preferred by most microbes for the most advantageous growth‚ although some live in slightly hypotonic solutions. (Alonzo‚ 2008) Growth in NaCl Solutions Samples of S. cerevisiae and S. epidermidis were placed into sodium chloride (NaCl) solutions of 1‚ 7 and 15 percent which were supplied in the lab kit. The S. cerevisiae results are as follows. After 24 hours of observation there was a moderate amount of growth in the 1% NaCl solution which had a cloudy overall appearance and the growth appeared

Estimation of Duckweed Geometric Population Density Phosphate Depletion By Ana Rosina Alarcon University of Texas at El Paso Department of Environmental Science Instructor: Gebregiorgis Alay G. Introduction Duckweed is a small aquatic plant that is able to grow rapidly‚ making it the ideal specimen for our experiment. It is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will

life-threatening if left untreated‚ causing sepsis if left to run rampant. A yeast delineated as S. cerevisiae appeared purple in this experiment. This would lead one to believe that it is gram-positive as well. However‚ as a fungus‚ the rules do not apply‚ as its cellular structure is different and it takes up whatever color is first introduced. The only traceable source of infection linked to S. cerevisiae is via the use of S. saccromyces as a probiotic during the course of intensive antibiotic treatment

Does IBD serology change after restorative proctocolectomy? The antimicrobial antibodies seen in patients with IBD likely represent an aberrant immune response to commensal bacterial antigens. Since restorative proctocolectomy leads to anatomical changes in the gut‚ it is logical to hypothesize that it may lead to alterations in the gut microbiome resulting in changes in the antimicrobial antibodies expression. This hypothesis has been tested in a few studies. In a retrospective study of 501 patients

DOLP- Fungi General Structure and Function: For many years‚ fungi were classified into the plantae kingdom because the two kingdoms seemed to be alike; but now‚ we know that they are all too different. In fact‚ the fungi kingdom is more closely related to the animalia kingdom. Some of the only notable similarities between the fungi and plantae kingdoms are that they are both made of eukaryotic cells‚ both immobile‚ both contain cell walls (although made of different material)‚ and both evolved
