CC-MS of photosynthetic bacterium (PSB) treated spent liquor of Tianjin Paper Mill

The GC-MS spectrum of the spent liquor resulted from Tianjin Paper Mill tre ated with photosynthetic bacterium (PSB) has been analysed. Among the inter esting biodegradation products identified are some amino compounds and amid es. This may mean that amination and decarboxylation are possibly part of t he overall biodegradation process during the photosynthetic bacterial treat ment of the waste lignin liquor. The usual ligin organic building blocks fo rm the major biodegradation products analysed from the spectrum. Hypothetic al scheme for the formation of the identified amino compound is presented.
