We have carried out some special experiments, trying to find the origin of coloured mould in the cave. For this purpose, patterns of clays were sown on the special medium. This phenomena is related to the ions fixation on negatively charges cellar wall. Among fungi from the caves there was isolated Penicillus camembertii . It is very well because now the cavers taking part in expeditions for a long time can make a Camembertii Cheese buried some milk in the cave clay.
Microorganisms are very important also as primary link of ecosystem.
Their biomass is main food for micro mites and insects. By the way that is interesting that these species were found because of the smell. Majority of diplopoda have specific secrets and these species leave on stones the smell like the camel's. According of Bitsukov some of chambers in Promezhutochnaya Cave have flower-like smell sometimes. If somebody pass by gypsum plain at basis of mountains he senses a void under his feet.
