An improved viable counting technique was developed to facilitate study of the heat resistance of fungal spores. Spores were heated and subsequently incubated in the same medium. After germination, hyphae and germ tubes were stained with lactofuchsin, and the germinated spores were counted with the aid of a microscope. A number of xerophilic strains were examined, mostly isolates from spoiled h...

Mosquito-borne diseases are a consistent problem in Vietnam. Additionally, freshwater snail species agricultural pests and known to be intermediate hosts for several parasitic worms. There is need new complementary botanical pesticidal agents controlling these essential oils have shown promise. In this work, from 2 of Callicarpa ( C. rubella sinuata) 4 Premna P. chevalieri, corymbosa, maclurei,...

Six different species of the known teleomorphic food-borne xerophilic genus Eurotium were repeatedly isolated in a mycodiversity study of hypersaline waters. At salinities above 17% NaCl, E. amstelodami was detected most consistently, followed by E. repens and E. herbariorum, while E. rubrum, E. chevalieri and a potentially new species, "Eurotium halotolerans", were detected only occasionally a...

Indigenous agroforestry trees and shrubs on farmlands are an under-utilized resource that can be used as green manures (GM) to alleviate declining soil fertility and productivity. The aims of studies described in this thesis were to investigate: (1) the seasonal dynamics in chemical contents of foliage from selected tree species potentially available as sources of GM, (2) rates and patterns of ...

Three flavonoids were isolated for the first time from the Sudanese medicinal plants Albizia zygia. Compounds 1-3 were identified by interpretation of ESI mass data, (1)H, (13)C and 2D NMR as well as by comparison with published data as 4',7-dihydroxyflavanone (1) 3',4',7-trihydroxyflavone (2), 3-O-methylfisetin (3',4',7-trihydroxy-3-methoxyflavone, 3). All flavonoids were tested against Plasmo...

The investigation was aimed to evaluate the antifungal and antifumonisin activities of budmunchiamine A and pithecolobine against Fusarium verticillioides. The budmunchiamine A was isolated from Albizia amara and pithecolobine from Albizia saman. The results demonstrated that both budmunchiamine A and pithecolobine significantly inhibited the growth and fumonisin B1 production by F. verticillio...

Recently, the morphological and molecular features of five stain fungi infecting rubberwood (Hevea brasiliensis), namely Paecilomyces maximus, formosus, Penicillium crustosum, lecythidis Aspergillus chevalieri, have been studied. Prior to this study, authors revealed that catechin from gambir (Uncaria gambir) could inhibit growth white-rot fungus Schizophyllum commune, it was important determin...
