of soil organic matter content, dynamics and structure is needed for adjusting management practices, aiming the conservation of biodiversity and global ecosystem protection against climatic changes caused by anthropic intervention.
Total values of microbial biomass and bacterial and fungal counts were generally twice higher in Calcaric Phaeozems than in Verti-Stagnic Phaeozems.
Verti-stagnic Phaeozems showed, in compare with Calcaric Phaeozems, different chemical characteristics represented by high organic matter content well humified, low nitric
was found between 1.06 and 1.50 ppm. However, there is no data about the molybdenum (Mo) content of the soil ( 2 ). The natural populations of the species have a range limited to parts of Turkey and Greece and are considered to be very rare. The species has been under conservation for almost 40 years after it was listed among the plant species to be conserved at the European scale by The Bern Convention of the European Council ( 3 ). It is also considered as one of the critically endangered (CR) species in The Red List by The International Union for Conservation of

involved in producing biofuel at industrial level. The energy potential was evaluated for all 25 species. In Table 1 it is shown the biofuel amounts yield from biomass treating as well as CO 2 obtained after their burning.
One of the most strategically important options to increase share of global renewable energy market is to use biomass in energy circuit ( 1 ). But accelerated deployment of bioenergy resources can create conflicts related to land use, water resources and biodiversity conservation. From this point of view we need to raise a question if policies

metabolites mainly with antimicrobial action ( 27 , 28 ) and enzymes that could be utilized for biotechnological purposes ( 29 ).
Non-polluting methods of biocontrol can be tested with the aid of selected microbial strains, based on their antagonistic or immunity eliciting properties ( 30 , 31 , 32 ).
Further research is needed for a better understanding of microbial communities from various ecosystems, their functioning and composition, interaction between them and interaction with other groups of organisms, to improve methods of conservation of biodiversity and to

reported the conservation between animal and plant proteases that lead to the cleavage of target proteins for the execution of cell death ( 16 , 17 ). Despite their key role in the regulation and execution of the death program, no caspase homologues have been found in plant genomes. Beside this, caspase-like enzymatic activity has been found to participate in plant specific developmental processes, for example the PCD of embryo suspensor in Picea abies ( 18 ), leaf morphogenesis of Aponogeton madagascariensis ( 19 ) or tapetum development in Nicotiana tabacum and
