Microbial Development In Distillers Wet Grains Produced During Fuel Ethanol Production From Corn (Zea Mays), R. Michael Lehman, Kurt A. Rosentrater

Kurt A. Rosentrater

Distillers grains are coproduced with ethanol and carbon dioxide during the production of fuel ethanol from the dry milling and fermentation of corn grain, yet there is little basic microbiological information on these materials. We undertook a replicated field study of the microbiology of distillers wet grains (DWG) over a 9 day period following their production at an industrial fuel ethanol plant. Freshly produced DWG had a pH of about 4.4, a moisture content of about 53.5% (wet mass basis), and 4 x 10(5) total yeast cells/g dry mass, of which about 0.1% were viable. Total bacterial cells were initially …

G96-1289 Diseases Of Home Garden Strawberries, John E. Watkins, David S. Wysong

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses on some of the common diseases affecting home garden strawberries in Nebraska and their control.

Strawberries are a favored fruit of home gardens. They have been adapted to a wide range of environmental conditions, but sometimes can be challenging to grow. Strawberry yields and fruit quality are influenced by interactions of environment, diseases, pests, and soil conditions.

G95-1253 Basic Principles Of Mastitis Control, Jeffrey F. Keown, Paul J. Kononoff

University of Nebraska-Lincoln Extension: Historical Materials

Mastitis in dairy cows is a frustrating, costly, and complex infection. A good, workable, effective preventive control program is presented in this NebGuide.

General Characteristics of Mastitis

Mastitis is an inflammation of the mammary gland usually caused by bacterial infection of udder tissues. Except for rare injuries, infectious bacteria or other pathogens, e.g. yeast, fungi, etc., enter the udder through the teat end. Mastitis in both clinical (obvious abnormality, visible to naked eye) and subclinical (unseen signs of abnormality, invisible to nake eye) stages is a frustrating, costly and complex disease that reduces the quality and quantity of milk.

G95-1233 Food Safety For Child Care Facilities, Julie A. Albrecht

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines proper techniques for providing safe food in child care facilities.

Children are at high risk for food-borne illnesses. Young children are particularly vulnerable to microbial food-borne diseases because of their under-developed immune systems.

In recent years, reports of food-borne illnesses have made headlines. Most of these outbreaks involved food prepared away from home. Many cases of food-borne illness go unreported because the symptoms are similar to the flu.

Foods contaminated with microorganisms are the cause of food-borne illnesses. Contaminated food does not, however, always taste bad, smell bad, or look bad. Therefore, it is almost impossible to …

Ec93-446 Food Storage, Julie A. Albrecht, Margie Lamb

University of Nebraska-Lincoln Extension: Historical Materials

Proper food storage helps maintain food quality by retaining flavor, color, texture and nutrientsk, while reducing the chance of contracting a foodborne illness. This publication discusses ways of handling food and keeping it from spoiling.

G92-1096 Understand Your Soil Test: Ph-Excess Lime-Lime Needs, K.D. Frank, Delno Knudsen

University of Nebraska-Lincoln Extension: Historical Materials

The relationships among pH, soil type, and lime requirements are explained.

Accurate soil tests can be an excellent management tool. Misuse of soil tests leads to increased production costs, yield losses, or both. The elements required by plants for proper growth have been determined by experimentation. Experience has shown that soils across Nebraska differ greatly in their capacity to supply these elements. The amount of each element supplied by a soil depends on several factors. Two important ones are: (1) the type of material from which the soil was formed, and (2) the treatment the soil has received since being …

Ec90-434 Let's Preserve: Canning Basis, Julie A. Albrecht

University of Nebraska-Lincoln Extension: Historical Materials

Canning can be a safe and economical way to preserve quality food at home. Home preserved foods can provide a variety of nutritious food for your family all year long.

How Canning Preserves Foods

The high water content of most fresh foods makes them very perishable. Foods spoil or lose their quality for several reasons:

growth of undesirable microorganisms - bacteria,molds, and yeasts

activity of food enzymes

reactions with oxygen

moisture loss

G83-678 Producing Milk With A Low Bacteria Count, Stanely E. Wallen, Don J. Kubik, Stephen L. James, Daniel J. Borer, Gerald R. Bodman, E. Denis Erickson, Duane N. Rice, Philip H. Cole, Foster G. Owen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides cleaning, sanitizing, mechanical, environmental and other procedures to follow to assure a low bacterial count in milk. Bacteria are tiny, rapidly reproducing microorganisms that are too small to be seen without a high power microscope. Their very tiny size makes it very difficult to eliminate them from dairy equipment. Because bacterial growth in milk may cause spoilage and possibly human illnesses, a low bacterial count is one of the best indicators of top quality milk. Milk will almost always be of top quality if properly harvested from healthy, clean cows with clean equipment, cooled quickly and kept …

G74-149 Bloat Prevention And Treatment, Rick Stock, Richard J. Rasby, Duane Rice

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the types of bloat which may occur in cattle and methods to prevent and treat bloat.

Bloat is a form of indigestion marked by an excessive accumulation of gas in the rumen. Immediately after cattle consume a meal, the digestive process creates gases in the rumen. Most of the gases are eliminated by eructation (belching). Gases that are trapped and not eructated may form a foam or froth in the rumen which further prevents their elimination. Froth formation can be caused by many factors resulting from interactions between the animal, rumen microorganisms, and differences in plant biochemistry.

Microorganisms And Their Effects On Crops And Soils, T. M. Mccalla, T. H. Goodding

Nebraska Agricultural Experiment Station: Historical Circulars

Many of the cropping and tillage practices that a farmer uses are effective in crop productivity because of their influence on microbial activity.

Distribution Of Microorganisms In The Soil As Affected By Plowing And Subtilling Crop Residues, Roy C. Dawson, Virginia T. Dawson, T. M. Mccalla

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The purpose of this investigation was primarily to determine what effects rate and method of application of residues have on the distribution of microorganisms within the plow-depth layer of soil.
