboratory for gender, species, and concentration identification. Poultry waste (feathers, offal, blood) and a liquid solution made up of water, molasses, and microorganisms were placed inside plastic tanks. Four treatments were established (T1, T2, T3, and T4). T1 and T3 were composed of 80% water, 10% molasses, and 10% microorganisms; T2 and T4 were composed of 70% water, 20% molasses, and 10% microorganisms. The contents in each tank were periodically stirred for one month. Sixteen microorganisms were identified in each sample. In each treatment, nine essential and nine non-essential amino acids were found in different concentration levels. It is assumed that indigenous microbial consortia benefit the hydrolysis of poultry waste. Furthermore, the type and content of amino acids are related to the microbial activity of each consortium. |
