Biodiversity and biotechnological potential of microorganisms from mangrove ecosystems: a review

Abstract

Mangrove forests occurring at the interface of terrestrial and marine ecosystems represent a rich biological diversity of plants, animals and microorganisms. Microbes, being an important component of the mangrove environment, not only play a very critical role in creating and maintaining this biosphere but also serve as a source of biotechnologically valuable and important products. By participating in various steps of decomposition and mineralization of leaf litter, microbes make an essential contribution to the productivity of the mangrove ecosystem. They able to recycle nutrients, produce and consume gases that affect global climate, destroy pollutants, treat anthropogenic wastes and can also be used for biological control of plant and animal pests. Microorganisms from mangrove environments are a major source of antimicrobial agents and also produce a wide range of important medicinal compounds, including enzymes, antitumor agents, insecticides, vitamins, immunosuppressants, and immune modulators. However, the phylogenetic and functional description of microbial diversity in mangrove ecosystems has not been addressed to the same extent as for other environments. Even though the mangrove ecosystem is very rich in microbial diversity, less than 5% of species have been described; in many cases neither their ecological role nor their application potential is known. Recently developed technologies in molecular biology and genetics offer great promise to explore the potential of microbial diversity. Hence, the present paper makes an attempt to review the microbial diversity in mangrove ecosystems and explore their potential applications in various fields such as agriculture, pharmaceutical, industrial, environmental and medical sciences.

Isolation, diversity, and biotechnological potential of rhizo- and endophytic bacteria associated with mangrove plants from Saudi Arabia

“…Endophytic bacteria produce industrially important enzymes such as amylases, lipases, agarases, cellulases, and proteases (Lodewyckx et al, 2002). Further, microorganisms from mangrove ecosystems are a rich source of industrially important enzymes and antibiotics (Thatoi et al, 2013).…”

Screening for Polypropylene Degradation Potential of Bacteria Isolated from Mangrove Ecosystems in Peninsular Malaysia

“…Mangrove environments are highly productive environments known to harbor a diverse variety of microorganisms [12] which play significant roles in various environmental activities and applications [13]. The high temperature, high levels of salinity, pH, and organic matter, as well as low aeration and moisture improves the substrate conditions thereby, making it conducive for the development of diverse bacteria [14].…”

Influence of physicochemical and nutritional factors on bacterial diversity in mangrove sediments along the southwest coast of Tamilnadu, India

“…important role in nutrient cycling and thereby improving the chemical environment of this ecosystem (Alongi et al 1993;Thatoi et al 2013). The free-living bacteria, actinomycetes, fungi, and yeasts were reported to have a significant role in the formation of detritus in the mangrove ecosystems (Maria and Sridhar 2002;Prakash et al 2015).…”
