In the case of bulk storage, there are two types of storage; storage in moist bulk Piles and storage in wet bulk piles.
Moist bulk piles are piles of bagasse at roughly 50% moisture content. Loose. moist bulk piles contain considerable quantities of air and will retain moisture. thus fungal and aerobic cellulolytic bacterial attack on the fiber will continue. Also, as there is no air circulation. the pile temperature will rise; favouring rapid thermophylic cellulolytic bacterial attack on the fiber. Deterioration of bagasse in such Piles is rather rapid, even though fungal attack may be suppressed by the high carbon dioxide content in the pile from
the breakdown of the sugars.
