Results and discussion
Any other information on results incl. tables
The mechanism of formaldehyde degradation by Pseudomonas putida is initiated by a dismutation reaction, yielding formic acid and methanol as products. Degradation of the products began after exhaustion of formaldehyde in the medium.
Applicant's summary and conclusion
- Conclusions:
- The mechanism of formaldehyde degradation by Pseudomonas putida is initiated by a dismutation reaction, yielding formic acid and methanol as products
- Executive summary:
The biodegradation of the test item was tested by a strain of Pseudomonas putida without following a guideline. The results indicate that this biodegradation is initiated by a dismutation reaction, yielding as products formic acid and methanol. The degradation of methanol and formic acid
begins after exhaustion of formaldehyde in the medium, and presents a diauxic pattern: first formic acid
is consumed followed by methanol. Moreover, cell viability, which is affected by the amount of added formaldehyde, has been determined.
