The importance of biofilms in caves, the diversity microorganisms them, their mutual relationship and with substratum are among advancing research topics microbial biospeleology. This is making contribution to knowledge about at cave entrances phototrophic communities them. In that manner, from entrance zone Petnica Cave were examined. Light microscopy showed cyanobacteria exclusively dominant ...

A new chlorarachniophyte Lotharella reticulosa sp. nov. is described from a culture isolated from the Mediterranean Sea. This strain is maintained as strain RCC375 at the Roscoff Culture Collection, France. This species presents a multiphasic life cycle: vegetative cells of this species were observed to be coccoid, but amoeboid cells with filopodia and globular suspended cells were also present...

The effect of low temperatures on the survival, structure, and metabolism of Campylobacter coli SP10, a virulent strain, was investigated. C. coli became nonculturable rapidly at 20 and 10 degree C and slightly later at 4 degrees C. Incubation in a microaerobic atmosphere improved survival, but after day 8, campylobacters were detectable by direct-count procedures only. The increase in the numb...
