This study aimed to determine the antifungal activity of leaf aqueous and hydroethanolic extracts of 10 plants from the Brazilian Cerrado on Colletotrichum gloeosporioides and Corynespora cassiicola. Antifungal activity was measured through the incorporation of each extract in a culture media or spore suspension, at 50% concentration relative to the volume, determining respectively the mycelial...

Occurrence and abundance of arbuscular mycorrhizal fungi in the agricultural fields in and around Mysore district was studied. Almost all the sampling sites belong to semi-arid region. Most of the crops growing in this region were sampled. AMF percent colonization and spore density and species richness was assessed. Soil samples exhibit varied physico-chemical parameters which correlates with A...

The concentration of airborne Didymella spores has been investigated at two monitoring sites situated along the west-south transect in Poland (Szczecin, Kraków), i.e. from a height of 100 to 219 m, respectively, above sea level. The aerobiological monitoring of fungal spores was performed by means of two Lanzoni volumetric spore traps. The high Didymella spore numbers were observed at both citi...

Takahashi, I. (McMaster University, Hamilton, Ontario, Canada). Localization of spore markers on the chromosome of Bacillus subtilis. J. Bacteriol. 89:1065-1067. 1965.-Attempts were made to locate spore markers on the chromosome by determining the mapping distance of ery(r), str(r), phe, tyr, and ser markers to which the spore markers are closely linked. The results obtained indicated that locu...

Spore formers are bacteria able to survive harsh environmental conditions by differentiating a specialized, highly resistant spore. In Bacillus subtilis, the model system for spore formers, the recently discovered crust and the proteinaceous coat are the external layers that surround the spore and contribute to its survival. The coat is formed by about seventy different proteins assembled and o...

fruit leather is one of dried product with variable production, good marketing and popular consumption in many countries of the world. in this research, the effect of concentration temperature (55-75 °c) and time (20-40 min) and drying temperature (40-70 °c) on the chemical composition (brix, ph, sugars and vitamin c) and the microbial properties of apple leather investigated. the results showe...

the impact of land use intensity on the abundance and diversity of arbuscular mycorrhizal fungi (amf) was investigated at six land use types viz., natural forest, grassland, acacia plantations, cardamom plantations, coffee plantations and paddy fields in the niligiri biosphere of the western ghats in south india. there was no significant difference in amf root colonization in different land use...

american foulbrood (afb) disease is caused by the sporeforming bacterium paenibacillus larvae larvae. traditional diagnosis is based on culture technique is time and laboratory work consuming. in this study with standard strain, pcr was developed by specific primers and pcr products were electrophoresed on 0.8 % agarose gel. the pcr primers were selected on the basis of the 16s rrna gene and am...

Effects of different carbon sources on growth and production of antifungal agent(s) by Gymnopilus spectabilis were investigated. Different carbon sources including; Glucose, fructose, lactose, maltose, manitol and sucrose at the concentration of 10 g/l and slow releasing carbon sources including malt extract and soluble starch at the concentration of 2g/l were used. Inhibition of spore germinat...
