Dudhgara, Bhavsar Sunil, Ghelani AnjanaIn the present study, alkaline protease producing thermophilic Bacillus cohniiU3 strain was isolation from Unnai hot spring, India. The maximum production of protease (344 U/mL) was reported after 72 h of inoculation at 50°C in shake flask culture using the gelatin casein medium. The protease was found to remain active up to 96 h and production was growth dependent. The … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 23 Jul 2015 · 7,340 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Food Additives Nitrite and Nitrate and Microbiological Safety of Food ProductsStefanie Müller-Herbst, Anna Mühlig, Jan Kabisch et al.In Germany, raw sausages are typically produced according to a technology referred to as hurdle technology (Leistner, 2000). The combination of several stressful conditions should successfully inhibit growth and survival of pathogenic bacteria, which can be regularly found in raw pork or beef material (Mataragas et al., 2008; Rhoades et al., 2009). Hurdles applied during raw sausage fermentation are the … …Current Research in Microbiology, Vol. 6, Issue 1 · 29 Jun 2015 · 10,382 accessesView PDF Cite

Research ArticleOpen accessIn the abstractScreening of Yeast Strains for Pectinolytic Activity: Effects of Different Carbon and Nitrogen Sources in Submerged FermentationsMustafa Oskay, Hüsniye Tansel YalçinTwenty yeast strains were screened for pectinolytic activity, among the strains, only nine were positive for pectinase production. The best strain was Kluyveromyces marxianus NRRL-Y-1109 which gave high quantities of pectinase activity, by submerged fermentation. Different parameters such as incubation time, pH (3.5-7), temperature (20-45°C), nitrogen and carbon source, were optimized. The optimal incubation time, temperature and pH for pectinase … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 22 Jun 2015 · 7,818 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhysiological and Biochemical Evaluation of Fe-Efficiency in Fe-Deficient Maize GenotypesEntesar M. Essa, Sahar M. Zaghloul, Z.A. Salama et al.Iron (Fe) deficiency is prevalent particularly in calcareous soils of arid and semiarid regions. The present study aimed to investigate the response of eight local maize genotypes to Fe deficiency. In addition, a Fe- efficient (WF9) and a Fe-inefficient (ys1) indicator genotypes were used in this study. All genotypes were grown in growth chamber for 21 days in two levels … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 1 · 22 Apr 2015 · 7,283 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPOTENCY OF HONEY AS ANTIBACTERIAL AGENT AGAINST MULTIPLE ANTIBIOTIC RESISTANT PATHOGENS EVALUATED BY DIFFERENT METHODSMohamed Mustafa Aween, Zaiton Hassan, Nur Huda-Faujani et al.Honey is rich with complex natural components which could be useful as antibacterial agents or as preservative. Honey contains high concentration of sugars, low amount of water, high osmolality and often dark colour which influence its antibacterial activity. Disc diffusion, well method, micro dilution assay are methods commonly used to determine the antibacterial activity of honey. In this study, microtiter … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,570 accessesView PDF Cite
