TITLE:

Evaluation of the antimicrobial activity of a lectin from bamboo stem (Guadua angustifolia)

KEY WORDS:

Lectin; Guadua angustifolia; Antimicrobian activity

BIG AREA: Ciências Exatas e da Terra
AREA: Química
SUMMARY:

Lectins are proteins that interact with carbohydrates in a reversible and specific way, which can
assume several biological roles, including antibacterial, antifungal, anti-inflammatory, antitumor and
healing activities, activities which are related to the ability of lectins to bind to carbohydrates present
on the cell surface of target organisms, preventing their development and/or inducing a cellular
response. Brazil has the greatest forest diversity of native bamboo in the Americas and among the
identified species there is Guadua angustifolia, which is a grass with rapid development and has
several applications, including in the medicinal area with different biological activities: antitumor,
antidiabetic, anti-inflammatory, antihypertensive, antioxidant and antimicrobial. In recent years, the
study of the microbiota has aroused increasing interest from the scientific community due to its
involvement with various physiological processes and the etiologyof some pathologies. Extracts
and lectins isolated from vegetables have shown antimicrobial properties to different species of
fungi and bacteria and for this reason have been studied by several research groups. Currently,
there is a growth in research seeking to identify and isolate active substances present in these
organisms with a view to producing new drugs. Therefore, the present study aims to analyze the
effect of the lectin isolated from the stem of G.angustifolia on various microorganisms
