Effect of Standard Post-harvest Interventions on the Survival and Regrowth of Antibiotic-Resistant Bacteria on Fresh Produce
… to serve as a vehicle for antibiotic -resistant bacteria is poorly understood. Antibiotics and antibiotic-resistant bacteria have been shown to persist in manure of animals administered antibiotics, and in compost generated from this manure, where there is the potential for their transfer to …

Assessing microbial quality of beer heat treated by flash and tunnel pasteurization.
… are classified as beer spoilage microorganisms, aerobic bacteria and wild yeast which have different effects on the quality of beer. Beer spoilage microorganisms are responsible for the staling of beer which is also a consequence of aerobic bacteria present in the beer. Presence of wild yeast in …

Validation of a Two-Dimensional Clinostat Design to Provide Functional Weightlessness to Custom Gas Exchange Vessels
<p>Understanding the impacts of microgravity on bacteria is vital for successful long duration space missions. In this environment, bacteria have been shown to become more virulent, more resistant to antibiotics and form more biofilms. To learn more about these phenomena, many experiments must be …

Scientific Considerations of Olestra as a Fat Substitute
… Olestra can be removed from the environment by aerobic bacteria and fungi which may be isolated from activated sludge and soils.

Food safety management practices in the traditional fish processing sector in Ghana and the microbiological safety of selected processed fish products from Ghana
… detected in fried bonga and smoked fish samples. Aerobic bacteria and coliforms were present in 50% and 44.4%, of fried bonga. Only yeast and moulds were detected in kako and koobi at levels of <2 log to 4 log cfu/g in koobi and from <2 log to 5 log cfu/g in kako. High levels of between 5 log10 …

Evaluation of the Correlation Between the Oxidation Reduction Potential and Free Chlorine Residual for Different Chlorine Sources Used in Poultry Drinking Water Sanitation
… greatly reduce or eliminate the presence of all bacteria. In recent years, the oxidation-reduction potential (ORP) meter has been a tool utilized by the poultry industry to monitor chlorine efficacy in drinking water. An ORP reading of 650-750 millivolts (mV) has become the industry standard for …

Intestinal Inflammation Model Inducing Gut Leakage by Different Methods in Broiler Chickens Using FITC-d as a Marker
… systemic (serum) FITC-d levels, total numbers of aerobic bacteria in liver as an index of bacterial translocation (BT), differential white blood cell counts, and immune organs in broiler chickens. DEX-treated chickens showed a significant increase in serum FITC-d and BT, again indicating that …

A microcosm study of the biodegradability of adsorbed toluene by acclimated bacteria in soils
… to a subsurface soil when exposed to acclimated bacteria. Toluene was chosen as a representative compound because it is a major constituent of groundwater contaminated by gasoline. In addition, toluene is known to be both biodegradable and adsorbable. Sybron Biochemical, Inc. supplied the aerobic …
