Embodiment

[0045] Hereinafter, the present invention will be specifically described by way of examples, but the present invention is not limited to these examples.

[0046] A) Qualitative evaluation of activity in liquid and solid phases

[0047] The activity of different strains of Microbacterium genus against S. aureus ATCC 13709 has been qualitatively evaluated in solid and liquid phase (Table 1). Strains 1 to 8 belonged to the species Microbacterium dendriticum and strains 9 to 19 belonged to different species of the genus Microbacterium, but said species could not be identified.

[0048] Table 1

[0049] strain

[0050] It has now been found that activity is observed depending on the nature of the phase in which the Microbacterium strain is cultured.

Abstract

The present invention relates to the use of a bacterium of the genus Microbacterium for the production of a compound endowed with antibacterial activity.

Description

Background technique [0001] Antimicrobial resistance, the ability of microorganisms to find ways to circumvent the effects of drugs used to treat infections caused by such microorganisms, is considered a current public health problem not only because of the Bacteria are growing trend, but also due to lack of new antibiotics. [0002] Consequently, there is a growing demand for antibiotics not only because of resistance issues but also due to increasing life expectancy in the population. [0003] For example, multidrug-resistant Gram-positive bacteria (MDRGP), which continues to challenge the scientific community, involves Staphylococcus aureus, the first penicillin-resistant strain of which emerged in 50 years ago. In addition, multidrug-resistant Gram-negative bacteria (MDRGN) have also become a concern, especially drug-resistant strains of Escherichia coli (E. coli). [0004] It has never been demonstrated in the literature that strains belonging to the genus Microbacteri...
