Viewed by Freeze-Etching'
The indigenous microflora of soil were released from the soil materials and concentrated without the occurrence of growth by use of a blending-simple centrifugation procedure. The cell concentrate was then frozen-etched and viewed by transmission electron microscopy. Criteria were established for detecting microbial cells among the residual soil debris. The freeze-etching of the soil cell conce...
متن کاملKnowledge as Viewed by Muslim
There are three views among Muslim thinkers concerning the nature of knowledge. Fakhr al-Din Razi holds that knowledge is self- evident and notdefinable, while Juwaini and his pupil Ghazzali hold that the concept of knowledge is theoretical and its definition is also too hard. There is another approach by the majority of Muslim theologians and philosophers who maintain that the concept of kn...
متن کاملPreservation of the Ultrastructure of Bacillus Subtilis by Chemical Fixation as Verified by Freeze-etching
The present study on the ultrastructure of Bacillus subtilis was undertaken in order to examine by means of the freeze-etching technique possible structural changes occurring during the chemical fixation procedure (Ryter-Kellenberger (R-K) fixation). Three stages were followed by freeze-etching, viz.: (a) fixation in osmium tetroxide, (b) fixation in osmium tetroxide and posttreatment with uran...
متن کاملMembrane Splitting in Freeze-etching
The freeze-etch technique was used to observe red blood cell ghosts labeled on both surfaces with covalently bound ferritin. Ferritin molecules were never observed on fracture faces, thus indicating that fracture does not show membrane-surface detail. Subliming away the surrounding ice did expose the ferritin on the membrane surface. These results were consistent with the concept that membranes...
متن کاملRotary replication for freeze-etching
Rotary replication has been adapted to freeze-etching and evaluated using T4 polyheads, erythrocyte ghosts, and chloroplast membranes. Conventional electron microscopy, electron diffraction, and optical diffraction and filtering indicate that platinum-carbon rotary replication renders radially symmetrical contrast and 25 A resolution to freeze-etched specimens so as to clarify subunit structure...
