Characterization
This is a synthetic exponential phase promoter, created as part of the LEAP (Library of Engineered Aspergillus Promoters) project. It is based on the glaA promoter from different Aspergillus spp., and the gene was chosen based on RNA-seq data from Aspergillus niger.The consensus promoter was expected to have really high expression. This version has “noise" added to the sequence to support a hypothesis that it was possible to turn down expression of the promoter.
This promoter was characterised using an mCherry test device,<a href="https://parts.igem.org/wiki/index.php?title=Part:BBa_K3046009" target="_blank">BBa_K3046009</a>, inserted into an AMA1-based test plasmid, <a href="https://parts.igem.org/wiki/index.php?title=Part:BBa_K3046021" target="_blank_">BBa_K3046021</a>, and characterisation was done in multiple scales using a confocal microscope, a microbioreactor (BioLector, m2p-labs) for microtiter scale, in shake flasks for medium scale and in a 1 liter bioreactor for large scale.
The microtiter scale cultures were made by inoculating 107 spores in 1.5 mL minimal media,
