Studies of Autolysis
In 1904 Lane-Claypon and Schryverl reported a latent period in autolysis amounting in the normal liver to about 4 hours. In the livers of fasting animals the latent period was absent or much shorter than in the well fed. If active trypsin preparations were introduced into the autolyzing liver mass, digestion began at once. These observations led the authors to the conclusion that in the living ...
متن کاملStudies on Sucrose-Induced Autolysis of Clostridial Cells Part 1. Induction of a Rapid Bacterial Autolysis by Sucrose Treatment
Growing cells of Clostridium saccharoperbutylacetonicum Nl-4 (ATCC 13564) were rapidly autolyzed in the presence of 0.3 to 0.5M sucrose. This autolysis was apparently induced by the treatment with sucrose, and termed “sucrose-induced autolysis.” The maximum effect was shown at 0.35M sucrose, exhib i t ing about 50% loss of initial turbidity of the cell suspension. The rate of lysis depended on ...
متن کاملStudies on the effect of starvation on mycobacteria.
Ten cultures of Mycobacterium tuberculosis, one of Mycobacterium kansasii (nonsignificant), and one of Mycobacterium phlei were submitted to starvation. As a result they lost first their acid fastness and then all other staining affinities but, in this chromophobic state, they survived for at least 2 years and, after that time, produced cultures of acid-fast bacilli when transferred onto nutrie...
متن کاملMicroarray studies on lager brewer's yeasts reveal cell status in the process of autolysis.
In this work, we performed DNA microarray studies on lager brewer's yeast Saccharomyces pastorianus to investigate changes in gene expression in the process of autolysis. The two strains we used were Qing2 and 5-2. Strain 5-2 is a mutant of Qing2 and autolyzes much more slowly than its parent strain. Four samples of these two strains during different autolysis stages (0% and 15%) were tested us...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
