The fungal microbiota of bloomy-rind cheeses, such as Camembert, forms a complex ecosystem that has not been well studied, and its monitoring during the ripening period remains a challenge. One limitation of enumerating yeasts and molds on traditional agar media is that hyphae are multicellular structures, and colonies on a petri dish rarely develop from single cells. In addition, fungi tend to...

A study was undertaken to find out the incidence of fungal mastitis in cattle. Out of 200 clinical cases of mastitis, 17 (8.5 %) were found to have been caused by fungi and 9 (4.5%) were identified to be mixed infection of fungi and bacteria. The yeast and yeast like fungi isolated were Candida tropicalis, Candida parapsilosis, Candida guillermondii, Geotrichum candidum, Trichosporon cutaneum, ...

The in vitro antibacterial and antifungal activities of demethoxyviridin and some synthetic analogues were evaluated by the agar diffusion method. The minimum inhibitory concentrations (MIC) of the active compounds were also determined by the agar dilution method. Demethoxyviridin (1) showed moderate antibacterial activity against most of the strains tested. 1alpha-Hydroxydemethoxyviridin (3) s...

We studied the specificity of the PLATELIA CANDIDA Ag enzyme immunoassay by using 130 isolates of 63 clinically relevant fungal species. Antigen extracts of seven Candida spp. (Candida albicans, C. dubliniensis, C. famata, C. glabrata, C. guilliermondii, C. lusitaniae, and C. tropicalis) repeatedly yielded positive reactions (>0.5 ng/ml). Geotrichum candidum and Fusarium verticillioides were fo...

A novel Geotrichum candidum aldehyde dehydrogenase (GcALDH) effectively oxidized aldehydes to carboxylic acids under mild conditions. Nonetheless, the free form of GcALDH still had a limitation in stability and recyclability. Herein, overcome these limitations, this study achieved immobilization by organic-inorganic nanocrystal formation. The exhibited 261 ± 40 % activity comparing enzyme. It a...

The interactions that occur during the ripening of smear cheeses are not well understood. Yeast-yeast interactions and yeast-bacterium interactions were investigated within a microbial community composed of three yeasts and six bacteria found in cheese. The growth dynamics of this community was precisely described during the ripening of a model cheese, and the Lotka-Volterra model was used to e...

Stickwater, a by-product of the fish meal and oil industry, is an aqueous suspension of fish proteins, lipids, and other materials, and also contains soluble nonprotein nitrogen but not carbohydrate. It is usually partially evaporated by heat to a marketable form called "fish solubles," which is sold with an acid preservative as an animal feed supplement. However, fish solubles are only used to...
