Formaldehyde is a dangerous indoor pollutant which is introduced in house by common objects such as furniture. Effective microorganisms have the very interesting ability to degrade some pollutants. Here, we tested the removal of formaldehyde and aromatic aldehydes using effective microorganisms including yeast, lactic acid bacteria, and photosynthetic bacteria. Formaldehyde was quantified by GC-MS of formaldehyde dinitrophenylhydrazone. Other aldehydes were analyzed by GC-MS. Results show that effective microorganisms remove 70-100 % of formaldehyde, benzaldehyde, and 4-methylbenzaldehyde in about a week. Experiments on chipboard panels indicate the possibility to decrease the amount of formaldehyde emission by furniture. This is the first report on the removal of formaldehyde by effective microorganisms, to our best knowledge

Abstract
Formaldehyde is a dangerous indoor pollutant which is introduced in house by common objects such as furniture. Effective microorganisms have the very interesting ability to degrade some pollutants. Here, we tested the removal of formaldehyde and aromatic aldehydes using effective microorganisms including yeast, lactic acid bacteria, and photosynthetic bacteria. Formaldehyde was quantified by GC-MS of formaldehyde dinitrophenylhydrazone. Other aldehydes were analyzed by GC-MS. Results show that effective microorganisms remove 70-100 % of formaldehyde, benzaldehyde, and 4-methylbenzaldehyde in about a week. Experiments on chipboard panels indicate the possibility to decrease the amount of formaldehyde emission by furniture. This is the first report on the removal of formaldehyde by effective microorganisms, to our best knowledgeI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
