    摘要: The present invention relates to a method of screening for an improved enzyme variant, said method comprising the steps of: (i) providing a recombinant host cell capable of sporulating comprising a polynucleotide encoding a sporulation factor and a polynucleotide encoding an enzyme variant which are operably linked to an inducible promoter; (ii) culturing the host cell under conditions suitable to induce the formation of spores; (iii) culturing the spores obtained in step (ii) in a medium containing a substrate for the enzyme variant; and (iv) determining the activity of the enzyme variant.

    摘要: The invention provides methods of screening a microbial host cell for a property of interest in a microfluidic device, the method comprising the steps of: a) transforming a d-alanine racemase-deficient microbial host cell with a polynucleotide construct comprising: i) one or more polynucleotide region providing the property of interest when present in the host cell, and ii) at least one polynucleotide region complementing the d-alanine racemase deficiency when present in the host cell; and b) screening the transformed host cell for the property of interest in the microfluidic device in the absence of externally provided d-alanine.
