Project description:Comparison of transcription profile of Pichia pastoris cells grown on Glucose medium with Pichia pastoris cells grown on Methanol/Glycerol medium, the fermentations were done in a chemostat. 2 color experiment in reference design. Pichia pastoris reference mix [mixed pool of Pichia pastoris cells sampled from various conditions including cells grown on glycerine, glucose and methanol, on full andminimal medium, in stationary and exponential growth phase, and in different stress states]
Project description:Pichia pastoris is a widely used yeast platform for heterologous protein production. Although increasing gene dosage is a powerful strategy to improve recombinant protein production, an excess in the number of gene copies often leads to decreased product yields and increased metabolic burden. In order to find the bottlenecks of this strategy, here we present a transcriptome profile comparison of a series of Pichia pastoris strains carrying a different gene dosage of the Rhizopus oryzae lipase (Rol) as a model protein. Cells were grown on a mixture of glycerol:methanol in chemostat cultures. 2 color experiment in reference design.
Project description:The yeast Pichia caribbica shown the capability to degrade patulin by the intracellular enzymes. However, the enzymes which risponsible for the degradation process was unkonown. Transcriptome change in response to mycotoxin patulin was analyzed. The molecular mechanism of Pichia caribbica withstand patulin was revealed.
