21. Study of Candida ingens grown on the supernatant derived from the anaerobic fermentation of monogastric animal wastes.
A pellicle-forming yeast, identified as Candida ingens, was found to grow on substrates derived from the anerobic fermentation of monogastric animal wastes. The organism used volatile fatty acids C2 to C6 and ammonia nitrogen. It had a preferential uptake of the acids in increasing order of molecular weight, removing 90% of the total titratable volatile acid

22. Enhancing the Thermal Tolerance and Gastric Performance of a Microbial Phytase for Use as a Phosphate-Mobilizing Monogastric-Feed Supplement
The inclusion of phytase in monogastric animal feed has the benefit of hydrolyzing indigestible plant phytate (myo-inositol 1,2,3,4,5,6-hexakis dihydrogen phosphate) to provide poultry and swine with dietary phosphorus. An ideal phytase supplement should have a high temperature tolerance, allowing it to survive the feed pelleting process, a high specific act

23. The structure of the cells lining the stomach of the tammar wallaby (Macropus eugenii).
The stomach of the tammar may be divided into cardiac, "oesophageal", fundic and pyloric regions. In the cells of the cardiac region (which occupy 65% of the stomach) at least three types of mucous droplet are present. The stratified squamous "oesophageal" region occupies 20% of the stomach and the fundic and pyloric regions make up the remaining 15%. The ce

24. Stable accumulation of Aspergillus niger phytase in transgenic tobacco leaves.
Phytase from Aspergillus niger increases the availability of phosphorus from feed for monogastric animals by releasing phosphate from the substrate phytic acid. A phytase cDNA was constitutively expressed in transgenic tobacco (Nicotiana tabacum) plants. Secretion of the protein to the extracellular fluid was established by use of the signal sequence from th
