All Rights reserved. Phototrophic microorganisms (cyanobacteria and algae) and microfungi, were identified from biofilm on the walls of the entrance of Božana Cave in west Serbia. Temperature, relative humidity and light intensity were measured, and chlorophyll a content determined. Light intensity differed from the entrance inwards. However, Chl a content was not proportional to light intensity, instead it was positively correlated to biofilm weight. Biofilm samples from two sites were also observed using a scanning electron microscope. Coccoid forms of cyanobacteria were abundant at the sampling site with the lowest light intensity, while members of the order Nostocales were predominant at the sampling site with the highest light intensity measured. Cyanobacteria were the dominant group of phototrophs colonizing cave walls (29 taxa), with the order Chroococcales prevailing (21 taxa). The most frequently documented cyanobacteria were species from genera Gloeocapsa, Scytonema, Aphanocapsa and Chroococcus. Desmococcus olivaceus and Trentepohlia aurea were the only green algae documented on cave walls. Ascomycetes were common (e.g. Alternaria, Aspergillus, Cladosporium, Epicoccum, Penicillum and Trichoderma), while zygomycetes and oomycetes were less frequent. The different color of each biofilm sample was ascribed to the presence of various species of cyanobacteria and algae. |
