Arrhenian growth thermodynamics in a marine-derived tropical Fusarium equiseti and polar Pseudogymnoascus spp. in a liquid culture system
We hypothesised that the activation energy (Ea) of growth in a marine-derived tropical strain of Fusarium equiseti and polar strains of Pseudogymnoascus spp. grown for 10 days in a liquid culture system comprised of seawater Mueller-Hinton Broth would differ across the same experimental culture temp...
