The Effects Of Certain Oral Bacteria On The In Vitro Growth Of Bacteroides Gingivalis, Steven G. Morrow
The Effects Of Certain Oral Bacteria On The In Vitro Growth Of Bacteroides Gingivalis, Steven G. Morrow
Loma Linda University Electronic Theses, Dissertations & Projects
The effect of nine gram positive and grain negative cocci and bacilli, which are indigenous to the oral cavity, on the in vitro growth of Bacteroides gingivalis was examined in this study. A pure culture of B. gingivalis is was obtained from the American Type Culture Collection. The nine oral test organisms were Streptococcus mitis, Streptococcus mutans, Streptococcus faecalis, Staphylococcus epidermidis, Staphylococcus aureus, Corynebacteriurn hofmanii, Lactobacillus acidophilus, Branhamella catarrhalis, and Escherichia coli. The effect on the growth of B. gingivalis of the nine test organisms was evaluated on a solid medium by use of …
Restriction Analysis Of Bacteriophage, Ali Reza Mostaghimi
Restriction Analysis Of Bacteriophage, Ali Reza Mostaghimi
Loma Linda University Electronic Theses, Dissertations & Projects
A restriction map of DNA from bacteriophage P3-C1 for the endonucleases BamH I, Bgl II, EcoR I, Hind III, Sac I and Sca I is described in this study. The phage DNA was determined to be a linear double stranded molecule with a unit genomic length of 31 kb. After electrophoresis in 0.5% agarose gels, the undigested DNA appeared as three molecules of 31, 62 and 93 kb in length. The Hind III digestion pattern of the individual 31 kb molecule was identical to the 62 kb and 93 kb Hind III pattern. With all enzymes except Hind III, …
Comparison Of Membrane Filter, Multiple-Fermentation-Tube, And Presence-Absence Techniques For Detecting Total Coliforms In Small Community Water Systems., Nicholas J. Jacobs, Wanda L. Zeigler, Frank C. Reed, Therese A. Stukel, Eugene W. Rice
Comparison Of Membrane Filter, Multiple-Fermentation-Tube, And Presence-Absence Techniques For Detecting Total Coliforms In Small Community Water Systems., Nicholas J. Jacobs, Wanda L. Zeigler, Frank C. Reed, Therese A. Stukel, Eugene W. Rice
Dartmouth Scholarship
Methods for detecting total coliform bacteria in drinking water were compared using 1,483 different drinking water samples from 15 small community water systems in Vermont and New Hampshire. The methods included the membrane filter (MF) technique, a 10-tube fermentation tube (FT) technique, and the presence-absence (P-A) test.

CyanoNews
CyanoNews was a newsletter that served the cyanobacteriological community from 1985 to 2003, with content provided by readers (sort of a blog before there were blogs). The newsletter reported new findings from the lab, summaries of recent meetings (often provided by graduate students and post-docs entering the field), positions sought or available, life transitions, a compendium of recent cyanobacteria-related articles, and other items of interest to those who study cyanobacteria.

The Effect Of A Bacteriophage On The Competition Of Rhizobium Japonicum Strains For Nodulation Of Glycine Max (L.) Merr, Lori Kelley
Masters Theses
The symbiotic relationship between Rhizobium japonicum (Kir.) Buch. and Glycine max (L.) Merr. was the concern of this thesis. This relationship occurs naturally in soybean fields. In the field there are many different strains of Rhizobium. Some of these strains fix atmospheric nitrogen more efficiently than others resulting in a higher crop yield. The problem is the more efficient nitrogen fixers are out-competed by less efficient nitrogen fixers. In order to solve this problem the more competitive strains have to be controlled. There are two main ways to do this. One is to increase the number of the desired …
