Special Issue Information

Dear Colleagues,

This Special Issue is the continuation of our previous special issue “New Methods in Microbial Research 3.0”.

Earth is a microbial dependent planet. However, our understanding of the microbial world is limited, and at present, there are important gaps on comprehending the actual microbial diversity, functionality, and role of microorganisms in the environment and in the wellbeing of animals and plants. Microorganisms, in addition to their reduced size, present incredible abundance, diversity, and complexity which complicates microbial research. The major advances in microbiology are generally linked to new methodologies or the application of techniques imported from other sciences. Due to the dependence on novel methods to foster our understanding of microorganisms and the microbial communities, it is critical to promote an active platform for the dissemination of novel improvements, methods, strategies, and hypothesis-driven perspectives on microorganisms and microbial communities.

This Special Issue seeks relevant contributions of novel methods, techniques, and initiatives to better understand the microbial world. Articles are expected to provide a clear description of the proposed novel methodology and complement it with results showing its relevance to the advancement of microbiology for any discipline, such as the environment, ecology, the microbiomes, biotechnology, and the clinical field, among others.

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 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. Microorganisms 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 2700 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Abstract
Fish were kept for six weeks at three different initial stocking densities and water O2 concentrations (low-LD, 8.5 kg/m3 and 95–70% O2 saturation; medium-MD, 17 kg/m3 and 55–75% O2 saturation; high-HD, 25 kg/m3 and 60–45% O2 [...] Read more.
Fish were kept for six weeks at three different initial stocking densities and water O2 concentrations (low-LD, 8.5 kg/m3 and 95–70% O2 saturation; medium-MD, 17 kg/m3 and 55–75% O2 saturation; high-HD, 25 kg/m3 and 60–45% O2 saturation), with water temperature increasing from 19 °C to 26–27 °C. The improvement in growth performance with the decrease in stocking density was related to changes in skin and intestinal mucosal microbiomes. Changes in microbiome composition were higher in skin, with an increased abundance of Alteromonas and Massilia in HD fish. However, these bacteria genera were mutually exclusive, and Alteromonas abundance was related to a reactive behavior and systemic growth regulation via the liver Gh/Igf system, while Massilia was correlated to a proactive behavior and a growth regulatory transition towards muscle rather than liver. At the intestinal level, microbial abundance showed an opposite trend for two bacteria taxa, rendering in a low abundance of Reyranella and a high abundance of Prauserella in HD fish. This trend was correlated with up-regulated host gene expression, affecting the immune response, epithelial cell turnover, and abiotic stress response. Most of the observed responses are adaptive in nature, and they would serve to infer new welfare indicators for increased stress resilience. Full article
