Abstract

The production of single-cell protein (SCP) from microorganisms holds significant importance due to its potential as an alternative protein source. Photosynthetic bacteria (PSB) wastewater treatment and resource recovery method stands out as an effective means to produce SCP, protein content is usually in the 40-60% range, thereby making it a highly valuable byproduct. This comprehensive review not only summarizes the current methods for the production and utilization of SCP but also traces the historical evolution of protein production from PSB wastewater treatment. It delves into the various factors that influence the yield of SCP, meticulously analyzing aspects such as the specific PSB strain employed, the type of wastewater processed, and the light-oxygen conditions under which the process occurs.While this technology has garnered increasing attention in recent years owing to its dual benefits of wastewater treatment and SCP production, the number of studies conducted in this field remains relatively scarce. Furthermore, the majority of these studies have primarily focused on the utilization of the Rhodopseudomonas genus for treating food wastewater treatment under light-anaerobic conditions. Despite these advancements, challenges to economic viability and limitations to industrial-scale production remain. At the conclusion of this review, we discuss the existing problems within the technology, such as the need for optimized conditions for different PSB strains and wastewater types, as well as the potential future prospects for its widespread adoption and commercialization.

期刊介绍： Biotechnology Letters is the world’s leading rapid-publication primary journal dedicated to biotechnology as a whole – that is to topics relating to actual or potential applications of biological reactions affected by microbial, plant or animal cells and biocatalysts derived from them. All relevant aspects of molecular biology, genetics and cell biochemistry, of process and reactor design, of pre- and post-treatment steps, and of manufacturing or service operations are therefore included. Contributions from industrial and academic laboratories are equally welcome. We also welcome contributions covering biotechnological aspects of regenerative medicine and biomaterials and also cancer biotechnology. Criteria for the acceptance of papers relate to our aim of publishing useful and informative results that will be of value to other workers in related fields. The emphasis is very much on novelty and immediacy in order to justify rapid publication of authors’ results. It should be noted, however, that we do not normally publish papers (but this is not absolute) that deal with unidentified consortia of microorganisms (e.g. as in activated sludge) as these results may not be easily reproducible in other laboratories. Papers describing the isolation and identification of microorganisms are not regarded as appropriate but such information can be appended as supporting information to a paper. Papers dealing with simple process development are usually considered to lack sufficient novelty or interest to warrant publication.
