Case Study

Biodegradation Strategy of Azo Dye Acid Red 337 by B. Megaterium

Ewida A Y I, et al. Water Science, 2019, 33(1), 154-161.

Acid red 337 (AR 337) is one of the azo dyes widely used in the textile industry. However, it is recorded by the European Chemicals Agency (ECHA) as an organic substance hazardous to the aquatic environment. It is noteworthy that AR 337 can be effectively degraded by B. megaterium isolated from textile wastewater. When the inoculum volume is 10% wt./v, the solution pH is 7, and the culture temperature is 30°C, the bacteria can remove 91% of the dye with a concentration of 500 mg/L within 24 h.
Biodegradation pathways of acid red 337
· Acid red 337 dye can be completely degraded by B. megaterium and converted into small and simple aliphatic compounds.
· The azo bond is broken, forming two intermediate degradation products, 2-Trifluro methyl 5-{(aminoxy) phenyl) and 7, 8-diamino-3-{(aminoxy) sodium sulfonyl) naphthalene}-1-ol.
· The latter intermediate degradation product is further degraded into methyl propionate, methyl formate and acetic acid.
· Eventually all intermediate by-products are converted into carbon dioxide.

Adsorption Removal of Acid Red 337 Dye by Mesoporous Silica

Slatni I, et al. Environmental Science and Pollution Research, 2020, 27, 38422-38433.

Adsorption Removal of Acid Red 337 Dye by Mesoporous Silica
Acid red 337 (AR337) can be adsorbed by synthetic mesoporous silica (MS) materials. The mesoporous material is synthesized using natural clay as the silica source and Pluronic L35 as the structure directing agent. Experiments on real textile wastewater containing AR337 dye showed that using 1 g of MS per liter of wastewater eliminated 39%, 40% and 31.5% of color, TOC and chemical oxygen demand, respectively.
Adsorption mechanism for acid red 337 dye by mesoporous silica
· At pH acid, the cationic form of the AR 337 is in favor of adsorption. Thus, the mechanism of AR 337 adsorption onto MS should be an electrostatic process.
· On the other hand, the AR 337 dye changes to an ionic form with increasing pH value and the interaction between the dye and the surface of MS could be explained by H bonding between nitrogen, fluorine, oxygen, and sulfur atoms.
