The aim of this study is to provide data on biological state of soil in depth, using the comparative study of general microbiota frequency and activity. For the quantitative analysis of soil microbiota, we have used soil samples for dilutions (10-1 - 10-6). The results were expressed in colony-forming units/g soil (CFU). The soil was sampling from Calimani National Park (The Oriental Carpathians) in October 2006, June and September 2007. The soil microbiota registers quantitative variations from one sample point t...

The analysis of the practical applications of the findings of the preliminary tests for the effectiveness of the disinfection treatments with high-frequency cold plasma conducted on samples collected from patrimony items and reference materials of organic nature has shown that the microbiological investigations confirm the biocide action of the HF plasma in fighting bacteria (after 45 minutes in the samples of icon wood and natural silk, 60 minutes in the cotton samples, 90 minutes in the archaeological wood and l...

Considering the benefits of intensive agriculture in our time and the negative impact of chemical fertilizers and pesticides against the environment, usage of PGPR (plant growthpromoting rhizobacteria) like biofertilizers is one of the most promising biotechnology used for growing the primary production with less quantity of chemical fertilizers. The usage of PGPR may be an alternative to organic fertilizers and can reduce the pollution and preserve the environment in the spirit of practicing an ecological agricul...
