polymyxa CS107 RESULTS: An acetoin high producing strain, design

polymyxa CS107. RESULTS: An acetoin high producing strain, designated as CS107, was newly isolated and identified as P. polymyxa based on its physiological and biochemical characteristics as well as the 16S rDNA sequence. The medium composition was optimized in shake flask fermentations by a sequential statistical experimental design. Under the optimized conditions, Ganetespib solubility dmso acetoin concentration of 30.98 g L-1 was achieved with 71.83% of theoretical glucose conversion efficiency. Fed-batch fermentation based on a suitable agitation speed was carried out in a 5 L jar, the maximum acetoin concentration of 55.3 g L-1 was obtained with the productivity of 1.32 g L-1 h-1 and the yield of 75.62%. CONCLUSION:

A new strain for efficient production of acetoin, designated as P.

polymyxa CS107, was obtained. The optimization of fermentation variables and fed-batch culture resulted in a maximum acetoin concentration of 55.3 g L-1 in 5 L jar. Copyright (c) 2012 Society of Chemical Industry”
“We previously evaluated 119 consecutive total knee arthroplasties performed by a single surgeon in eighty-six patients with use of the cemented LCS (low contact stress) mobile-bearing, rotating-platform system and an allpolyethylene patellar component. The average age of the patients Lapatinib at the time of surgery was seventy years. The patients were contacted as part of their routine follow-up and were asked to participate in this study. The purpose of the present study was to report the updated results at a minimum follow-up of twenty years.

Twenty patients (twenty-six knees) were living, and one was lost to follow-up. Three knees required a reoperation (two for periprosthetic fractures and one for infection). No component was revised as a part of the reoperations. No knee required revision since the fifteen-year follow-up evaluation. Osteolysis was present in six knees compared with only three knees at the time of the fifteen-year follow-up. One knee had radiographic signs of femoral component loosening, which was associated with osteolysis. It occurred after the fifteen-year follow-up

study. The average range of motion was from 1 of extension to 105 degrees Danusertib inhibitor of flexion. The average clinical and functional Knee Society scores were 43 and 49 points, respectively, at the preoperative evaluation and 89 and 67 points at the time of the final follow-up. We concluded that the cemented LCS rotating-platform knee performed well, with durable clinical and radiographic results at a minimum follow-up of twenty years. However, the prevalence of osteolysis continues to increase with a longer duration of follow-up in these patients.”
“BACKGROUND: The food waste produced in small cities, rural areas and small communities often coexists with agroindustrial waste, such as livestock and poultry manure, which include high levels of uric acid (UA).
