Evaluation of Chemicals for Restricting Colony Spreading by a Xerophilic Mold, Eurotium amstelodami, on Dichloran-18% Glycerol Agar.
نویسندگان
چکیده
Twenty chemicals were screened for their effectiveness in restricting colony spreading by four strains of a xerophilic mold, Eurotium amstelodami, on dichloran-18% glycerol agar. Triton X-100, Triton X-301, Tergitol NP-7, and Tergitol 15-S-3 (each at 200 mug/ml) and 1,000 mug of sodium deoxycholate, 1 mug of iprodione, 0.1 mug of propiconazole, and 0.01 mug of Maxim per ml were judged to be most effective for restricting the rate of colony spreading.

Dichloran as an inhibitor of mold spreading in fungal plating media: effects on colony diameter and enumeration.
Problems associated with overgrowth by spreading molds are not addressed by currently recommended fungal enumeration media. Twenty-two fungi, including 12 mold and 3 yeast genera, were evaluated for the effects of dichloran (2,6-dichloro-4-nitroaniline), previously identified as a mold-spreading inhibitor, on colony diameter and enumeration. On malt agar or antibiotic-potato-dextrose agar (APDA...
متن کاملMycoflora of Soybeans Used for Meju Fermentation
Diverse fungi are present in Korean traditional meju and they are known to play an important role in fermented soybean products. To determine the origin of the fungi in meju, we examined the mycoflora of soybeans from 10 traditional meju factories. The samples were untreated or treated with sodium hypochlorite, and placed on malt extract agar (MEA), dichloran 18% glycerol agar (DG18), and dichl...
متن کاملMycotoxigenic Fungi and Natural Co-Occurrence of Mycotoxins in Rainbow Trout (Oncorhynchus mykiss) Feeds
Samples of rainbow trout feed were analyzed with the aim to determine the mycobiota composition and the co-occurrence of mycotoxins. A total of 28 samples of finished rainbow trout feed from hatcheries in the provinces of Río Negro and Neuquén, Argentina, were studied. Fungal counts were obtained on three culture media in the ranges of <10 to 4.2 × 10⁴ CFU/g on Dichloran Rose Bengal Chloramphen...
متن کاملIsolation and identification of Eurotium species from contaminated rice by morphology and DNA sequencing
30 milled rice samples were collected from retailers in four states of Malaysia. These samples were evaluated for Eurotium spp. contaminations by direct plating on malt extract salt agar (MESA). All Eurotium were isolated and identified based on morphology and nucleotide sequences of internal transcribed spacer 1 (ITS1) and ITS2 of the rDNA. Four Eurotium species (E. rubrum, E. amstelodami, E....
متن کاملSpecies of Drechslera producing metabolites
Fungi which grow in stored commodities are xerophilic, that is, capable of growing at reduced water activity (aw). Some xerophilic fungi either will not grow or grow only very slowly at the high aw values of media traditionally used to enumerate yeasts and moulds in foods and feedstuffs. Populations of xerophiles may therefore be underestimated or go undetected if the media and methods normally...
