    Phage and phage-like particles of Bacillus pumilus from an animal waste lagoon
    (North Dakota State University, 1976) Berryhill, David Lee, 1944-
    In this report (a portion of a thesis presented by K. E. Irmen in partial fulfillment of the requirements for the M.S. degree in bacteriology at North Dakota State University), we describe a new temperate bacteriophage for a Bacillus pumilus lagoon isolate. In addition, the strain lysogenic for the new phage and the B. pumilus type strain (ATCC 7061) both harbor inducible particles which resemble "killer particles" reported for other Bacillus strains (1, 12). B. pumilus ATCC 7061 also produces a second type of phage-like particle upon induction.

    Quality of livestock manure in North Dakota
    (North Dakota State University, 1987)
    Manure samples and management data were collected from 43 North Dakota cooperators and three North Dakota State University facilities. Most of the samples were collected as the manure was being pumped for land application. The samples were analyzed to determine the solids concentration, fertilizer nutrients, and other chemical components. The results were compared to published data and found to vary by as much as 100% for some nutrients. The variation appeared to relate to the housing-handling system and management programs. Manure characteristics, except potash, were not found to be closely related to rations fed to the animals.
