dc.descriptionMangroves are found in 112 countries around the world covering approximately 160,000 km2 (Kathiresan and Bingham 2001; Mijan Uddin et al. 2014). In the United Arab Emirates (UAE), the only naturally occurring mangrove species is Avicennia marina (EAD 2016). The area occupied by these single-species mangrove forests has increased from 40 to 155 km2 between 2005 and 2014 (EAD 2016) due to cultivation, public awareness, and conservation efforts. Mangroves in the gulf coast of the UAE grow in high salinity conditions of over 40 g/kg (Smith et al. 2007) as compared to the world seawater reference salinity of 35 g/kg (Millero et al. 2008).
dc.description.abstractAvicennia marina is the only naturally occurring mangrove specie in the arid Arabian Gulf coast of the United Arab Emirates (UAE). Due to water scarcity, A. marina is a precious biomass resource for the UAE that does not require freshwater for growing and is able to grow in the Arabian Gulf high salinity conditions of over 40 g/kg. Importantly, this lignocellulosic bioresource may be used for the production of high valuable chemicals. In this manuscript, we present the first lignocellulosic composition characterization of Arabian Gulf A. marina. To do this, A. marina stem, leaves, and pneumatophore samples were collected from two locations in the United Arab Emirates and chemically characterized for sugar composition, ash content, and by-products using standard protocols. Analysis revealed that A. marina arabinan, xylan, glucan, and lignin composition ranges between 1–22, 5–18, 10–31, and 21–48 g/100g_TS (TS: total solids), respectively. The highest composition of xylan and glucan was obtained for stems and pneumatophores (45 and 38 g/100 g TS, respectively). Xylan and glucan are the polymeric precursors for the production of high-value chemicals such as furfural and hydroxymethylfurfural (HMF). Under the characterization conditions, it was obtained furfural and HMF (g/100 g_TS) in the ranges of 0.05–0.42 and 0.45–2.1, respectively.
