“…Fusobacteria, Planctomycetes, and Gammaproteobacteria (including Plesiomonas, Pseudomonas, Vibrio, and Thiothrix) were the most abundant bacteria in this system. This result was the same as that of previous studies, which reported that these bacteria were resistant to high concentrations of antibiotics using pure cultures (Messi et al, 2005;Mindlin et al, 2008). Betaproteobacteria and Bacteroidetes, which exist normally in aerobic biosystems, were also abundant, and it has been reported that they could degrade a variety of pollutants and play important roles in wastewater treatment (Dabert et al, 2001).…”

h i g h l i g h t sMBR-NF with NF concentrate recycling was tested for antibiotic-wastewater treatment. The system was effective for antibiotic production wastewater treatment and reuse. The MBR-NF process resulted in excellent water quality and a high water yield of 92%. Organic pollutants in the wastewater were almost completely retained by the NF. a r t i c l e i n f o b s t r a c tA double membrane system comprising a membrane bioreactor (MBR) combined with a nanofiltration (NF) membrane was investigated on a pilot scale for the treatment of antibiotic production wastewater over a three-month period at a pharmaceutical company in Wuxi, China. By recycling the NF concentrate, the combined MBR-NF process was shown to be effective for the treatment of antibiotic production wastewater, resulting in excellent water quality and a high water yield of 92 ± 5.6%. The water quality of the pilot-scale MBR-NF process was excellent; e.g., the concentrations of TOC, NH 4 + -N, TP were stable at 5.52, 0.68, 0.34 mg L À1 , respectively, and the values of turbidity and conductivity of the NF permeate were 0.15 NTU and 2.5 mS cm À1 , respectively; these values meet China's water quality standard requirements for industrial use (GB21903-2008). Not only were the antibiotic removal rates of spiramycin (SPM) and new spiramycin (NSPM) over 95%, the acute toxicity was also drastically reduced by the MBR-NF pilot system. The main organics in the MBR effluent were proteins, polysaccharides, and humic-like substances; they were almost completely retained by the NF membrane and further biodegraded in the MBR because the NF concentrate was recycled. The microbial community of the MBR did not significantly change with the recycling of the NF concentrate.

“…They found that some of the bacteria from Antarctic sandstone in McMurdo Valley were resistant to one or more antibiotics such as streptomycin, chloramphenicol, erythromycin, ampicillin, cycloserine and tetracycline. Multiple antibiotic resistant strains of environmental bacteria were also found in (i) the river and bay of Tillamork, Oregon (Kelch and Lee 1978), (ii) the ice core from the Greenland (Miteva et al 2004), and the Arctic permafrost subsoil in Siberia (Mindlin et al 2008). These observations implied that the environmental bacteria were probably natural reservoirs of antibiotic resistant genes.…”

Key wo r d s: Antarctic, antimicrobial, foodborne pathogen, 16S rDNA sequence.Abstract: This report describes the isolation and characterization of bacterial isolates that produce anti−microbial compounds from one of the South Shetland Islands, King George Is− land, Antarctica. Of a total 2465 bacterial isolates recovered from the soil samples, six (BG5, MTC3, WEK1, WEA1, MA2 and CG21) demonstrated inhibitory effects on the growth of one or more Gram−negative or Gram−positive indicator foodborne pathogens (i.e. Escherichia coli 0157:H7, Salmonella spp., Klebsiella pneumoniae, Enterobacter cloacae, Vibrio parahaemolyticus and Bacillus cereus). Upon examination of their 16S rRNA se− quences and biochemical profiles, the six Antarctic bacterial isolates were identified as Gram−negative Pedobacter cryoconitis (BG5), Pseudomonas migulae (WEK1), P. corru− gata (WEA1) and Pseudomonas spp. (MTC3, MA2, and CG21). While inhibitors produced by strains BG5, MTC3 and CG21 were sensitive to protease treatment, those produced by strains WEK1, WEA1, and MA2 were insensitive to catalase, lipase, a−amylase, and prote− ase enzymes. In addtion, the six Antarctic bacterial isolates appeared to be resistant to multi− ple antibiotics.

“…Antibiotic resistance genes are often located on plasmids that are able to be horizontally transferred into diverse bacterial popula− tions contributing to the widespread dissemination of antibiotic resistance in the en− vironment (Davison 1999;Michaud et al 2004). Antibiotic−resistant bacteria have also detected in cold environments such as sandstones in McMurdo valley, Antarc− tica (Siebert et al 1996); the Arctic permafrost subsoil in Siberia (Mindlin et al 2008); near Palmer Station, Antarctica (Miller et al 2009); West Antarctica King George Island (Wong et al 2011); glacier environments in the Arctic, Antarctic, Central Asia, North and South America (Segawa et al 2013).…”

Abstract:In this study, selected heavy metals resistant heterotrophic bacteria isolated from soil samples at the Windmill Islands region, Wilkes Land (East Antarctica), were character− ized. Phylogenetic analysis revealed affiliation of isolates to genera Bacillus, Lysini− bacillus, Micrococcus and Stenotrophomonas. The strains were found to be psychrotolerant and halotolerant, able to tolerate up to 10% NaCl in the growth medium. The Minimum In− hibitory Concentration of the seven heavy metals Cr, Cu, Ni, Co, Cd, Zn, and Pb was deter− mined in solid media for each bacterial strain. Gram−positive Vi−2 strain and Gram−negative Vi−4 strain showed highest multiply heavy metals resistance, and Vi−3 and Vi−4 strains showed multi−antibiotic resistance to more than a half of the 13 used antibiotics. Plasmids were detected only in Gram−negative Vi−4 strain. The bacteria were able to produce differ− ent hydrolytic enzymes including industrially important proteases, xylanases, cellulases, and b−glucosidases. High heavy metals resistance of the Antarctic bacteria suggests their potential application for wastewater treatment in cold and temperate climates. Highly sensi− tive to Cd and Co ions Vi−1, Vi−5 and Vi−7 strains would be promising for developing biosensors to detect these most toxic heavy metals in environmental samples.
