Isolation and characterization of a thermotolerant ammonia-oxidizing bacterium Nitrosomonas sp. JPCCT2 from a thermal power station.

A thermotolerant ammonia-oxidizing bacterium strain JPCCT2 was isolated from activated sludge in a thermal power station. Cells of JPCCT2 are short non-motile rods or ellipsoidal. Molecular phylogenetic analysis of 16S rRNA gene sequences demonstrated that JPCCT2 belongs to the genus Nitrosomonas with the highest similarity to Nitrosomonas nitrosa Nm90 (100%), Nitrosomonas sp. Nm148 (99.7%), and Nitrosomonas communis Nm2 (97.7%). However, G+C content of JPCCT2 DNA was 49.1 mol% and clearly different from N. nitrosa Nm90, 47.9%. JPCCT2 was capable of growing at temperatures up to 48 °C, while N. nitrosa Nm90 and N. communis Nm2 could not grow at 42°C. Moreover, JPCCT2 grew similarly at concentrations of carbonate 0 and 5 gL(-1). This is the first report that Nitrosomonas bacterium is capable of growing at temperatures higher than 37°C.

Perspectives on terminology and conceptual and professional issues in health education and health promotion credentialing.

This article was prepared to inform the deliberations of the Galway Consensus Conference by providing a common and global reference point for the discussion of terminology and key conceptual and professional issues in the credentialing of health education and health promotion specialists. The article provides a review of the terminology that is currently employed across different countries in defining health education and health promotion as well as health educator and health promotion specialist. The terminology used to describe concepts in professional credentialing of health education and health promotion specialists and the scope of professional responsibilities of such specialists, including the terms professional competencies, professional standards, and accreditation, are also reviewed. Finally, key unresolved issues are identified and discussed from a global perspective. The article concludes that despite differences in terminology in the definitions of roles and responsibilities, health education and health promotion are conceptually more similar than different across countries.

Development of certified health education specialists (CHES) in the United States: focusing on the CHES responsibilities and competencies.

Health education is an important profession. The certification of health education specialists (CHES) has evolved in the United States (U.S.) over the past 50 years. This article briefly focuses on the CHES system in the U.S. and research studies related to this topic, including coverage of the CHES responsibilities and competencies by professional school programs in the U.S., as well as other CHES issues. The CHES credentialing system in the U.S. was successfully developed over a long period of time, and its history in the U.S. is unique. Japan has now started to develop a similar certification process and is concerned about academic programs for training Japanese health educators. Awareness of the CHES system and the U.S. health education certification process and framework may help Japanese health educators and academics to tailor their health education certification processes more effectively.
