Technology Strategy Board (Innovate UK) & Innovation Norway – New Funding Success

Building on the previous success with the AlgiFerm project, AlgiPharma, together with leading experts in fermentation at the Centre for Process Innovation (CPI, Redcar, UK), FMC Biopolymer, and SINTEF have secured additional funding from the UK’s Technology Strategy Board (now Innovate UK) and Innovation Norway for further investigation on microbial production of AlgiPharma’s promising new alginate oligomer drug candidate, OligoG. The study will focus on developing methods for scaling-up microbial fermentation production of OligoG at CPI.

The project, ALGIPRO, is an innovative collaborative effort between Norway and the UK. It will translate over 20 years of academic research into an industrial scale production process for alginates. The Centre for Process Innovation Ltd. (UK) is leading the scale-up based on development by SINTEF (Norway). AlgiPharma AS (Norway) will use the product as the Active Pharmaceutical Ingredient in its development of medicines for cystic fibrosis, COPD and chronic wounds. FMC Biopolymer (UK, Norway) will market the product in existing and new applications within the food and pharmaceutical markets. If successful ALGIPRO  will facilitate the introduction of novel medicinal products to the market that will ease patient suffering and potentially reduce healthcare costs. In addition it will be a new tool in fighting multi-drug resistant bacteria. The project is funded through a joint UK-Norwegian initiative between the Technology Strategy Board and Innovation Norway.

AlgiPharma awarded four year grant from Norwegian Research Council

AlgiPharma has been awarded a four year grant from the Norwegian Research Council for the project “Tailored OligoG in the treatment of chronic infectious biofilms”. This study involving an international consortium will investigate microbial sources of raw material for AlgiPharma’s alginate technology and determine optimal oligomer length associated with specific known OligoG antimicrobial properties.

The influence of a novel, safe antibiofilm therapy on the mechanical properties of Pseudomonas aeruginosa and Acinetobacter baumannii biofilms in vitro was characterized. A multiscale approach employing atomic force microscopy (AFM) and rheometry was used to quantify the mechanical disruption of the biofilms by a therapeutic polymer based on a low-molecular weight alginate oligosaccharide (OligoG). AFM demonstrated structural alterations in the biofilms exposed to OligoG, with significantly lower Young’s moduli than the untreated biofilms, (149 MPa vs 242 MPa; p < 0.05), a decreased resistance to hydrodynamic shear and an increased surface irregularity (Ra) in the untreated controls (35.2 nm ± 7.6 vs 12.1 nm ± 5.4; p < 0.05). Rheology demonstrated that increasing clinically relevant concentrations of OligoG (<10%) were associated with an increasing phase angle (δ) over a wide range of frequencies (0.1-10 Hz). These results highlight the utility of these techniques for the study of three-dimensional biofilms and for quantifying novel disruption therapies in vitro.
