Performed spore titres - selected 15 different looking colonies. First added glycerol to each spore stock to make up to ~ 100 ul. Diluted each colony from 10^-1 up to 10^-10. The first dilution was 10 ul of spores in 90 ul sterile water (SW) followed by the second dilution of this total 100 ul in 900 ul of SW. Spots of 10 ul of each dilution from 10^-2 to 10^-10 were plated onto LB agar (all dilutions of a spore stock on one plate). The dilutions were actually 10^-4 to 10^-12, because taking 10ul to plate is another dilution in itself. A minimum of approx. 10^-8 spores is required for the Bioassay with Candida albicans. Incubated at 30 ° for 5 days.

Gathered 73 spore stocks in preparation for the Bioassays.
Prepared the plates for the Bioassays - spotted 2 x 5 ul of undiluted spore stock (resuspended in glycerol) onto SFM agar (without Nystatin as this would inhibit Candida albicans growth). Incubated at 30 ° for 7 days.
The transformation plate fig 1, from Friday, containing BL21 pETAntA competent cells with plasmid AntGp-RFP had four colonies growing..
