Bacterial Decomposition of Avicennia marina Leaf Litter from Al-khor (Qatar-Arabian Gulf)

Abstract: Overall rate of bacterial decomposition of Avicennia marina L. leaves of 0.34% day^-1was recorded on dry weight basis after 256 days of in situ incubation. Initial loss of 68.45% was observed after first 108 days and additional 20.66% loss was achieved at the end of the experiment after 256 days. Decomposing leaf litter samples harbored variable mean counts of bacteria ranging from 146 x10⁶ of amylolytic bacteria to the lowest of 0.029X10⁶ of the spore formers per gram wet weight. The dominant bacterial groups during decomposition were non spore formers and were in the order amylolytic > proteolytic > cellulolytic > lipolytic > spore formers. Highest decomposition percentage was observed during warm months.
