Abstract/OtherAbstract:
Rock-inhabiting black fungi [also micro-colonial or meristematic fungi (MCF)] are a phylogenetically diverse group of melanised ascomycetes with distinctive morphological features that confer extensive stress tolerance and permit survival in hostile environments. The MCF strain A95 Knufia petricola (syn. Sarcinomyces petricola) belongs to an ancestral lineage of the order Chaetothyriales (class Eurotiomycetes). K. petricola strain A95 is a rock-inhabiting MCF and its growth requirements were studied using the 96-well plate-based Biolog™ System under ∼1'070 different conditions (osmotic stress, pH growth optima, growth factor requirements and nutrient catabolism). A95 is an osmotolerant, oligotrophic MCF that grows best around pH 5. Remarkably, A95 shows metabolic activity in the absence of added nitrogen, phosphorus or sulphur. Correlations could be drawn between the known nutrient requirements of A95 and what probably is available in sub-aerial systems (rock and other material surfaces). Detailed knowledge of A95́s metabolic requirements allowed formulation of a synthetic medium that supports strong fungal growth.
