Utilization Of Peptones And Peptone Fractions By Bacteria, Margaret E. Mcmaster

Open Access Master's Theses (through 2010)

An attempt was made to determine the minimum concentration of the different peptones which are necessary to support the growth of a group of aerobic microorganisms. The medium for this experiment was semi-solid glucose peptone agar, with the peptone being varied in amount and kind.

1. The growth supporting properties of the peptones under investigation varied a great deal.
2. The minimum concentration of peptone necessary for the growth of Shigella dysenteriae, Proteus vulgaris, Streptococcus lactis, and Salmonella pullorum was determined.
3. Peptones appear to contain a substance which is toxic to Salmonella pullorum or else they lack a growth …

Cooling, Storage, And Transporation Of Milk And Cream, P. A. Downs, F. D. Yung

Nebraska Agricultural Experiment Station: Historical Circulars

The care given milk and milk products should be such that they will be relished by young and old alike. Greater use of milk can be encouraged by serving fresh milk cold. Cooling of milk also insures a fine product several hours after production. This is important not only for milk that is to be used, but for milk or cream that is to be sold.

Fermentation Of Sugar Acids By Bacteria, Gordon B. Robbins, Keith H. Lewis

Department of Chemistry: Faculty Publications

Bacterial fermentation of the sugar acids has received little attention in comparison with the wide-spread use of the common aldoses and sugar alcohols. These acids, and especially their sodium salts, are well suited to bacteriological techniques because of their solubility and heat stability, yet their usefulness for investigating the relationship of chemical structure to biological utilization has only recently been recognized. Their application to systematic differentiation of bacteria has also been neglected.

Kendall, Bly and Haner (1923) concluded from a study of three monocarboxylic acids and three dicarboxylic acids that these compounds possessed little value for the differentiation of bacterial …

Ecological Study Of The Weed Population Of Eastern Nebraska, Elva L. Norris

University Studies (University of Nebraska) (1888–1984)

EXACT knowledge of the relations existing between weeds and cultivated crops is very limited. This is true also of the amount of viable weed seed present in arable soil. Impressions and observations have been recorded, but very few quantitative investigations have been made. The numerous circulars and bulletins about weeds, issued by many experiment stations, deal mostly with descriptions of species and methods of weed control. The present research was undertaken primarily to determine the relationship which exists between weeds and cultivated crops, but also to obtain an estimation of the number of viable weed seeds present in the soil. …

Wound Healing In Potatoes (Triumph Variety) As Influenced By Type Of Injury, Nature Of Initial Exposure, And Storage Conditions, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Tubers of the Triumph variety of potatoes, the one most extensively grown in western Nebraska, are more susceptible than those of other varieties to the various types of injury that occur at harvest time. This greater susceptibility is chiefly the result of long stolons, unusual tenderness of skin, and ease with which the tubers crack. The two latter characteristics have been accentuated by the custom of late planting adopted generally throughout the region in recent years. Many of the difficulties could be avoided by growing another variety. However, as there now seems to be no other variety as well adapted …

The Chemical Nature And Distribution Of Black Pigment In Soil, William Sherman Gillam

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

As used in this paper, humus refers to that portion of the soil organic matter peptized by four per cent ammonium hydroxide. That fraction peptized by four per cent ammonium hydroxide, precipitated by acids, and insoluble in alcohol, is designated as black pigment. It is called humic soil by many writers.

Comparative Physiology Of Actinomyces In Relation To Potato Scab, Mitrofan M. Afanasiev

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present work was undertaken with the purpose of investigating the physiology of different strains of A. scabies as compared with saprophytic Actinomyces. By a comparative study of these groups, it was thought that differences in the physiology of the two might be found which would give a better understanding of the nature of this parasitism and also of the metabolism of Actinomyces in general. In addition, it was hoped that the determination of the factors influencing the parasitism of Actinomyces might establish a basis for the development of more efficient methods of controlling scab diseases. The present investigation …

Swine Erysipelas, L. Van Es, C. B. Mcgrath

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Because of the more or less frequent occurrence of swine erysipelas on Nebraska farms it seemed proper that information on this subject be made available in the form of a Station publication, especially written to serve as a reference for veterinarians, who naturally are first appealed to when an as yet relatively strange disease appears among a herd of swine. Hence the text is written in a technical form for the sake of precision. In the preparation of the text the literature of countries in which for many years the disease has constituted a permanent problem has been freely consulted. …

The Ab Urbe Condita Construction In Latin, Otto William Heick

University Studies (University of Nebraska) (1888–1984)

That type of the participial construction which has been the main object of the present investigation is known among English-speaking scholars by the name of the "ab urbe candita construction." This designation is derived from one of the outstanding examples of the type of expression in view. Ab urbe candita, "from the year of the founding of the city": thus the Romans were accustomed to reckon their chronology. The current name of this syntactical phenomenon, which is at once too vague and too narrow, might be misleading. The field of the construction is limited neither to a prepositional …

Cephalosporium Wilt And Die-Back Of The White Elm, R. W. Goss, Paul Raymond Frink

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A new disease of the white elm has been found to be common in eastern Nebraska. The causal organism has been isolated and its pathogenicity proved by inoculation. The fungus belongs to the genus Cephalosporium and is considered to be the same as that described by Curtis May of Ohio and found by him in specimens obtained in Iowa, Missouri, New York, and Washington, D.C. The morphology and cultural characters of the organism are described.

The Nature Of Resistance In Alfalfa To Wilt (Aplanobacter Insidiosum L. Mc.), George L. Peltier, F. R. Schroeder

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Alfalfa wilt was first discovered in 1924 in southern Wisconsin and northern Illinois. The causal organism, Aplanobacter insidiosum, was later described by McCulloch. Since that time wilt has been reported from most of the alfalfa-growing sections of the United States and in some states it has been responsible for a rapid decrease in the acreage of alfalfa. During the past three years a number of investigators have found that certain alfalfas are somewhat resistant to wilt, whereas others are very susceptible. At the Nebraska station the results to date indicate that all common and most variegated alfalfas are very …

The Common Intestinal Roundworm Of Swine, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Circulars

The large intestinal roundworm of pigs is a very common parasite, and is probably present in every hog raising district of Nebraska. Until the last few years the true nature of this parasite was unknown. Little did we realize the actual harm done by this worm; but through the scientific investigations of Stewart, Ransom, and others we now know that this parasite causes heavier losses to the breeder and feeder of swine than any other now common in Nebraska.

The Abortion Problem In Farm Live Stock, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

Successful animal husbandry is fundamentally dependent on the efficient reproduction and preservation of young stock. Not only are losses among the latter a prolific source of direct economic damage, but they also tend to create an equally serious disadvantage of a more indirect nature. Losses of young animals, unless a reduction of our live stock population can be tolerated, necessitate the setting aside of a larger number of females for purely reproductive purposes than would be required if such losses were not a factor.

Bovine Tuberculosis, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

The development of the present-day knowledge of the tuberculoses of animals is so intimately associated with that pertaining to the human form of the disease that the latter needs to be included in the historical considerations, without which it would be difficult to view any phase of the subject in a comprehensive manner.

The Structure And Development Of Corallobothrium With Descriptions Of Two New Fish Tapeworms (With Five Plates), Hiram Eli Essex

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Introduction

Representatives of the genus Corallobothrium from American fish have never been described. Marshall and Gilbert (1905) report two members of this genus taken from Ameiurus melas (black bullhead) caught in the lakes at Madison, Wisconsin. La Rue (1914) refers to an undescribed species of Corallobothrium encysted in the livers of A. melas and A. nebulosus (common bullhead) from the Illinois River. Ward (1918) noted the presence of a species of Corallobothrium in lctalurus punctatus (channel-cat) at Milford, Nebraska. Aside from these incidental references, the American literature contains no information on this interesting group of fish tapeworms.

Studies On The Ascaris Lumbricoides, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The Ascaris lumbricoides, in one phase or another, has attracted the attention of parasitologists for many years, and during the last decade this parasite has been studied by a large number of investigators. The recent observations have been, to a great extent, directed along one line, the study of its life history. These investigators have established two important points: (a) That the life history of Ascaris is more complex than was supposed, as it has been found that a vasculo-pulmonary circuit of the larvae is necessary before they settle down in the intestine, where they develop to the adult …
