In order to research the relations of carbon sources to structure of PHAs, six kinds of PHAs sample were synthesized by activated sludge with six different carbon sources respectively in the aerobic-anaerobic-anoxic process. Their structures were determined by 〓HNMR、〓CNMR and GC-MS. When the carbon source was acetate, the unit composition of PHAs was 93. 91mol％ 3-hydroxybutanoic acid and 6. 09mol％ 3-hydroxypentanoic acid ; When the carbon source was propionate, the unit composition of PHAs was 28. 66mol％ HB, 63. 13mol％HV, 2. 55mol％ 2-methy-3-hydroxy-butanoic acid (2MHB) and 5. 66mol％ 2-methyl-3-hydroxypentanoic acid (2MHV); When the carbon source was 80％ butyrate and 20％ 1, 4-butanediol, the unit composition of PHAs was 65. 03mol％ HB, 28. 06mol％HV, 1. 91mol％2MHB, 2. 69mol％ 2MHV, 0.73mol％ 4-hydroxy butanoic acid (4HB), 0.78mol％ 4-methyl-3-hydroxy-pentanoic acid (4MHV), 0.80mol％ 3-hydroxyhexanoic acid ; When the carbon source was 20％ butyrate and 80％ 1, 4-butanediol, the unit composition of PHAs was 61. 39mol％ HB, 23. 01mol％HV, 4. 58mol％2MHB, 5. 97mol％ 2MHV, 0.91mol％ 4HB, 2. 37mol％ 4MHV, 1. 77mol％ HHx; When the carbon source was 60％ pentanoate and 40％glucose, the unit composition of PHAs was 41. 24mol％ HB, 58. 76mol％HV; When the carbon source was 60％ benzoate and 40％ glucose, the unit composition of PHAs was 65. 48mol％ HB and 34. 52mol％ HV.
