Methods and Results: The mutant of L. delbrueckii NCIM 2365 was cultivated in shake flask containing hydrolysed cane sugar (sucrose)-based medium. The lactic acid yield and volumetric productivity with hydrolysed cane concentration up to 200 g l(-1) were in the range of 92-97% of the theoretical value and between 2.7 and 3.8 g l(-1) h(-1), respectively. The fructose fraction of the syrup produced was more than 95% when the total initial sugar concentration in the medium was higher (150-200 g l(-1)). There are no unwanted byproducts detected in the fermentation broth. Conclusions: We demonstrated that L. delbrueckii mutant Uc-3 was able to utilize glucose preferentially to produce lactic acid and fructose from hydrolysed cane sugar in batch fermentation process. Significance and Impact of the Study: These findings will be useful in the production of lactic acid and high fructose syrups using media with high concentrations of sucrose-based raw materials. This approach can lead to modification of the traditional fermentation processes to obtain value-added byproducts, attaining better process economics.</p>10afructose accumulation10ahydrolyzed cane sugar10alactic acid production10aLactobacillus delbrueckii10aMutant1 aPatil, S., S.1 aKadam, S., R.1 aPatil, S., S.1 aBastawade, Kulbhushan, B.1 aKhire, Jayant, Malhar1 aGokhale, D., V.  uhttps://library.ncl.res.in/content/production-lactic-acid-and-fructose-media-cane-sugar-using-mutant-lactobacillus-001854nas a2200301   4500008004100000020002200041022001400063245009100077210006900168260007700237520082300314653001301137653003801150100002401188700002201212700002001234700001801254700001901272700002301291700002401314700001601338700001701354700001701371700001801388700001701406700001501423856011401438       2014                        eng d  a978-1-4799-5306-6  a2164-237000aEnhancement in the field emission behavior of graphene in N-2/O-2 high vacuum ambience0 aEnhancement in the field emission behavior of graphene in N2O2 h  aEngelberg, SwitzerlandbIEEE, 345 E 47th ST, New York, NY 10017 USAcJUL3 a<p>Herein we report, pressure dependent field emission (FE) behaviour of a few-layer graphene emitter. Gas dependent FE properties have been investigated in ultra high vacuum (UHV), as well as in N-2 and O-2 ambience at base pressure similar to 1x10(-6) torr. Interestingly, the graphene emitter when operated in N-2/O-2 ambience exhibits lower turn-on field and higher emission current density, as compared to the UHV conditions. The emission current stability investigated at preset value of similar to 1 mu A over the period of more than 2 hrs is found better in the N2 ambience and is characterized by fewer fluctuations, in contrast to the behaviour in the O-2 ambience. The observed enhanced electron emission behavior in N-2/O-2 ambience is attributed to modulation of the work function of graphene emitter.</p>10agraphene10aPressure Dependent Field Emission1 aSuryawanshi, S., R.1 aKolhe, Pankaj, S.1 aGavhane, D., S.1 aPatil, S., S.1 aChavan, P., G.1 aMore, Mahendra, A.1 aLate, Dattatray, J.1 aTsujino, S.1 aGobrecht, J.1 aParaliev, M.1 aBraun, H., H.1 aGroening, O.1 aFeurer, T.  uhttps://library.ncl.res.in/content/enhancement-field-emission-behavior-graphene-n-2o-2-high-vacuum-ambience-0
