Identification of the fungi absorbing heavy metals isolated from waste deposits of zinc factories

The disposed wastes of zinc industries contain large amounts of heavy metals such as Pb2+ and Cd2+. These elements are considered as hazardous elements to human beings and other organisms. This study aims at introducing the fungal isolates that evolved to be compatible with waste deposits during the time and can absorb Pb2+ and Cd2+ions. During the spring and autumn in 2011, eight samples of se...

Biomarkers in the fossils from the Miocene-aged Chukurovo lignite, Bulgaria: sesqui- and diterpenoids

The attention is focused on the “Chukurovo” lignites of the Sofia coal-bearing province. The coal sediments are of Neogene age: petrological studies have indicated a Badenian-Sarmatian age, while the paleobotanical interpretations have indicated the Karpatian-Badenian, respectively Early-Middle Miocene boundary. Fossilized trees are common in the Chukurovo lignites, as well as petrified wood ti...
