[PMID: 38232958 DOI: 10.1080/07388551.2023.2290981] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 03/23/2023] [Accepted: 07/27/2023] [Indexed: 01/19/2024]
Abstract
The market size of biosurfactants (BSs) has been expanding at an extremely fast pace due to their broad application scope. Therefore, the re-construction of cell factories with modified genomic and metabolic profiles for desired industrial performance has been an intriguing aspect. Typical mutagenesis approaches generate huge mutant libraries, whereas a battery of specific, robust, and cost-effective high-throughput screening (HTS) methods is requisite to screen target strains for desired phenotypes. So far, only a few specialized HTS assays have been developed for BSs that were successfully applied to obtain anticipated mutants. The most important milestones to reach, however, continue to be: specificity, sensitivity, throughput, and the potential for automation. Here, we discuss important colorimetric and fluorometric HTS approaches for possible intervention on automated HTS platforms. Moreover, we explain current bottlenecks in developing specialized HTS platforms for screening high-yielding producers and discuss possible perspectives for addressing such challenges.

Abstract
Based on the development of automatic devices and rapid assay methods, various high-throughput screening (HTS) strategies have been established for improving the performance of industrial microorganisms. We discuss the most significant factors that can improve HTS efficiency, including the construction of screening libraries with high diversity and the use of new detection methods to expand the search range and highlight target compounds. We also summarize applications of HTS for enhancing the performance of industrial microorganisms. Current challenges and potential improvements to HTS in industrial biotechnology are discussed in the context of rapid developments in synthetic biology, nanotechnology, and artificial intelligence. Rational integration will be an important driving force for constructing more efficient industrial microorganisms with wider applications in biotechnology.

Characterization of the binding of Bolton-Hunter labeled [125I]C5a to human neutrophil, monocyte and U-937 cell membranes. Mol Immunol 1992; 29:1319-24. [PMID: 1406720 DOI: 10.1016/0161-5890(92)90168-w] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/26/2022]
Abstract
The fifth component of the complement cascade, C5a, was iodinated using the Bolton-Hunter reagent. Results from the present study, using the high affinity ligand, [125I]Bolton-Hunter-labeled C5a ([125I]BH-C5a), revealed a single binding site on membranes prepared from human neutrophils, U-937 cells and human monocytes. Saturation studies demonstrated Bmax values in these cells of 11.5, 47.3 and 16.6 fmol/10(6) cells, respectively. The C5a receptor demonstrated a very high affinity for [125I]BH-C5a of approximately 4 pM in each cell type. Competition studies using analogs of C5a generated a similar order of potency in each of the cell types of C5a > or = C5a(1-74), Ser66Ala > C5a(1-73) > C5a(1-69). These studies indicate that [125I]BH-C5a labels a similar receptor in neutrophil, U-937 cell and monocyte membranes. Furthermore, C5a(1-73) produced shallow inhibition curves in competition experiments in each cell type. Computer analysis of the binding data revealed two components of binding. When 10 nM unlabeled C5a was used to initiate dissociation of [125I]BH-C5a binding in neutrophil membranes, two binding components were observed. In addition, dissociation of [125I]BH-C5a binding by 10 nM unlabeled C5a in the presence of 1 mM GppNHp decreased the percentage of binding to the slowly dissociating, high affinity binding component from 84 to 58%. These results suggest that multiple states of the C5a receptor exist.
