The morphology of the photosynthetic bacterium Rhodopseudomonas acidophila strain P18aF1 1.2 has been investigated with the electron microscope. The cells grow by budding, the sessile buds eventually separating from the mother cells by constriction.

The sequential morphological events in spore formation by Clostridium perfringens type D were observed in Ellner's medium where 80 to 100% of the cells formed spores. Gross structural changes were studied with the light microscope under phase-contras

This paper describes the changes in nuclear complement, cytoplasm, and cell wall which take place when short rods of Proteus mirabilis differentiate into long swarmers. In the swarmers themselves, definite cellular units are mapped out at intervals o

The process of spore germination in Clostridium pectinovorum has been followed by phase-contrast and electron microscopy. Unlike most other Bacillaceae , germination of this species takes place within the sporangium. Under phase-contrast, the spore d

Years ago (16, 18, 19), in a study of shadowed preparations of Proteus vulgaris that had been autolyzed in the cold, the observation was made that the flagella arose from basal bodies. However, recently (3, 7, 24, 33) doubt has been cast on the concl

The process by which dormant spores of Clostridium sporogenes are transformed into vegetative cells has been studied in thin sections with the electron microscope. The resting spore appears very similar to that of other Bacillaceae for it possesses a

SUMMARY: The sequence of flagellar development accompanying differentiation during multiplication in a plate culture of Proteus mirabilis was investigated with the electron microscope and the negative-staining technique; the sequence of development c

Sphaerotilus natans developed sheathed filaments in stationary liquid cultures and motile swarm cells in shaken ones. Electron microscopy of negatively stained preparations and thin sections showed that the sheath consists of fibrils. When the filame

The rate of cellulose breakdown and density of bacterial populations were measured in the epilimnetic sediments and water columns of lakes in central Ontario that differ in pH, alkalinity, and nutrient status and are particularly sensitive to acidic
