Acacia mangium is a species of flowering tree in the pea family, Fabaceae, that is native to northeastern Queensland in Australia, the Western Province of Papua New Guinea, Papua, and the eastern Maluku Islands.[2] Common names include Black Wattle, Hickory Wattle and Mangium. Its uses include environmental management and wood.[1]Acacia mangium grows up to 30 metres (98 ft) tall, often with a straight trunk. This tree is widely used in Goa in the mining industry for rehabilitation of the waste dumps as it is a drought resistant species and binds the sterile mine waste consisting of lateritic strata. Like many other legumes, it is able to fix nitrogen in the soil[3]. Acacia mangium has about 142,000 seeds/kg[4].

Chemistry

The gum contains 5.4% ash, 0.98% N, 1.49% methoxyl, and by calculation, 32.2% uronic acid[5]. The sugar composition after hydrolysis: 9.0% 4-0-methylglucuronic acid, 23.2% glucuronic acid, 56% galactose, 10% arabinose, and 2% rhamnose.
