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.

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''.

Gathered 73 spore stocks in preparation for the Bioassays.

Prepared the plates for the Bioassays - spotted 2 x 5 ul of undiluted and unquantified spore stock (resuspended in glycerol) as mentioned in Barke et al (2010) onto SFM agar (without Nystatin as this would inhibit Candida albicans growth). Incubated at 30 ° for 7 days.
