Nitrogen Cycling and Bacterial Community

Dear Colleagues,

Nitrogen cycling defines the biogeochemical process in which nitrogen is transformed into various forms, passing from the atmosphere to the soil, to the organism, and back to the atmosphere. Nitrogen plays a vital role in balancing the ecosystem by undergoing various types of transformation. These processes encompass the nitrogen cycle, which affects various biomes with the nitrogen cycle and is the most complicated biogeochemical process.

Microorganisms play a crucial role in N-cycling and regulate the soil N available to plants. The important process of autotrophic nitrification transforms the ammonium oxidation into nitrite and is driven by the process of ammonia oxidizing bacteria and archaea. Various studies have found that microbial community abundancy in plant canopies is due to higher N-concentrations, which increases the plant letter. Moreover, changes in the microbial utilization of nitrogen can also change the bacterial community structure. 

To understand the interrelationship between bacterial community and nitrogen cycling, detailed study is needed at the bacterial species level. In addition, the keystone bacterial genus and species involved in N-cycling in soil should be identified and introduced at a holistic level.

Assessing the relationship of bacterial community composition, abundance, diversity, and dissimilarities with N-cycling using microbiome analysis through a next-generation sequencing approach could be the best possible means of study in the present context.

This Special Issue will cover broad topics that touch the areas of bacterial community composition and diversity and their roles in N-cycling in different land use types.

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 submissions that pass pre-check are 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 250 words) can be sent to the Editorial Office for assessment.

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. Nitrogen is an international peer-reviewed open access quarterly 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 1200 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.
