“…The authors concluded that P. putida immobilized on WS has the potential to remove EA from air streams. 139 The adsorption of the liquid fuel DAEA, a noncarcinogenic liquid fuel used in space programmes, from dilute aqueous solution on ACs made of WS was considered by Ghanbari Pakdehi and Rezaei, 121 who demonstrated the feasibility of using WS for DAEA removal. They concluded that low concentrations of DAEA should be separated from dilute aqueous solutions to prevent environmental pollution.…”

“…Acetone is one of the organic compounds which are widely produced in number of chemical industries. Acetone compounds are high-priority toxic chemicals and listed as highly pollutants (Zare et al, 2012). Acetone with initial concentration of 3g L −1 was used as synthetic waste and electron donors in anode compartment.…”

Synthetic waste water contain organic compound can be oxidized in an anaerobic conditions in microbial fuel cell while biodegradation of Chemical Oxygen Demand (COD) takes place under anaerobic condition in anode compartment. The microorganisms for biological treatment of the organic matter were obtained from a UASFB bioreactor. In the treatment of waste water, ones COD was removed the current and power was generated and record. Also polarization curve was obtained. In cathode compartment ferocynide and potassium permanganate with several concentration were add for enhancement of proton oxidation. The performance of MFC for maximum current and power generation were obtained with 300 µM L −1 potassium permanganate as oxidizers agent. Maximum generated power and current densities were 22 mW/m 2 and 70 mA/m 2 , respectively. Active microorganisms used acetone as electron donors and COD removal was 69% at the end of process.

“…In the search of new biofilter media, loofa sponge derived from the fruit of Luffa cylindrica (LC) plant has taken attention due to its fibrous network structure which serves like an open cell foam material and provides excellent condition for growth of microorganism, which indicate that it may be a better alternative of man-made cellular and spongy materials such as polyurethane foam [24]. In many literatures, loofa has been also reported as an excellent carrier for cell immobilization [25], having recycling capability, and triggered biodegradability [26][27][28][29].…”

A laboratory-scale biofilter study was performed to treat cumene-inoculated mixed culture of bacterial community and loofa sponge (Luffa cylindrica) as support media for a period of 120 days in five distinct phases. The removal efficiency was obtained in the range of 40-85 % with maximum elimination capacity of 700 g m(-3) h(-1) at the inlet load of 1167 g m(-3) h(-1). The result demonstrated that loofa sponge is good support media for the removal of cumene at higher loading rates. Loofa sponge was characterized via chemical analysis and analytical techniques such as XRD; FTIR; XPS; and CHN, and the result obtained confirms its suitability as biofilter media. The SEM results of loofa with inoculum shows the formation of a biofilm layer on the surface of loofa. The GC-MS analysis of leachate confirms the presence of different organic compounds such as acetaldehyde and 4-hydroxy-2-oxopentanoic acids which are stable metabolites during cumene biodegradation. About 12.69 % of carbon present in inlet cumene was converted to biomass.
