Abstract: 

This study aimed to isolate bacteria which is active during the anaerobic fermentation of poultry droppings (PD) which was collected during year (2018) from the layers farm (Al-jremkia) site which affiliated to Agriculture Directorate in Lattakia. (4) isolates were characterized using morphological and culture characteristics, and biochemical tests. These isolates were classified as follows: Pseudomonas oleovornas, Bacillus badius, Staphylococus aureus, and Methanobacterium sp. Then they were multiplied and stored as a pure starter. Two treatments from poultry droppings were prepared and each one was repeated (9) times. The first treatment was fermented without the addition of the starter (T1), while the starter was added to the second treatment. The results showed that treatment (T2) was significantly superior to treatment (T1) in the amount of biogas produced, as this amount reached (608.96) ml and (167.85) ml during a period of twenty-three days, respectively.
Keywords: poultry droppings, bacteria, starter, anaerobic fermentation.
