摘要:
The invention refers to fungal cells, and especially to oleaginous fungal cells that have been genetically modified to produce enzymes of the pyruvate dehydrogenase bypass route to enhance their lipid production. Especially the cells are modified to over-express genes encoding pyruvate decarboxylase (PDC), acetaldehyde dehydrogenase (ALD) and/or acetyl-CoA synthetase (ACS), optionally together with a gene encoding diacylglycerol acyltransferase (DAT), or to express genes encoding PDC together with ALD and/or ACS. Methods of producing lipids, biofuels and lubricants using the modified fungi are also disclosed as well as expression cassettes useful therein.A new enzyme having phosholipid: diacylglycerol acyltransferase (PDAT)activity and a polynucleotide encoding it are also disclosed, which are useful in the lipid production.A recombinant Cryptococcus cell and its construction is described.
摘要(中):
本发明涉及真菌细胞,特别是已被遗传修饰以产生丙酮酸脱氢酶旁路途径酶以增强其脂质生产的油质真菌细胞。 特别地,细胞被修饰为过度表达编码丙酮酸脱羧酶(PDC),乙醛脱氢酶(ALD)和/或乙酰辅酶A合成酶(ACS)的基因,任选与编码二酰基甘油酰基转移酶(DAT)的基因一起,或表达编码 PDC与ALD和/或ACS。 还公开了使用改性真菌生产脂质,生物燃料和润滑剂的方法以及在其中有用的表达盒。还公开了一种新型的具有磷脂:二酰基甘油酰基转移酶(PDAT)活性的酶和编码它的多核苷酸,其可用于脂质 描述了重组隐球藻细胞及其构建。
