Our offer: Bioproduction
Experts in construction of tools for bioproduction and preparation of microbial products
Aware of the potential of using microorganisms to produce biological molecules, Smaltis has developed proprietary microbial genetic editing technology. Thanks to its genetic engineering know-how, Smaltis constructs your bioproduction tools by customizing the genome of your bacterial producers or your expression plasmids to give them new properties or optimize existing ones.
Our expertise in microbiology and molecular biology also allows us to offer a service of bioproduction of genetic material and microbial products.

Our promise: Rigor and perseverance to shape the desired tools
To meet the challenges posed by the evolving bioproduction market, a growing need for new technologies can be observed. In addition to our tools and experience, our researchers engage with expertise and perseverance to tackle these challenges with you. Simultaneously, Smaltis invests in R&D projects to build innovative bioproduction tools.
Smaltis has been able to implement tailored tools and carry out mutant construction in various species such as Escherichia coli, Pseudomonas aeruginosa, Pseudomonas fluorescens, Acinetobacter baumannii, and Klebsiella pneumoniae, using clinical isolates or reference strains available from bioresources.
From its early days, Smaltis embarked on the construction of a strain for use in bioproduction, in the Pseudomonas aeruginosa species. To achieve this, our R&D team deleted 1% of the genome of the reference strain PAO1, conferring a phenotype of antibiotic hypersensitivity and hypovirulence. This project aims to provide a new model and new technical solutions to improve the production of biologicals.

On the other hand, Smaltis researchers have also created a strain of Escherichia coli from the BL21 strain, in which the genes encoding for the DE3 phage has been deleted. This deletion provides bioproduction stakeholders with a bacterium whose protein expression is governed by the T7 promoter without the risk of releasing DE3 phages into the production environment.
Smaltis is involved in an innovative collaborative project to develop a gene delivery method for the controlled release of therapeutic proteins, with considerable medical benefits. Smaltis is enthusiastic about taking part in this project to develop an innovative, highly versatile gene transfer technology platform, which seeks to offer economic, environmental and therapeutic benefits, while improving the comfort of patients suffering from chronic diseases.
The production of biological material offered by Smaltis, whether it’s inactivated bacteria, competent strains, microbial suspensions, or genetic material preparations, systematically and rigorously involves quality controls essential for validating the produced samples. These controls are based on precise calibration, purity analysis, verification of inactivation and competence properties.

As part of the development of a simple, rapid molecular test for the detection of certain pathogenic micro-organisms in milk, we needed to work with a company with expertise in microbiology. We were looking for a qualified and experienced laboratory to prepare calibrated microbial suspensions and purified genetic material from different bacterial species. By identifying Smaltis, we were able to fully achieve our objectives thanks to the expertise of their team. We now regularly rely on this trusted partner for our recurring needs.

We use Escherichia coli strains to manufacture our Uro-Vaxom® product for the prevention of recurrent lower urinary tract infections and co-treatment of acute urinary tract infections and, in accordance with regulatory requirements, we must demonstrate the stability of our strains. We therefore asked SMALTIS to develop a tailor-made quality control method. In addition to their ability to listen to customer needs and propose new ideas, the SMALTIS team has also distinguished itself by the quality and accuracy of its analysis reports. At present, the partnership established with SMALTIS is a real asset for OM Pharma.

During our program to develop and industrialize the production of our Kinoïdes® vaccines, SMALTIS has proven to be a partner of choice for optimizing one of our cytokine production systems. Its service consisted in optimizing the genetic heritage of the host bacterium by excising DNA from exogenous sequences. Very attentive and with a rare expertise in microbiology, the SMALTIS team has always been benevolent and has never hesitated to guide us by providing sound advice. It is with pleasure that we will again call upon the services of SMALTIS to help us in our next challenges.

To test the impact of mutations identified in cancer patients, we needed to reproduce them in an expression plasmid in order to measure their effects in cell transfection models. So we turned to Smaltis and their expertise in genetic engineering. The team understood our needs perfectly, and was able to efficiently implement the directed mutagenesis strategy to obtain the desired plasmids, while guaranteeing their high quality. As a result, we were able to rapidly carry out test manipulations, which proved conclusive and enabled us to obtain the preliminary data needed to submit a major funding application. We were fully satisfied with the team's professionalism in managing this project, and with the regular and easy exchanges of information on the progress of the manipulations. We look forward to working with Smaltis again in the future.
