Use of a fluorescent brightener to demonstrate cellulose in the cellular slime molds.
The presence and location of cellulose in different stages of the life cycles of the cellular slime molds can be demonstrated by use of the disodium salt of 4,4'-bis(4-anilino-6-bis (2-hydroxyethyl)-amino-s-triazin-2-ylamino)-2,2' -stilbene disulfonic acid, a fluorescent brightener. It may be used successfully as a direct stain at a concentration of 0.1% in half-normal saline at pH 6; and it ma...
متن کاملDictyostelid Cellular Slime Molds from Caves
Dictyostelid cellular slime molds (dictyostelids) are singlecelled, eukaryotic, phagotrophic bacterivores usually present and often abundant in terrestrial ecosystems (Raper, 1984). These organisms represent a normal component of the microflora in soils and apparently play a role in maintaining the natural balance that exists between bacteria and other microorganisms in the soil environment. Fo...
متن کاملDo cellular slime molds form intercellular junctions?
Intercellular contact specializations such as gap junctions have been thought to play a role in growth and differentiation in many systems. This idea is based on the observation that small molecules can pass directly between the cytoplasms of adjacent cells and on the strong circumstantial evidence that gap junctions may provide for this intercellular permeability (1). Gap junctions are found i...
متن کاملDictyostelid Cellular Slime Molds from Hawai'i
Soil and litter samples, collected from Hawai'i on the islands of Hawai'i, O'ahu, and Kaua'i, were examined for occurrence and distribution of dictyostelid cellular slime molds. In total, 194 samples, from 20 different sites and representing several plant communities, were collected during June 1995 and processed in the laboratory soon thereafter. A total of 10 species and one variety was recov...
متن کاملEffect of bacteria on chemotaxis in the cellular slime molds.
The effect of chemotactic substances, secreted by Escherichia coli, on the cellular slime molds was studied by deposition of bacteria near myxamoebae populations. Droplets of a bacterial suspension and a myxamoebae suspension were placed separately, at predetermined distances from each other, on a hydrophobic agar surface of low rigidity. Myxamoebae remained confined inside the droplets, except...
