Evaluation of mycelial growth of Pleurotus spp. in a potato infusion-based culture medium (Solanum tuberosum)

Edible mushrooms are considered a functional food due to their diverse nutritional properties, and therefore have great economic, environmental, biotechnological, medicinal and culinary value. The mycelial growth rate in vitro of 3 strains of Pleurotus (P. agaves, P. djamor and P. ostreatus) was studied in 2 culture media: PDA 39g/L and potato infusion-based culture medium. Mycelial growth was measured for 7 days, and the growth curve was plotted. The results were analyzed with a completely randomized design, the statistical analysis was performed under ANOVA, then a Tukey test was applied. The P. djamor strain grown in potato infusion medium showed the highest growth rate, with significant differences (p < 0.05) with respect to the other treatments, P. ostreatus showed high and constant growth in both media, without significant differences, P. agaves showed the lowest growth, without significant response to the medium used.
