Aims:
The goal of the study was to develop a reliable, reproducible and rapid method of culture in order to screen a large number of fungal transformants.
Methods And Results:
The method is based upon miniaturized cell cultures and automated expression screening in microwell plates. For the method development, 50 recombinant Aspergillus vadensis clones producing feruloyl esterase B (FaeB) from Aspergillus niger were screened in 6 days. Then a panel of clones showing various behaviours was checked in flasks in order to demonstrate the reproducibility of the method. Using this method, a transformant of A. vadensis producing 1.2 g l(-1) of FaeB was selected (12-fold more than the A. niger overproducing strain).
Conclusions:
This miniaturized culture method allows to obtain reliable and reproducible results. The procedure has the advantages of being efficient, time-saving and more efficient than conventional in-flask culture screening as it can screen 800 clones per day after a culture of 3 days.
Significance And Impact Of The Study:
This method could be applied to any other fungal strain culture, enzyme activity or biodiversity screening.
