Bamboos have a great economic importance due to their applications and their impact on the environment, mainly in protecting soil and watersheds. However, microbial communities associated with plantations of bamboo species grown in Cuba have not been characterized. This could help to validate its favourable environmental impact. Then, this paper aims to quantify, characterize and identify bacteria and filamentous fungi from soil in plantations of different species of bamboo. Plants, with more than 60 years of establishment from the bamboo collection in Cienfuegos Botanical Garden and young plantations of some of this species were sampled. In addition, soil samples of other plant species and uncultivated soil were included to compare the results. Microbiological analyses were circumscribed to cultivable microorganisms. It was found that the concentration of filamentous fungi was between 104 and 105 cfu/g and the bacteria concentration was between 106 and 107cfu /g, orders similar to those of other plant species sampled. We identified a total of 13 fungi genera and three bacterial families that show the diversity of soil microorganisms associated with different species of bamboo grown in Cuba. It is also the basis for further studies on its environmental impact. Keywords: bacterium, bamboo, filamentous fungi, rhizosphere
