The co-gasification of sewage sludge and palm oil empty fruit bunch(EFB) in supercritical water(SCW) was conducted at 400 °C with a pressure of over 25 MPa. This study aimed to investigate the influence of EFB addition on the syngas production and its composition. The heavy metal distribution and the leaching potential of the solid residue were also assessed. The results showed that syngas yield significantly increased with the addition of EFB into the feedstock. The cold gas efficiency(CGE) and carbon efficiency(CE) of co-gasification were higher than those of individual gasification. The actual syngas production from co-gasification of sludge and EFB was 45% higher than the theoretical total volume. The results indicated that the addition of EFB to sludge had the synergetic promotion effect on syngas production from sludge and EFB in supercritical water. This enhancement might be due to the dissolution of alkali metals from EFB and the adjustment of organic ratio. In addition, higher percentage of heavy metals were deposited and stabilized in the solid residue after SCWG. The leaching concentration of heavy metals from the solid residues was decreased to a level below the standard limit which enables it to be safely disposed of in landfill. In conclusion, the EFB addition has been proved to promote syngas production,as well as, stabilize the heavy metal in solid residues during co-SCWG.

氨肽酶是一类可以选择性剪切氨基酸残基的蛋白酶,液泡氨肽酶Y能够调控碱性氨基酸残基的剪切以及液泡的活性。本研究通过同源性比对获得酵母液泡氨肽酶Y在稻瘟病菌中的同源基因PoAPE3,利用基因敲除法获得PoAPE3基因敲除突变体(ΔPoAPE3),并构建回补体菌株进行生物学功能分析。表型测定结果表明,PoAPE3基因敲除突变体在产孢量、孢子萌发率、致病性、侵染过程等方面与野生型均无明显差异。突变体在完全培养基(CM)和稻秆培养基(SDC)上生长速率下降,且在应对胁迫剂H 2O 2时表现为更耐受,应对刚果红时表现为更敏感。以上结果表明PoAPE3参与调控稻瘟病菌的营养生长和对外界环境胁迫的应答过程。
