The Amazon rainforest has great biodiversity of species, including animals,
plants and microorganisms. Many of these microorganisms are not yet known,
as well as some of the potential uses and properties of these. Among these are
the endophytic microorganisms who live inside the plants, many of them
showing the same properties of the host. The plant “jambu” Acmella ciliata is
known for its antimicrobial, antifungal properties among others, and is used in
food and natural medicine in the Amazon region. For the isolation of
endophytes, first held low-level disinfection of the twigs and leaves of the
plant Acmella ciliata, sow and incubate the pieces of this plant material during
15 days at 28ºc. The isolated microorganisms were evaluated in trials of
antagonism (Fusarium decemcellulare and Colletotrichum gloeosporioides) and
antimicrobial activity (Streptococcus pyogenes and Candida parapsilosis). A
total of 104 were isolated endophytic microorganisms (bacteria, filamentous
fungi and yeasts), of this universe, 22 filamentous fungi and 16 bacteria showed
inhibition of growth of plant pathogens, and six bacteria showed antimicrobial
activity for Streptococcus pyogenes and Candida parapsilosis. Was shown that
the endophytic microorganisms isolated from plant Acmella ciliata produce
metabolites with antimicrobial and antifungal activity.
