Enhanced turnover of organic matter fractions by microbial stimulation during lignocellulosic waste composting
Enhanced organic matter turnover was detected in lignocellulosic composting piles inoculated with microorganisms specifically capable of decomposing polymeric compounds. In comparison to uninoculated piles, the following results were obtained in the inoculated piles: degradation of hemicellulose,...

| description | Enhanced organic matter turnover was detected in lignocellulosic composting piles inoculated with
microorganisms specifically capable of decomposing polymeric compounds. In comparison to uninoculated
piles, the following results were obtained in the inoculated piles: degradation of hemicellulose, cellulose
and lignin were 28%, 21% and 25% respectively higher. Total organic matter, total sugars and
phenolic compounds also decreased more intensely. Greater amounts of soluble organic carbon, reducing
sugars and soluble proteins were available to the composting microbiota. Recycling of organic to
inorganic nitrogen was improved and humification was more intense and earlier attained. Microbial community
structure was also affected by inoculation. It was initially thought that these effects were due to
enzymatic capabilities of inoculants, however, microbial counts, especially those corresponding to functional
groups, revealed that inoculation induced a true stimulation of microbial growth and activity in the
entire composting microbiota which was actually responsible for all the beneficial effects reported here. |
