The present study was conducted to estimate the antimicrobial activity and the potential biological control of the killer toxin produced by D. hansenii DSMZ70238 against several pathogenic microorganisms. In this study, the effects of NaCl, pH, and temperature, killer toxin production, and antimicrobial activity were studied. The results showed that the optimum inhibitory effect of killer toxin...

Among genes conserved from bacteria to mammals are those involved in replicating and repairing DNA. Following the complete sequencing of four hemiascomycetous yeast species during the course of the Genolevures 2 project, we have studied the conservation of 106 genes involved in replication, repair, and recombination in Candida glabrata, Kluyveromyces lactis, Debaryomyces hansenii, and Yarrowia ...

An inquiry was made among various organs of the Public Health Service of the State of S. Paulo, Brazil, members of the Scientific Council and Editorial Board of "Hansenologia Internationalis", and Professors of Dermatology, Bacteriology, Neurology, Pathology and Preventive Medicine of Brazil, having in view the possibility of using the term Mycobacterium hansenii in that periodical, as a substi...

Purpose: The ethanol extract of the leaves of Stachys pseudopinardii R. Bhattacharjee and Hub.–Mor. (Lamiaceae) were investigated for their antimicrobial activities. Methods: The antimicrobial activity of the leaf extract of the plant was tested against Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 7064, Staphylococcus aureus ATCC 6538P, Escherichia coli ATCC 10538, Proteus vulgaris ATCC 68...

Linear DNA plasmids were found in the following yeasts: four strains of Kluyveromyces lactis, one of Debaryomyces hansenii, one of Wingea robertsiae and four of Pichia etchellsii. In each case, the plasmids were present as a pair of DNA molecules of different sizes. The plasmids of K. lactis strains were associated with a killer activity and their structure was similar to the known killer plasm...

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...

This research study tested the protective effect of prolonged exposure shrimp food supplemented with glucans from shrimp-pond related yeasts on Penaeus vannamei reared under presence white spot syndrome virus (WSSV). The extracted and purified isolated marine identified as Debaryomyces hansenii, Candida tropicalis, humilis, glabrata, Pichia kudriavzevyi, Wickerhamomyces anomalus terrestrial Sac...
