In a study on the possible use of plant inulin as an alternative source of fructose we have screened a large number of bacterial and yeast species for their ability to produce inulinase. Since inulinand levan-degrading capacities were often found to be present together in one species, this screening prompted a general survey of fructan-degrading abilities(More)
With different soil and water samples as inoculum and the benzimidazole fungicides benomyl (either as Benlate or as the pure compound) and thiabendazole as selective agents, a large number of, mainly fluorescent, Pseudomonas strains were isolated which nearly all were able to grow in a mineral medium with benomyl as the sole source of carbon. However, no(More)
Experiments with mixed bacterial cultures grown in liquid media which contained the benzimidazole fungicide benomyl, with or without Na-lactate, as source of carbon provided circumstantial evidence for cleavage of the benzimidazole heterocyclic ring. Yet, neither 2-aminobenzimidazole (2-AB) nor benzimidazole, as sole source of carbon, supported any(More)
Radioactivity from quinic acid-U-14C was readily incorporated into chlorogenic acid and shikimic acid in healthy andFusarium-infected tomato plants of two varieties, ‘Bonner Beste’ (susceptible) and ‘Moneymaker’ (resistant); radioactively labeled shikimic acid, on the other hand, was converted neither to quinic acid nor to chlorogenic acid. Infection led to(More)
A comparative study has been made on the effects of short-term treatment versus long-term treatment with benomyl and three thiophanates with regard to distribution of fungitoxicant (MBC, or EBC) within plants and their protection against fungal diseases. In both treatments, plants were exposed to the fungicides for two days and then transplanted to garden(More)
With respect to sensitivity to benomyl in vitro four categories of fungi were distinguished; taxonomically related fungi usually proved to belong to the same category. Within the form-class Deuteromycetes a correlation appeared to exist between sensitivity to this fungicide and morphogenesis of conidia.Phoma betae, in contrast to all otherPhoma spp., was(More)
Several strains ofAspergillus nidulans, Cladosporium cucumerinum andPenicillium italicum with known resistance to ergosterol biosynthesis inhibitors were tested for resistance to three dicarboximides. Negligible levels of resistance to iprodione and vinclozolin were observed in one out of three strains ofA. nidulans. Two out of three strains ofC.(More)
In culture filtrates ofCladosporium cucumerinum, the fungus causing cucumber scab, a constitutive, exocellular catechol oxidase was found; moreover, dihydroxy-phenylalanine and chlorogenic acid oxidases were produced. Catechol oxidase was detected in noticeable activity as soon as the pH of the culture medium had reached a value of 6.0, or if the medium was(More)
