Tomato Seed Disinfection with Chlorine
Chlorine is a commonly used disinfectant for tomato seed contaminated with the bacterial pathogens causing canker, spot, and speck diseases. Previous research has attempted to determine chlorine effectiveness by testing for the presence of the pathogen after treatment of infected seed lots. Even with the most advanced techniques, the accuracy of these methods is questionable, and can underestim...
متن کاملSeed train optimization for suspension cell culture
Introduction The purpose of a seed train is the generation of an adequate number of cells for the inoculation of a production bioreactor. This is timeand cost-intensive: From volumes used for cell thawing or cell line maintenance the cell number has to be increased. The cells are usually run through many cultivation systems which become larger with each passage (e.g. T-flasks, roller bottles or...
متن کاملTissue disinfection for preparation of Dendrobium in vitro culture
Establishing an aseptic in vitro culture for Dendrobium, or for any plant in fact, is the most important step towards developing an effective in vitro tissue culture including micropropagation protocol. Success in initial aseptic culture will contribute to the successful production of in vitro cultures that may involve the initiation or formation of callus and/or protocorm-like bodies (PLBs), t...
متن کاملPure Culture of Pseudomonas cepacia
A pure culture of Pseudomonas cepacia, designated AC1100, that can utilize 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) as its sole source of carbon and energy was isolated. An actively growing culture of AC1100 was able to degrade more than 97% of 2,4,5-T, present at 1 mg/ml, within 6 days as determined by chloride release, gas chromatographic, and spectrophotometric analyses. The ability of AC...
متن کاملBringing Planctomycetes into pure culture
Planctomycetes have been known since the description of Planctomyces bekefii by Gimesi at the beginning of the twentieth century (1924), although the first axenic cultures were only obtained in the 1970s. Since then, 11 genera with 14 species have been validly named and five candidatus genera belonging to the anaerobic ammonium oxidation, anammox bacteria have also been discovered. However, Pla...
