Abstract

Listen

Marine sponges has been a large reservoir of microbial diversity, with the presence of many species specific populations as well as producing biologically active compounds, which has attracted great biotechnological interest. In order to verify the influence of the environment in the composition of the bacterial community present in marine sponges and biotechnological potential of bacteria isolated from these organisms, three species of sponges and the waters surrounding them were collected in different beaches of Rio de Janeiro, Brazil. The profile of the bacterial community present in sponges and water was obtained by PCR-DGGE technique and the biotechnological potential of the strains isolated by producing amylase, cellulase, protease and biosurfactants. The results showed that despite the influence of the environment in the composition of the microbial community, studied marine sponges shown to have specific bacterial populations, with some, showing potential in the production of substances of biotechnological applications.

Highlights

Microorganisms can be found in different habitats in marine environments, since inanimate surfaces through the formation of biofilms until living in symbiosis with macroorganisms such as, for instance, sponges (Egan et al 2008)
A source for new secondary metabolites with important biotechnological properties, because of their wider biochemical accessibility, stability and higher activity than terrestrial counterparts (Kiran et al 2014, Skariyachan et al 2014). Among these properties we can highlight the production of enzymes that are used to catalyze reactions in various industries with low environmental impact and cost of production (Beloqui et al 2008, Ortega-Morales et al 2008, Esteves et al 2013) and biosurfactants, surface active compounds having both hydrophilic and hydrophobic domain that allows them to exist preferentially at the interface between polar and non-polar media, thereby reducing surface and interface tension, widely used in industrial and environmental applications (Banat et al 2010, Sachdev and Cameotra 2013)
To better understand the ecology of sponge-bacteria association and evaluate the biotechnological potential of the microorganisms associated, our study aimed to compare the differences in bacterial communities present in sponges and in the marine water surrounding them and the capacity of strains isolated from sponges to produce different enzymes and biosurfactant

Summary

Introduction

Microorganisms can be found in different habitats in marine environments, since inanimate surfaces through the formation of biofilms until living in symbiosis with macroorganisms such as, for instance, sponges (poriferous) (Egan et al 2008). To better understand the ecology of sponge-bacteria association and evaluate the biotechnological potential of the microorganisms associated, our study aimed to compare the differences in bacterial communities present in sponges and in the marine water surrounding them and the capacity of strains isolated from sponges to produce different enzymes and biosurfactant.
