Actually i want to prepare rice straw compost by lignocellulolytic bacteria,so i want to clear one thing that is it important to add cattle manure and also can we estimate the degradation capability of cellulose,lignin and xylan .And can we determine the C:N of the compost prepared without cattle manure.
Preparing a good compost of rice straw is not easier. You can add cattle dung to fasten the process of composting. You can easily determine the change in lignin, cellulose and sugar content over a period of time by following standard methods of AOAC or NREL. C and N content of any substrate can be determined and addition of cattle dung has nothing to do with it. But yes, addition of cattle dung does help in maintaining an appropriate C:N ratio which is essential for composting.
Advantage of adding cattle dung to reduce C: N ratio already explained. In similar context, use of Azolla may be tried. We observed significant difference using 1% (w/w oven dry basis) fresh Azolla during composting of rice stubble with earthworm.
