Experiment Media and production system * Nematode concentration ( Cn ) ×103 [nematodes/mL] at day 20 E1 50% whey, B 222 E2 8.2% AM,   B 192 E3 27.6% AM,  B 160 E4 8.2% AM,    Sb1 57 E5 8.2% AM,    Sb2 166 E6 8.2% AM,    Sb3 124 E7 27.6% AM,  Sb4 200 *All media was produced at 25ºC during 20 days and enriched with yeast extract, corn oil (co) and egg yolk (ey) at several proportions in order to promote the nematode growth. All concentrations are expressed in percentage v/v or w/v depending if ingredient is liquid or solid Main differences in the media tested are mentioned: 1excess: 5.3%, 2enrichment: 1.2%, 3 2.5% co and 1.2% ey, 4 2.5% co and 1.2% ey
