Spores of the fungus Myrothecium verrucaria are cryptic to maltose and isomaltose. Induction of a transport system can be effected by several sugars whose order of effectiveness is: turanose > maltulose > sucrose > d-arabinose, d-fructose, nigerose, maltotriulose, kestose > melezitose, raffinose, nystose, and stachyose. The transport system is not specific to maltose and isomaltose, and it is a...

BACKGROUND Due to problems with chemical control, there is increasing interest in the use of microsporidia for control of lepidopteran pests. However, there have been few studies to evaluate the susceptibility of exotic species to microsporidia from indigenous Lepidoptera. METHODOLOGY/PRINCIPAL FINDINGS We investigated some biological characteristics of the microsporidian parasite isolated fr...

Abstract The symbiotic relationship between mycorrhizal fungi and plant roots provides benefits to the host plant. Fusarium wilt, caused by oxysporum, is most common disease on chili (Capsicum annuum), resulting in production losses of up 50%. Until now, efforts control wilt still rely chemical which has a negative impact environment.The purpose this study was examine existence number Mycorrhiz...

Bacterial spores are renowned for their longevity, ubiquity, and resistance to environmental insults, but virtually nothing is known regarding whether these metabolically dormant structures impact their surrounding chemical environments. In the present study, a number of spore-forming bacteria that produce dormant spores which enzymatically oxidize soluble Mn(II) to insoluble Mn(IV) oxides were...

background and purpose: cutaneous infections arise from a homogeneous group of keratinophilic fungi, known as dermatophytes. since these pathogenic dermatophytes are eukaryotes in nature, use of chemical antifungal agents for treatment may affect the host tissue cells. in this study, we aimed to evaluate the antifungal activity of actinomyces species against trichophyton mentagrophytes (abbrevi...

Bacterial spores are resistant to a wide range of chemical and physical insults that are normally lethal for the vegetative form of the bacterium. While the integrity of the protein coat of the spore is crucial for spore survival in vitro, far less is known about how the coat provides protection in vivo against predation by ecologically relevant hosts. In particular, assays had characterized th...

Dipicolinic acid was determined by reverse-phase liquid chromatography. Elution was with 0.2 M potassium phosphate, pH 1.8, containing 1.5% tert-amyl alcohol or higher concentrations of lower alcohols or acetonitrile. The normal analytical range was 50 to 1,000 muM, which is equivalent to 0.1 to 1 mg of spores per ml with a relative standard error of 2 to 4% and a detection limit of <100 pmol. ...

Concurrent changes in transducing efficiency and content of transforming deoxyribonucleic acid in Bacillus subtilis bacteriophage SP-10. J. Bacteriol. 91:81-88. 1966.-Spores of Bacillus subtilis W-23-S(r) infected with transducing phage SP-10 served as convenient inocula for broth cultures from which transducing phage was h...
