This paper presents the results obtained in the research conducted for the case study included in the Bachelor's Thesis. All experiments underlying this study were performed in the laboratory of Ecology and Environmental Microbiology within the Faculty of Land Reclamation and Environmental Engineering within the U.S.A.M.V. Bucharest. In this paper we present the results obtained by testing the microorganisms from the consortium present in the soil sample taken from the vegetable garden of the Zurini family from Crucea de Piatră, Călugăreni commune, Giurgiu county and the new strain of Bacillus sp. isolated. This new edaphic bacterial strain of the genus Bacillus isolated and identified by us has the ability to produce biofilms and inhibitory compounds (like antibiotics and organic volatile compounds) that inhibited the development of phytopathogenic fungi in the complex that creates the fall of seedlings in beans (Phaseolus vulgaris), root rot and hypocotyl (Pythium sp., Rhizoctonia sp., Fusarium sp.,) that are naturally present in the soil or on the beans. Also, the new edaphic bacterial strain Bacillus sp. has the ability to stimulate the germination and development of bean plants (Phaseolus vulgaris), in addition to the ability to provide protection against infection with phytopathogenic fungi from the soil.
