Special Issue Information

Dear Colleagues,

Photosynthetic production, either by plants or algae, is a sustainable method of manufacturing high-value compounds. Moreover, the use of purple phototrophic bacteria (PPB), which are also capable of utilizing light energy, is another of the most popular biorefinery methods of producing high-value proteins, biopolymers, and biofuels, as well as carotenoids, co-enzymes, and vitamins. PPB are a group of bacteria that are widely distributed in nature and live both photoheterotrophic and photoautotrophic lifestyles, consuming toxic compounds and organic matter. Thus, the application of PPB has been developed in variable fields from wastewater treatment and plant growth to single-cell protein production.

Furthermore, fundamental understanding of PPB has been extended over the years. The novel genome recovery and functional gene predictions from PPB-based biotechnologies, the investigation into the fascinating photosynthetic reaction center of PPB, and the syntrophic relationship between PPB and other microbes have frequently been the focus of recent research.

Therefore, this Special Issue aims to highlight the findings of original research articles and reviews in this field. Topics of interest for this Special Issue include but are not limited to: the understanding of production and accumulation mechanism of PPB, discovery of novel PPB, the development and optimization of PPB-related technologies, as well as current challenges and future prospects.

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. Fermentation 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 2600 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.

This review paper provides an overview of various types of photobioreactors (PBRs) that could be used for the production of polyhydroxyalkanoates (PHAs) using anoxygenic photoheterotrophs, with a focus on the design and operation of these systems. The paper highlights the potential of different PBRs based on reactor geometry and growth mode, and also examines the advantages and disadvantages of each PBR type and summarizes their suitability for PNSB-PHA production. The optimization of reactor design and operation is crucial for maximizing PNSB growth and PHA productivity. The self-immobilization of bacteria in granular sludge is a promising technology for wastewater treatment and the production of PHAs, while grooved-surface PBRs and porous-substrate PBRs have limitations due to difficult biomass harvesting in the former and the presence of aerobic conditions incongruent with PNSB culturing in the latter. Limitations exist with all solutions for maximizing rapid growth and maintaining high biomass concentrations due to the requirements of phototrophic growth. Full article
