Sporulation in Distilled Water
نویسندگان
چکیده
Spores are formed when vegetative cells of sporing aerobes are shaken with distilled water at 37 degrees . These spores are derived from the small number of cells which survive lysis. The sporulation process involves increase and concentration of solid material in the cell, and is achieved at the expense of the products of lysis of 80 to 90 per cent of the resuspended cells.

Non-involvement of Lysis during Sporulation of Bacillus Mycoides in Distilled Water
Washed vegetative cells of Bacillus mycoides obtained and treated under specified conditions have been found to sporulate when shaken in distilled water under specified conditions. Within limitations of the methods, a heat-resistant cell (spore) is produced for each heat-sensitive vegetative cell present initially. Several different experiments designed to detect massive lysis and cell growth d...
متن کاملSimple method of inducing sporulation by Apophysomyces elegans and Saksenaea vasiformis.
Apophysomyces elegans and Saksenaea vasiformis are notorious for their failure to sporulate on routine media. Agar blocks, permeated with the mycelia of A. elegans and S. vasiformis, were cut aseptically from 7-day-old colonies grown on Sabouraud dextrose agar and transferred to plates containing 20 ml of sterile distilled water supplemented with 0.2 ml of 10% filter-sterilized yeast extract so...
متن کاملMethod for removal of vegetative cells from Bacterial spore preparations.
One of the more difficult and important problems encountered in analytical work on bacterial spores is the removal of the nonsporulating and unlysed vegetative cells found in all cultures which have attained maximum sporulation. A number of methods reported in the literature which have given satisfactory removal of vegetative cells of a number of species gave no appreciable separation of the sp...
متن کاملBiochemical changes occurring during sporulation of Bacillus cereus. Inhibition of sporulation by alpha-picolinic acid.
The effects of nutritional and environmental conditions on sporulation and the properties of the spore have been extensively studied with the hope that these may provide a clue to the mechanism of dormancy and resistance of the bacterial endospore. However, there is no general agreement and our knowledge of these is still limited. The extensive literature dealing with the various aspects of spo...
متن کاملEffect of Sodium Bisulfite on Peroxidase Activity and Electrolyte Leakage in Maize in Relation to Sporulation of Bipolaris maydis
In this study, we sought to determine whether the increases in peroxidase activity and electrolyte leakage induced in maize (Zea mays L.) leaves by sodium bisulfite were causally related to the sodium bisulfite-induced increases in sporulation of the pathogen Bipolaris maydis race T on infected maize leaves. Pretreatment of detached leaves of maize inbred W64 A with sodium bisulfite (500 |ig/ml...
