Biocontrol of Brettanomyces/Dekkera bruxellensis in alcoholic fermentations using saccharomycin-overproducing Saccharomyces cerevisiae strains. Appl Microbiol Biotechnol 2019; 103:3073-3083. [PMID: 30734124 DOI: 10.1007/s00253-019-09657-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Revised: 01/18/2019] [Accepted: 01/21/2019] [Indexed: 10/27/2022]
Abstract
Microbial contamination of alcoholic fermentation processes (e.g. winemaking and fuel-ethanol production) is a serious problem for the industry since it may render the product unacceptable and/or reduce its productivity, leading to large economic losses. Brettanomyces/Dekkera bruxellensis is one of the most dangerous microbial contaminant of ethanol industrial fermentations. In the case of wine, this yeast species can produce phenolic compounds that confer off-flavours to the final product. In fuel-ethanol fermentations, D. bruxellensis is a persistent contaminant that affects ethanol yields and productivities. We recently found that Saccharomyces cerevisiae secretes a biocide, which we named saccharomycin, composed of antimicrobial peptides (AMPs) derived from the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Saccharomycin is active against several wine-related yeast species, namely D. bruxellensis. However, the levels of saccharomycin naturally secreted by S. cerevisiae during alcoholic fermentation are not sufficient to ensure the complete death of D. bruxellensis. Therefore, the aim of the present work was to construct genetically modified S. cerevisiae strains to overproduce these GAPDH-derived AMPs. The expression levels of the nucleotides sequences encoding the AMPs were evaluated in the modified S. cerevisiae strains by RT-qPCR, confirming the success of the recombinant approach. Furthermore, we confirmed by immunological tests that the modified S. cerevisiae strains secreted higher amounts of the AMPs by comparison with the non-modified strain, inducing total death of D. bruxellensis during alcoholic fermentations.

Abstract
P-113, which was originally derived from the human saliva protein histatin 5, is a histidine-rich antimicrobial peptide with the sequence AKRHHGYKRKFH. P-113 is currently undergoing phase II clinical trial as a pharmaceutical agent to fight against fungal infections in HIV patients with oral candidiasis. Previously, we developed a new procedure for the high-yield expression and purification of hG31P, an analogue and antagonist of human CXCL8. Moreover, we have successfully removed lipopolysaccharide (LPS, endotoxin) associated with hG31P in the expression with Escherichia coli. In this paper, we have used hG31P as a novel fusion protein for the expression and purification of P-113. The purity of the expressed P-113 is more than 95% and the yield is 4 mg P-113 per liter of E. coli cell culture in Luria-Bertani (LB) medium. The antimicrobial activity of the purified P-113 was tested. Furthermore, we used circular dichroism (CD) and nuclear magnetic resonance (NMR) spectroscopy to study the structural properties of P-113. Our results indicate that using hG31P as a fusion protein to obtain large quantities of P-113 is feasible and is easy to scale up for commercial production. An effective way of producing enough P-113 for future clinical studies is evident in this study.

Abstract
The antimicrobial peptide ABP-dHC-cecropin A is a small cationic peptide with potent activity against a wide range of bacterial species. Evidence of antifungal activity has also been suggested; however, testing of this peptide has been limited due to the low expression of cecropin proteins in Escherichia coli. To improve expression of this peptide in E. coli, ABP-dHC-cecropin A was cloned into a pSUMO vector and transformed into E. coli, resulting in the production of a pSUMO-ABP-dHC-cecropin A fusion protein. The soluble form of this protein was then purified by Ni-IDA chromatography, yielding a total of 496-mg protein per liter of fermentation culture. The SUMO-ABP-dHC-cecropin A fusion protein was then cleaved using a SUMO protease and re-purified by Ni-IDA chromatography, yielding a total of 158-mg recombinant ABP-dHC-cecropin A per liter of fermentation culture at a purity of ≥94%, the highest yield reported to date. Antifungal activity assays performed using this purified recombinant peptide revealed strong antifungal activity against both Candida albicans and Neurospora crassa, as well as Rhizopus, Fusarium, Alternaria, and Mucor species. Combined with previous analyses demonstrating strong antibacterial activity against a number of important bacterial pathogens, these results confirm the use of ABP-dHC-cecropin A as a broad-spectrum antimicrobial peptide, with significant therapeutic potential.

Abstract
A novel production method in Escherichia coli for an antimicrobial peptide of 21 amino acids, buforin IIb, which is a synthetic analog of buforin II, has been developed. The buforin IIb gene was cloned into the vector pET32a to construct an expression vector pET32a-buforin IIb. The fusion protein Trx-buforin IIb, purified by nickel nitrilo-triacetic acid (Ni-NTA) resin chromatography, was cleaved by hydroxylamine hydrochloride to release recombinant buforin IIb. Purification of recombinant buforin IIb was achieved by HPLC: about 3.1 mg/l active recombinant buforin IIb with purity >99% was obtained. The recombinant buforin IIb showed antimicrobial activities that were similar to the synthetic one.

Abstract
Antibacterial peptide CM4 (ABP-CM4) is a small cationic peptide with broad-spectrum activities against bacteria, fungi, and tumor cells, which may possibly be used as an antimicrobial agent. We report here the application of small ubiquitin-related modifier (SUMO) fusion technology to the expression and purification of cationic antibacterial peptide ABP-CM4. The fusion protein expressed in a soluble form was purified to a purity of 90% by Ni-IDA chromatography and 112 mg protein of interest was obtained per liter of fermentation culture. After the SUMO-CM4 fusion protein was cleaved by the SUMO protease at 30 degrees C for 1 h, the cleaved sample was re-applied to a Ni-IDA. Finally, about 24 mg recombinant CM4 was obtained from 1 l fermentation culture with no less than 96% purity and the recombinant CM4 had similar antimicrobial properties to the synthetic CM4. Thus, the SUMO-mediated peptide expression and purification system potentially could be employed for the production of recombinant cytotoxic peptides.

Abstract
Antimicrobial peptides are an essential component of innate immunity and play an important role in host defence against microbial pathogens. They have received increasing attention recently as potential novel pharmaceutical agents. To meet the requirement for necessary basic science studies and clinical trials, large quantities of these peptides are needed. In general, isolation from natural sources and chemical synthesis are not cost-effective. The relatively low cost and easy scale-up of the recombinant approach renders it the most attractive means for large-scale production of antimicrobial peptides. Among the many systems available for protein expression, Escherichia coli remains the most widely used host. Antimicrobial peptides produced in E. coli are often expressed as fusion proteins, which effectively masks these peptides' potential lethal effect towards the bacterial host and protects the peptides from proteolytic degradation. Although some carriers confer peptide solubility, others promote the formation of inclusion bodies. The present minireview considers the most commonly used carrier proteins for fusion expression of antimicrobial peptides in E. coli. The favourable properties of SUMO (small ubiquitin-related modifier) as a novel fusion partner are also discussed.

Abstract
We have produced a small antimicrobial peptide PFWRIRIRR in bacteria utilizing production in the form of insoluble fusion protein with ketosteroid isomerase. The recombinant peptide was rapidly and efficiently isolated by acidic cleavage of the fusion protein based on the acid labile Asp-Pro bond at the N-terminus of the peptide. The peptide has antibacterial activity and neutralizes macrophage activation by LPS. The selectivity of the peptide against bacteria correlates with preferential binding to acidic phospholipid vesicles. Solution structure of the peptide in SDS and DPC micelles was determined by NMR. The peptide adopts a well-defined structure, comprising a short helical segment. Cationic and hydrophobic clusters are segregated along the molecular axis of the short helix, which is positioned perpendicular to the membrane plane. The position of the helix is shifted in two micellar types and more nonpolar surface is exposed in anionic micelles. Overall structure explains the advantageous role of the N-terminal proline residue, which forms an integral part of the hydrophobic cluster.

Abstract
It has been reported that it is difficult to express cationic antibacterial peptides in engineered bacteria because such peptides are highly toxic to the host bacteria cells and sensitive to intracellular proteases. Antibacterial peptide CM4 (ABP-CM4) is a small cationic peptide with broad-spectrum activities against bacteria, fungi and tumor cells, which may possibly be used as an antimicrobial agent. Here we tried to express ABP-CM4 in Escherichia coli cells using either the GST fusion system or the intein-mediated fusion expression system. In order to investigate the possible use of these two fusion partners in cationic small peptide expression and purification, a mutant ABP-CMt, which is a highly positively charged peptide with +9 charges at neutral pH, was designed. In the present study, we have shown that both ABP-CM4 and ABP-CMt peptides can be expressed and purified by the intein-mediated expression system but not by the GST fusion expression system. Thus the intein-mediated peptide expression and purification system potentially could be employed for the production of recombinant protease-sensitive and cytotoxic peptides.

Abstract
Several fusion strategies have been developed for the expression and purification of small antimicrobial peptides (AMPs) in recombinant bacterial expression systems. However, some of these efforts have been limited by product toxicity to host cells, product proteolysis, low expression levels, poor recovery yields, and sometimes an absence of posttranslational modifications required for biological activity. For the present work, we investigated the use of the baculoviral polyhedrin (Polh) protein as a novel fusion partner for the production of a model AMP (halocidin 18-amino-acid subunit; Hal18) in Escherichia coli. The useful solubility properties of Polh as a fusion partner facilitated the expression of the Polh-Hal18 fusion protein ( approximately 33.6 kDa) by forming insoluble inclusion bodies in E. coli which could easily be purified by inclusion body isolation and affinity purification using the fused hexahistidine tag. The recombinant Hal18 AMP ( approximately 2 kDa) could then be cleaved with hydroxylamine from the fusion protein and easily recovered by simple dialysis and centrifugation. This was facilitated by the fact that Polh was soluble during the alkaline cleavage reaction but became insoluble during dialysis at a neutral pH. Reverse-phase high-performance liquid chromatography was used to further purify the separated recombinant Hal18, giving a final yield of 30% with >90% purity. Importantly, recombinant and synthetic Hal18 peptides showed nearly identical antimicrobial activities against E. coli and Staphylococcus aureus, which were used as representative gram-negative and gram-positive bacteria, respectively. These results demonstrate that baculoviral Polh can provide an efficient and facile platform for the production or functional study of target AMPs.
