This study delineates, pelleting fodder helps meet out requirement lean consequently improving Methods: The experiment was conducted at Forage Pelleting Unit, Department Crops Agricultural College Research Inst...
By ultracentrifugation of 30 ml of highly dilute suspensions of herpes simplex virus (HSV) directly onto monolayer cultures grown in centrifuge tubes, infectivity was significantly greater than without centrifugation. Ultracentrifugation at 20,000 to 25,000 rpm (28,000 to 45,000 X g) for 1.5 to 2.3 h was utilized with good preservation of cultures. With low-speed centrifugation at 3,000 rpm (1,...
We investigated the amplification and purification of phage preparations with respect to titer, contamination level, stability, and technical affordability. Using various production systems (wave bags, stirred-tank reactors, and Erlenmeyer flasks), we obtained peak titers of 10(9) to 10(10) PFU/ml for T4-like coliphages. Phage lysates could be sterilized through 0.22-μm membrane filters without...
