Molecular Determinants of Sporulation in Ashbya gossypii

Genetics, 2013
Regulation of development and entry into sporulation is critical for fungi to ensure survival of unfavorable environmental conditions. Here we present an analysis of gene sets regulating sporulation in the homothallic ascomycete Ashbya gossypii. Deletion

Sporulation of protoplasts

Folia Microbiologica, 1964
Vegetative cells ofBacillus megaterium formed protoplasts in a sucrose-stabilized medium under the influence of lysozyme. The protoplasts sporulated during subsequent incubation. The morphological properties, germination, resistance to u. v. irradiation and thermo-resistance of protoplast spores were the same as with normal cells.

Sporulation of Bacillus subtilis

Current Opinion in Microbiology, 2004
Differentiation of vegetative Bacillus subtilis into heat resistant spores is initiated by the activation of the key transcription regulator Spo0A through the phosphorelay. Subsequent events depend on the cell compartment-specific action of a series of RNA polymerase sigma factors.

Cannibalism by Sporulating Bacteria

Science, 2003
Spore formation by the bacterium Bacillus subtilis is an elaborate developmental process that is triggered by nutrient limitation. Here we report that cells that have entered the pathway to sporulate produce and export a killing factor and a signaling protein that act cooperatively to block ...

Factors Controlling the Sporulation of Yeasts II. The Sporulation Phase

Journal of Applied Bacteriology, 1967
SUMMARY The degree of sporulation exhibited by yeasts was greatly influenced by cell population density (CPD). In general, optimal sporulation occurred over a narrow range of low CPD values for solid and liquid media.

Sporulation of Mesophilic Clostridia

Journal of Applied Bacteriology, 1967
SUMMARY The commoner mesophilic clostridia have been screened for sporulation in several meat and other media. A method employing enriched spent medium has also been evaluated. A cooked meat medium based on Hartley's digest broth supported sporulation of more species than any other medium examined.

Note on study of the sporulation of fungi: endotrophic sporulation in the genusPenicillium

Folia Microbiologica, 1968
Conidiophore formation and sporulation can be induced inPenicillium sp. strain P 17 by an environmental factor—carbohydrate (carbon) starvation. Both surface and submerged mycelium, when transferred from synthetic medium to glucose-free salt solution, form conidiophores and sporulate, while in the control cultures on complete medium, vegetative growth ...

Effects of sporulation pH on the heat resistance and the sporulation of Bacillus cereus

Letters in Applied Microbiology, 1997
Spores of Bacillus cereus ATCC 7004, 4342 and 9818 were obtained in nutrient agar at several pH from 5.9 to 8.3. The optimum pH for sporulation was around 7, but good production of spores was obtained in the range 6.5-8.3. With all three strains, D-values clearly dropped with sporulation pH, decreasing by about 65% per pH unit.

THE METABOLISM OF YEAST SPORULATION: III. RESPIRATION OF SPORULATING AND GROWING CELLS

Canadian Journal of Microbiology, 1959
Cells from growth medium had a strong endogenous respiration under aerobic conditions with a respiratory quotient of approximately unity. In M/300 glucose, their oxygen uptake was somewhat greater than the endogenous, but the aerobic carbon dioxide output was approximately twice the oxygen uptake.
