Special Issue Information

Dear Colleagues,

Microbes can be found in most of the built environment (BE), including our homes, public places, and inside vehicles. These microbes may form a unique community in each place and affect human health. Understanding the microbes of the indoor environment is a crucial step to take; as an example, the airborne infection may occur in the indoor environment. Recent findings have indicated that specific microbes can help to confront asthma-related problems. The roles of microbes in the built environments became a more important research topic, and it is necessitated to be disseminated from the public health aspect. It is essential to increase the knowledge of the microbe in the indoor environment with various disciplines to achieve decent indoor air quality to sustain our health. We welcome you to submit the abstract to microbes related to indoor air quality.

This Special Issue will attempt to highlight the following questions as a framework to acquire information associated with health and microbiomes in BE.

  • Where are the microbes in BE coming from? (i.e., source of the microbes in the BE);
  • How can lifestyle affect microbes in the BE? (i.e., soil and outside material to be transported by shoes, soil material attached with food (e.g., vegetable), airborne transport, aerosol from the tap water system, having companion animals, and more);
  • Which criteria affect the microbiome of the BE? (i.e., availability of foliage house plant, companion animals, and carpet, type of building, construction material used, and age of the building);
  • What is the variation of diversity level and distribution/numbers of available microbes in the BE? (i.e., diversity variation with annual and diurnal cycles and a number of occupants per household, distribution/amount difference among wall, floor, ceiling, under the floor of BE and room type as a kitchen, bathroom, bedroom, and more);
  • How is the exchange rate of occupants and the type of BE affecting the criteria mentioned above? (i.e., residential hoses and public places, inside the transportation system such as train, subway, bus, airplane, ship and more and associated movement of the microbiome).

Finally, we believe this Special Issue will provide a platform to highlight new research and significant advances in the understanding of this emerging field in microbiology.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
