Classically, dormant endospores are defined by their resistance properties, particularly their resistance to heat. Much of the heat resistance is due to the large amount of dipicolinic acid (DPA) stored within the spore core. During spore germination, DPA is released and allows for rehydration of the otherwise-dehydrated core. In Bacillus subtilis, 7 proteins are encoded by the spoVA operon and...

The production of biomass and lovastatin by spore-initiated submerged fermentations of Aspergillus terreus ATCC 20542 was shown to depend on the age of the spores used for inoculation. Cultures started from older spores produced significantly higher titers of lovastatin. For example, the lovastatin titer increased by 52% when the spore age at inoculation rose from 9 to 16 days. The lovastatin t...

Germinating Aspergillus nidulans conidiospores switch to polarized apical growth following an initial period of isotropic expansion. At the same time, they re-enter the nuclear division cycle. The relationship between spore polarization and nuclear division was investigated by testing the effect of cell cycle inhibitors and temperature-sensitive cell cycle mutations on spore morphogenesis. On r...

Abstract Spore-forming bacteria form the most diverse and complex group of in terms their elimination from dairy chain, due to ability highly resistant spores. As ubiquitous microorganisms, spore-formers can enter product along milk-processing continuum different sources, subsequently cause spoilage various types products. The important classes spore-forming relevant industry are Bacilli Clostr...

Spore-cell differentiation in monolayers in vitro of two sporagenous mutants of Dictyostelium discoideum, HM18 and HM15, is markedly inhibited by relatively low concentrations of the exogenous lectins, Concanavalin A (ConA) and wheat germ agglutinin (WGA) and by somewhat higher concentrations of the endogenous lectin, discoidin. The selective inhibition of spore cell formation by ConA occurs to...

Microsporidia spore surface proteins are an important, under investigated aspect of spore/host cell attachment and infection. For comparison analysis of surface proteins, we required an antibody control specific for an intracellular protein. An endoplasmic reticulum-associated heat shock protein 70 family member (Hsp70; ECU02_0100; "C1") was chosen for further analysis. DNA encoding the C1 hsp7...

In order to obtain a more stable and reusable immobilized spore laccase for dye decolorization, the spores from Bacillus pumilus W3 were immobilized on diethylaminoethyl cellulose (DEAE-cellulose). Free and immobilized spore laccase retained 34.38% and 46.11% of their initial activity, respectively, after 10 days incubation at pH 9.0. Their residual activity remained at 27.36% and 31.84% after ...
