for collulanes from other sources. - Mandols and reese (1965) found fungal cellulases at 300C were activo from P11 3-5-7-0t with an optimum at P11 4-5-5. Uesai and Pandey (1971) report that most cellulolytic fungi are active at pit 4-6-5. It was not Possible todhtermine the pit of the mound material due to the colouration of the solutions but In general it in higher than the comb and "lightly higher than'the soil it is constructed face (Wow and Sands 1978), Variations within the mound may Occur due to mineral deposits from evapotranspiration. Zabori (1979) found pli changes with the season in the outer layers of the mounds but the comb yAi was stable. 32-11-
7-3-1 INTRODUCTI<strong>ON</strong> 7.3 LIGNIN DDGRADATI<strong>ON</strong> The bulk of energy in plant tissues in'tontained vithin a variety of polysacchirideng sugars and lignin (SwLtt, ot n1o 1979)o PI&Ut tiesuO contains herbaceous Material 'up to 35% lignin, wood generally having higher levels than part of the food materials of ternitese (Table 7-3-1)-- Lignin therefore comprises a large Licnin in a very complex polymer, the chemistry of which in incoopletely understood (swift et al. 1979). TAgnins from different sources may differ in their properties as units are linked by different bondse They are a group of substances based on three-dimensional complex aromatic polymers. The basic unit is a phanyl propane skeleton with a hydrocarbon chain attached to a phenolic group, The chemistry of ligning i*eo the variety of different bonds, the steric interference provided by aromatic monomers with a variety of side chains, Its highly branched and folded structure and Its hydrophobic riature, hinders enzy=tic attacks resulting in lignin being the most slowly decomposed of plant cell wall components (Swift ot al. 1979). During secondary thickening lignin In laid down in the cell wall thereby strengthening it. There is controversy as to whether some degree of covalent bonding occurs between lignin and r-oolysaccharides (Swift et al. 1979), The association of lignin and cellulose, which may be largely physical, forms a mutually interpenetrating systom of polymers, with the lignin formino a Icage9 around the carbohydrates,, This aasociation protects CeIIUIOSO from attack by collulolytic enzymes (La Face and Nutting 1973), and it in thought responsible for the resistance of wood to microbial decay, except by fungi that have enzyme systms capable of depolymerising lignin an vall an the carbohydrates of *ood (Cowling 1961). 322.
