Microbiota of Otap Head Cave
Investigation presents the assessment of species composition and structure of microbiota communities in the Otap Head Cave. Species were identified using standard approaches and cultivation methods. The abundance of algae and cyanobacteria was estimated applying 5-point Brown- Blank scale. Biodiversity of biofouling communities was revealed. Cyanobacteria were the dominant group of phototrophs colonizing cave wall and water streams. The most frequently documented cyanobacteria were species from genera Chroococcus, Gloeocapsa, Oscillatoria, Phormidium. Among micromycetes prevailed Ascomycetes (genera Aspergillus, Penicillum, Trichoderma). The development of so-called lamp flora around artificial lights was not observed. The presence of sulfate-reducing and sulfur-oxidizing bacteria was detected. It can indicate that a small circulation of sulfur occurs in cave at the present time.
