The cultivation of bacteria originated in bat guano
Petrásek, Jiří ; Elhottová, Dana ; Krištůfek, Václav ; Kováč, L.
The bat guano represents an important source of organic matter in the oligotrophic caves. The high content of chitin from the remains of digested insect in bat diet causes the slow decomposition of the guano. The bat guano deposits can be auccumulated near the bat colonies during hundreds of years. The bat guano represents unique environment with specific conditions and appropriate composition of bacterial community. In this study, the bacterial communities of the guano from Domica and Ardovská Caves (NP Slovak Karst) were investigated using plate method with six different growing media. Total numbers of cultivable aerobic bacteria in guano were determined on the solid complex medium TSBA (Becton & Dickinson]. Total numbers of cultivable anaerobic bacteria were determined on the DifcoTM Anaerobic agar and blood agar (Schaedler agar with 5% sheep blood).
