In oligotrophic environments, dust and nutrient inputs via atmospheric routes are considered important sources of macro-nutrients and micro-trace metals fuelling primary and secondary production. Yet, the impact of these dust inputs on the microbial populations is not fully investigated in the Eastern Mediterranean Sea (EMS). The response of oligotrophic systems to dust inputs, whether as positive or negative feedbacks to autotrophic and heterotrophic production and thus to biogeochemical cycling, is important to examine further. Experimental studies have explored nutrient additions in various combinations to determine the limiting resource to productivity or N2 fixation. Recent experimental studies have applied dust enrichments to bottle or mesocosm incubations of seawater from different oceanic regions. This research topic presents two Eastern Mediterranean dust addition mesocosm experiments using, for the first time, real aerosol additions, pure Saharan dust and mixed aerosols (a natural mixture of desert dust and polluted European particles), as well as other EMS aerosol experimental studies. The Topic includes manuscripts introducing results on: a) the impact of Saharan dust vs mixed aerosols on the autotrophic and heterotrophic surface microbial populations in the EMS, b) the impact of single vs multi-pulses of Saharan dust introduction into the pelagic environment of the EMS and c) other experimental studies of aerosol impacts on the EMS ecosystem.

The International Complete Collection of R&D Information about Traditional Chinese Materia Medica (TCMM) and Biotechnology (BT) Enterprises is designed as an informative medicinal reference directory listing of up-to-date R&D information about TCMM, medical biotechnology, and related medical equipment companies. The focus of this valuable and practical directory is on providing a comprehensive coverage of the most recent developments in scientific research, patents and major products of about 3,000 companies from 50 countries covering the five continents: Asia, Europe, America, Africa and the Oceania. The resource material and information are relevant and compulsory to practitioners and professionals in the fields of TCMM, medical biotechnology, biochemical industry and related medical instrumentation/equipment, as well as to organizational departments of the medicinal information management, intelligence, logistics and trade. The directory also opens up and serves as an important window through which biotech professionals master product information of their counterparts across the world. The directory will benefit professionals of medical heath, TCMM, biotechnology and related fields, as well as academics and students, executives of research, information media staffs and translators.

Since the two previous rotifer symposia in Lunz and Gent were highly successful, it was considered important to continue the tradition every third year. Thus a third rotifer symposium was held in Uppsala, Sweden, Aug. 30-Sept. 4, 1982. In the beginning of 1981 the first circular was mailed to the participants of the previous symposia, who in turn were requested to suggest names of other scientists to be invited. As a result many people expressed interest, about 70 of whom finally participated in the symposium (not including temporary visitors from nearby). The participants represented 22 countries, in Europe, North America, Asia and Australia. As with the earlier symposia, some subjects were selected in advance, mainly during discussions between Henri Dumont, Birger Pejler and Peter Starkweather when they met at the SIL congress in Kyoto 1980. Some broad topics such as 'Marine rotifers' were covered for the first time, while other topics were continuations, though more specialized, of previous themes. Thus it is interesting to follow, through the three symposium volumes, recent development within the areas of feeding, popUlation dynamics and ultrastructure. Each prospective participant (with the exception of the reviewers) was invited to present one short paper (alone or with collaborators), which resulted in more than 40 such contributions. Thus, the week's schedule became very crowded, unfortunately leaving no time for more comprehensive workshops etc. However, during the evenings general discussions were held on the topics presented during the day.

To retain their usefulness, cultures that manufacture economically valuable products must be uncontaminated, viable, and genetically stable. Maintaining Cultures for Biotechnology and Industry gives practical advice necessary to preserve and maintain cells and microorganisms important to the biotechnology and pharmaceutical industries in ways that ensure they will continue to be able to synthesize those valuable metabolites. This book covers not just those strains currently being used but also those yet to be discovered and engineered.This text is essential for anyone working with cultures who wants to avoid the frustration of losing strains and needs to be able to devise and evaluate new strategies for preservation. - Written by hands-on experts in their respective fields - Contains helpful tables and protocols for preserving or maintaining cells, cultures and viruses - Discusses means to preserve cells by freezing, lyophilization, drying, cyoprotection, spore storage, continuous propagation and subculturing when absolutely necessary, and others - Gives information needed to test cultures for stable retention of important characteristics - Gives principles needed to devise and evaluate preservation strategies for newly identified and newly engineered cells and organisms - Lists culture sources for each class of organism - Includes information for characterizing and monitoring recombinant organisms, especially important because of their propensity for genetic stability - Discusses the history of the continually evolving field of culture preservation - Examines the importance of genetically stable cultures as it relates to maintaining patent positions
