Resumen
Objective: Establish the development condition of white-rot-fungi with the use of vinasse as susbtrate and zeolite and commercial agricultural lime as support. Design/methodology/approach: Pure vinasse from a sugarcane distillery was used as the main nutrient on a support of vinnase-zeolite and vinasse-lime in 1:1 proportion. The study variable was the daily radial growth (mm-day-1) of each of the four isolates on vinasse-inert culture medium. The experimental unit was glass Petri dishes of 90x15 mm realized by triplicate. A Mann-Whitney U test (using R Studio). Results: Four fungal isolates (G = Ganoderma, P= Pleurotus, Py= Pycnoporus and Tr= Trametes) were cultured growth on zeolite-vinasse and agricultural lime-vinasse and their daily radial growth was recorded. Two fungal isolates were able to develop tissue covering the petri dish in 9 days. Vinasse-zeolite was the best treatment recording a median of 2.1 mm-day-1 on isolate G and 1.6 mm-day-1 on isolated P significantly different from agricultural lime treatment according to (p< 0.05). Limitations on study/implications: All the white rot fungi strains test were performed at 28°C and minimal development conditions by the use of a coproduct of the sugarcane industry and the use of no conventional inerts. Findings/conclusions: The development of mycelia by the isolated fungi G and P on a substrate with zeolite-vinasse recorded the highest growth compared to the agricultural lime.
