“…2D). It may be due to the adhesive characteristics of strain OMI, since the strain was isolated from the rhizosphere of Spirodela polyrhiza 13) . Indeed, the biofilm in the bioaugmented MBR contained higher C23O gene numbers on days 10 and 16 when compared to other days (Fig.…”

“…fuliginis OMI, capable of degrading 4-t-BP via a meta-cleavage pathway and utilizing it as a sole carbon and energy source 13) , was used in the bioaugmentation experiment. Strain OMI was cultivated in 200 mL of mineral salt medium 13) supplemented with 0.5 mM 4-t-BP as the sole carbon source (MSM+4-t-BP). The bacterial cells were allowed to grow on a rotary shaker (120 r/min) at 28 ℃ until the logarithmic phase and were then harvested by centrifugation at 15,000 × g for 10 min at 4 ℃.…”

“…Therefore, this study aimed to clarify the behavior of the bacterial strain introduced into MBR in a model experimental system. In this study, a 4-tert-butylphenol (4-t-BP)-degrading bacterium, Sphingobium fuliginis OMI 13) , was bioaugmented to a lab-scale MBR to enhance 4-t-BP elimination. 4-t-BP is a model recalcitrant compound that is frequently detected in aquatic environments 14) .…”

This study demonstrated the bioaugmentation of a lab-scale membrane bioreactor (MBR) that enhanced 4-tert-butylphenol (4 -t-BP ) elimination by Sphingobium fuliginis OMI, which utilizes 4-t-BP as its sole carbon source. The control MBR, without bioaugmentation, needed an acclimation period of over 1 month to eliminate 4-t-BP with the help of indigenous 4-t-BP degraders. Contrastingly, the bioaugmented MBR removed 4-t-BP from the influent (10 -20 mg/L) to less than the detection limit (< 1 mg/L) within 7 days, and maintained 4-t-BP elimination until day 35. According to the real-time polymerase chain reaction quantifications of the catechol 2, 3-dioxygenase genes, the bioaugmented MBR maintained larger amounts of the genes until day 17 when compared to the control MBR, which indicated the survival of strain OMI in the bioaugmented MBR during the period. These results verified that MBRs had superiority for bioaugmentation as they prevented the introduced strains from washing-out. However, more frequent membrane fouling occurred in the bioaugmented MBR, which could be induced by strain OMI. The results suggested that membrane fouling is an important factor to be addressed for successful bioaugmentation in an MBR.

“…Alkylphenols are toxic compounds and are considered as endocrine disrupters that can cause various harmful effects, including reproductive effects by imitating the typical female sex hormone, estrogen in aquatic life and in humans (Ogata et al, 2013;Toyama et al, 2011). Therefore, the industrial effluents containing alkylphenols should be properly treated to remove them.…”

In the present study five different types of alkylphenols, each of the two different types of mono and poly-aromatic hydrocarbons were selected for degradation, and conversion into poly-3-hydroxybutyrate (PHB) using the Bacillus sp. CYR1. Strain CYR1 showed growth with various toxic organic compounds. Degradation pattern of all the organic compounds at 100 mg/l concentration with or without addition of tween-80 were analyzed using high pressure liquid chromatography (HPLC). Strain CYR1 showed good removal of compounds in the presence of tween-80 within 3 days, but it took 6 days without addition of tween-80. Strain CYR1 showed highest PHB production with phenol (51 ± 5%), naphthalene (42 ± 4%), 4-chlorophenol (32 ± 3%) and 4-nonylphenol (29 ± 3%). The functional groups, structure, and thermal properties of the produced PHB were analyzed. These results denoted that the strain Bacillus sp. CYR1 can be used for conversion of different toxic compounds persistent in wastewaters into useable biological polyesters.
