An autoradiographic spore-location technique is described that allows for the first time observation of spore germination in soil at low natural population levels (103 to 104 spores/g soil). When Fusarium solani f. sp. phaseoli was used as a test fungus, percentage macroconidial germination was greatest in nonsterile soil at 3 × 103 and 3 × 104 ...

The influence of extracellular conidial matrix on germinability was investigated using a tropical isolate of Colletotrichum capsici . Decreasing spore density and the amount of accompanying matrix increased germinability of freshly gathered spores, especially those from C. capsici the inhibitory or retardatory role of the matrix should be considered

Dry-heat inactivation of Bacillus subtilis var. niger spores with special reference to spore density
Canadian Journal of Microbiology, 1976The dry-heat inactivation kinetics of Bacillus subtilis var. niger (ATCC 9372) spores has been studied in the temperature range of 120–190 °C. The spores were applied to glass plates of a standardized area (3.24 cm2).Spore preparations of five different spore densities were used (8.3 × 104, 7.4 × 105, 7.8 × 106, 6.3 × 107, and 6.6 × 108 spores per ...

Density changes of Phycomyces spores after reversible and irreversible activation
Archives of Microbiology, 1980Spores harvested by conventional methods could be cleaned up considerably using discontinuous density gradients. This method yielded a population of almost entirely viable spores. Germination of the spores resulted in density changes probably due to spore swelling. These changes could be observed as early as 15 min after activation.

Sporormiella fungal spores, a palynological means of detecting herbivore density
Palaeogeography, Palaeoclimatology, Palaeoecology, 2006Abstract During the historic period, spores of the dung fungus Sporormiella are abundant in lake and cave sediment where livestock are plentiful in the western United States. Sporormiella spores occasionally exceed 50% of the upland pollen sum in samples from corral ponds and bed-grounds, and routinely reach 4% in lake and marsh samples in pastoral ...

Settling Rates and Density of Spores of Henneguya doori (Myxosporea) in Water
The Journal of Parasitology, 1992Using Henneguya doori from Perca flavescens (yellow perch), the current study provides a method for examining settling rates, attitudes, and densities of myxosporean spores. Fresh and fixed spores settled similarly at 8.34 x 10(-6) m/sec and 8.53 x 10(-6) m/sec, respectively.

DNA Repair by Spore Photoproduct Lyase: A Density Functional Theory Study
The Journal of Physical Chemistry B, 2003Density functional theory calculations using the hybrid functional B3LYP have been performed to probe the energetics of the spore photoproduct lyase (SPL) reactions. This enzyme catalyzes the repair of a thymine dimer caused by UV irradiation of bacterial spore DNA.
