Molecular phylogenetic position of Trichomitopsis termopsidis (Parabasalia) and evidence for the Trichomitopsiinae
The Parabasalia are one of the most morphologically diverse groups of flagellates. However, much of this diversity is restricted to organisms found only in the hindguts of wood-eating insects, primarily termites, making it difficult to acquire molecular data to study the phylogeny and evolution of diversity within this group. Here, the small subunit ribosomal RNA (SSU rRNA) has been characteris...
متن کاملSingle-Cell DNA Barcoding Using Sequences from the Small Subunit rRNA and Internal Transcribed Spacer Region Identifies New Species of Trichonympha and Trichomitopsis from the Hindgut of the Termite Zootermopsis angusticollis
To aid in their digestion of wood, lower termites are known to harbour a diverse community of prokaryotes as well as parabasalid and oxymonad protist symbionts. One of the best-studied lower termite gut communities is that of Zootermopsis angusticollis which has been known for almost 100 years to possess 3 species of Trichonympha (T. campanula, T. collaris, and T. sphaerica), 1 species of Trich...
متن کاملCellulolytic Activity of Clostridium acetobutylicum.
Clostridium acetobutylicum NRRL B527 and ATCC 824 exhibited extracellular and cell-bound endoglucanase and cellobiase activities during growth in a chemically defined medium with cellobiose as the sole source of carbohydrate. For both strains, the endoglucanase was found to be mainly extracellular (70 to 90%) during growth in continuous or batch cultures with the pH maintained at 5.2, whereas t...
متن کاملMembrane movements and fluidity during rotational motility of a termite flagellate. A freeze-fracture study
Freeze-fracture electron microscopy was used to examine the structure of a region of plasma membrane that undergoes continual, unidirectional shear. Membrane shear arises from the continual clockwise rotation of one part (head) of a termite flagellate relative to the rest of the cell. Freeze-fracture replicas show that the lipid bilayer is continuous across the shear zone. Thus, the relative mo...
متن کاملRegulation of Cellulolytic Activity in Cellulomonas Sp.iibc
METHODS The effect of glucose, cellobiose and xylose on the regulation of cellulolytic activity in Cellulomonas sp. ZZbc was investigated. The addition of 1% glucose, cellobiose or xylose to actively growing bagasse pith cultures repressed the cellulose system. No enzyme inactivation by sugar concentrations up to 1.5% was detected. Both cellobiose and xylose, at concentrations ranging from 0.00...
