The importance of selecting optimal yeast strains for research or industrial applications is often underestimated. For example, utilizing a strain background that already provides the desired stress tolerance or nutrient utilization profile can eliminate costly strain optimization. Yeast culture collections can provide not only the yeast strains but also data and curator expertise to help narrow the search for the optimal strain. While some collections are known for a broad range of cultures and services, other "boutique" collections can provide a broader selection of strains of certain categories, a surprising amount of characterization data, and assistance in selecting strains. This article provides information on dozens of yeast collections of the world, profiles of selected yeast culture collections, and the services that they provide: e.g., strain preservation for patent or safe deposit purposes, species identification service, training workshops, and consulting on yeast identification and physiology. Utilization of these services can save industrial researchers valuable time and resources. 相似文献

The Society for Melanoma Research (SMR) was created 20 years ago and has unequivocally contributed to the vast progress of the field, particularly for the treatment of melanoma patients with metastatic disease by facilitating synergistic collaborations between clinicians, researchers at the bench, and industry. In commemoration of the 20th anniversary of the first SMR International Congress (held in 2003 in Philadelphia), we look to the future by highlighting the perspectives of the next generation of rising stars, medical, and graduate students across six continents. 相似文献

Methods for the preservation of fungi in the Chytridiomycota in culture collections are reviewed in this paper. The Chytridiomycota can be preserved with varying degrees of success using a number of different protocols including cryopreservation. The survival of fungi in the Chytridiomycota is sensitive to environmental factors such as lack of moisture, high temperatures, high osmotic potential, and availability of oxygen, all of which must be considered in designing preservation methods. The age of the culture at the initiation of preservation appears to be a particularly important determinant of viability. Recently, commonly used methods for preservation of other groups of fungi have been modified to improve the survival of the Chytridiomycota in culture collections. High rates of survival have been reported after cryopreservation of aerobic and anaerobic chytrids in 10 % glycerol or dimethyl sulphoxide as cryoprotectants. The rates of freezing and thawing must be carefully controlled in the methods for cryopreservation considered in this review. Further research on increasing long-term survival rates and morphological, physiological and genetic stability of Chytridiomycota at low temperatures is necessary. 相似文献

In this brief review, literature references are given to researches--involving diverse species of protists--that support the author's firm conviction that the biological world of today absolutely requires the presence of numerous of these generally small and unicelled organisms if it is to survive. Examples supplied come from areas within the field of protistology sensu lato as widely separated as basic phycological research on photosynthesis and protozoological/medical/biomedical investigations on malaria and other pathogens of human beings. Emphasis is primarily on the most relevant works of the past 10-15 years, although historically highly significant papers of older vintage require at least indirect--and occasionally direct--citation. 相似文献

Yeast responses to stresses associated with industrial brewery handling 总被引:11,自引:0,他引:11
During brewery handling, production strains of yeast must respond to fluctuations in dissolved oxygen concentration, pH, osmolarity, ethanol concentration, nutrient supply and temperature. Fermentation performance of brewing yeast strains is dependent on their ability to adapt to these changes, particularly during batch brewery fermentation which involves the recycling (repitching) of a single yeast culture (slurry) over a number of fermentations (generations). Modern practices, such as the use of high-gravity worts and preparation of dried yeast for use as an inoculum, have increased the magnitude of the stresses to which the cell is subjected. The ability of yeast to respond effectively to these conditions is essential not only for beer production but also for maintaining the fermentation fitness of yeast for use in subsequent fermentations. During brewery handling, cells inhabit a complex environment and our understanding of stress responses under such conditions is limited. The advent of techniques capable of determining genomic and proteomic changes within the cell is likely vastly to improve our knowledge of yeast stress responses during industrial brewery handling. 相似文献

Traditional approaches for digitizing natural history collections, which include both imaging and metadata capture, are both labour- and time-intensive. Mass-digitization can only be completed if the resource-intensive steps, such as specimen selection and databasing of associated information, are minimized. Digitization of larger collections should employ an “industrial” approach, using the principles of automation and crowd sourcing, with minimal initial metadata collection including a mandatory persistent identifier. A new workflow for the mass-digitization of natural history museum collections based on these principles, and using SatScan® tray scanning system, is described. 相似文献
