Abstract
Denitrification can be enhanced in the Integrated Fixed Film Activated System (IFAS) system by integrating media into the anoxic or aerobic zone. The simultaneous nitrification and denitrification (SND) in the biofilm layers has been reported in the aerobic zone of the IFAS system. In this study, two IFAS systems with Bioweb® media installed in the anoxic or aerobic reactor were operated in parallel to evaluate both anoxic denitrification or aerobic SND in the biofilm layers enhanced by fixed film media at three different nitrite and nitrate recirculation (NR) ratios of 75%, 100%, and 125%. The results revealed that both IFAS systems achieved the same organic and nitrogen removal efficiencies without statistically significant difference. The NR ratio of 125% enhanced slightly the denitrification in the anoxic zones of both systems. The media increased the anoxic denitrification at the NR ratio of 100%. The SND in the biofilm was found insignificant in both systems. It was evident that suspended-growth microorganisms stored substrates internally in the cells under anoxic conditions due to insufficient retention time. The aerobic denitrifiers including Chryseobacterium sp., Klebsiella pneumonia, and Pseudomonas aeruginosa were abundant in both IFAS systems providing aerobic denitrification with storage products as carbon sources. In summary, the denitrification in the anoxic zone and SND in the biofilm of the aerobic zone, both were enhanced by the fixed film media, did not contribute significantly to the IFAS system for the biological nitrogen removal because of microbial storage products and aerobic denitrification of several aerobic denitrifiers.

Abstract
We attempted to recycle mixed waste tea and coffee ground as alternative low-cost adsorbents for Cr(VI) removal. The adsorption parameters optimized were: initial Cr(VI) concentration (10-30 mg L-1), contact time (180 min), adsorbent dose (2.0 g L-1), initial pH (2.0), temperature (30-50 °C), and agitation speed (250 rpm). Freundlich isotherm was found better fitted with a high correlation coefficient (R2 = 0.97 for mixed waste tea and 0.92 for coffee ground) than to Langmuir model (R2 = 0.89 for mixed waste tea and 0.86 for coffee ground) for the 10-250 mg L-1 concentration range. Analysis of kinetic studies indicated that Cr(VI) adsorption by both adsorbents was consistent with the pseudo-second-order kinetic model with a good R2 and Marquardt's present standard deviation (MPSD) values. Experimental data demonstrated a sorption capacity of 94.34 mg g-1 of mixed waste tea and 87.72 mg g-1 of coffee ground. Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and Energy dispersive X-ray spectroscopy (EDS) revealed the noticeable chromium accumulation on the adsorbent surfaces after adsorption. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) studies showed that carbon and oxygen functional groups on the surface of both adsorbents involved in Cr(VI) adsorption. The adsorbents could be reused four times. Large-scale operation using 100 L of packed-bed reactor showed the breakthrough time of adsorption for mixed waste tea of 30 min in 100 mg L-1 Cr(VI) concentration. These results suggested that mixed waste tea and coffee ground be considered as alternative adsorbent for Cr(VI) removal.

Abstract
Methylobacterium species are methylotrophic bacteria that widely inhabit plant surfaces. In addition to studies on methylotrophs as model organisms, research has also been conducted on their mechanism of plant growth promotion as well as the species-species specificity of plant-microbe interaction. We employed whole-cell matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (WC-MS) analysis, which enables the rapid and accurate identification of bacteria at the species level, to identify Methylobacterium isolates collected from the rice seeds of different cultivars harvested in Japan, Thailand, and Kenya. Rice seeds obtained from diverse geographical locations showed different communities of Methylobacterium species. We found that M. fujisawaense, M. aquaticum, M. platani, and M. radiotolerans are the most frequently isolated species, but none were isolated as common species from 18 seed samples due to the highly biased communities in some samples. These findings will contribute to the development of formulations containing selected species that promote rice growth, though it may be necessary to customize the formulations depending on the cultivars and farm conditions.

Abstract
Worldwide contamination by acrylamide, a neurotoxicant and carcinogen in animals, is becoming a significant problem. We isolated three novel acrylamide-degrading bacteria from domestic wastewater in Chonburi, Thailand. Using biochemical characteristics and 16S rRNA gene sequencing, the strains were identified as Klebsiella pneumoniae, Kluyvera georgiana and Enterococcus faecalis. K. georgiana strain No. 2 was selected for further characterization due to its degradation potential of high concentrations of acrylamide at the mesophilic temperatures. The strain grew well in the presence of acrylamide at concentrations to 0.5 % (w/v), pH 5.0 to 7.0 and 37°C. Degradation of acrylamide to acrylic acid began after 30 min of cultivation as a biomass-dependent manner. Mass balance analysis revealed 92.3 % conversion of acrylamide to acrylic acid and two lower polarity compounds. Strain No. 2 degraded many aliphatic amides but not iodoacetamide and thioacetamide. High degradation level (>80 %) was found with propionamide, cyanoacetamide and acetamide. Moderate degradation was obtained in the order of formamide > butyramide > lactamide > urea while sodium azide provided 34 % degradation. These findings render this novel bacterium attractive for biodegradation of acrylamide and other aliphatic amides in the environment.

Abstract
A widespread use of acrylamide, probably a neurotoxicant and carcinogen, in various industrial processes has led to environmental contamination. Fortunately, some microorganisms are able to derive energy from acrylamide. In the present work, we reported the isolation and characterization of a novel acrylamide-degrading bacterium from domestic wastewater in Chonburi, Thailand. The strain grew well in the presence of acrylamide as 0.5% (W/V), at pH 6.0 to 9.0 and 25 degrees C. Identification based on biochemical characteristics and 16S rRNA gene sequence identified the strain as Enterobacter aerogenes. Degradation of acrylamide to acrylic acid started in the late logarithmic growth phase as a biomass-dependent pattern. Specificity of cell-free supernatant towards amides completely degraded butyramide and urea and 86% of lactamide. Moderate degradation took place in other amides with that by formamide > benzamide > acetamide > cyanoacetamide > propionamide. No degradation was detected in the reactions of N,N-methylene bisacrylamide, sodium azide, thioacetamide, and iodoacetamide. These results highlighted the potential of this bacterium in the cleanup of acrylamide/amide in the environment.

Abstract
Sphingopyxis terrae, and Sphingopyxis macrogoltabida strains 103 and 203, can degrade polyethylene glycols (PEGs). They differ in the following respects: (i) different substrate specificities (chain length) of assimilable PEG, (ii) PEG-inducible or constitutive PEG-degradative proteins, and (iii) symbiotic or axenic degradation of PEG. S. terrae was able to incorporate PEG 6000, but strain 103 could not incorporate more than PEG 4000, suggesting that the difference in assimilable PEG chain length depends on the ability to take up substrate. PEG-degradative genes (pegB, C, D, A, E and R) from these strains were cloned. Their primary structures shared a high homology of more than 99 %. The peg genes encode a TonB-dependent receptor (pegB), a PEG-aldehyde dehydrogenase (pegC), a permease (pegD), a PEG dehydrogenase (pegA) and an acyl-CoA ligase (pegE), and in the opposite orientation, an AraC-type transcription regulator (pegR). The peg operon was flanked by two different sets of transposases. These three strains contained large plasmids and the operon was located in one of the large plasmids in S. terrae. The peg genes could be detected in other PEG-degrading sphingomonads. These results suggest that the peg genes have evolved in a plasmid-mediated manner. An insertion of a transposon gene (pegF) between pegD and pegA in strain 203 was found, which caused the constitutive expression of pegA in this strain.

Abstract
The genes for polyethylene glycol (PEG) catabolism (pegB,C,D,AandE) inSphingopyxis macrogoltabidastrain 103 were shown to form a PEG-inducible operon. ThepegRgene, encoding an AraC-type regulator in the downstream area of the operon, is transcribed in the reverse direction. The transcription start sites of the operon were mapped, and three putativeσ70-type promoter sites were identified in thepegB,pegAandpegRpromoters. A promoter activity assay showed that thepegBpromoter was induced by PEG and oligomeric ethylene glycols, whereas thepegAandpegRpromoters were induced by PEG. Deletion analysis of thepegBpromoter indicated that the region containing the activator-binding motif of an AraC/XylS-type regulator was required for transcription of thepegBCDAEoperon. Gel retardation assays demonstrated the specific binding of PegR to thepegBpromoter. Transcriptional fusion studies ofpegRwithpegAandpegBpromoters suggested that PegR regulates the expression of thepegBCDAEoperon positively through its binding to thepegBpromoter, but PegR does not bind to thepegApromoter. Two specific binding proteins for thepegApromoter were purified and identified as a GalR-type regulator and an H2A histone fragment (histone-like protein, HU). The binding motif of a GalR/LacI-type regulator was found in thepegAandpegRpromoters. These results suggested the dual regulation of thepegBCDAEoperon through thepegBpromoter by an AraC-type regulator, PegR (PEG-independent), and through thepegAandpegRpromoters by a GalR/LacI-type regulator together with HU (PEG-dependent).
