The role of demand for regional development – Green transformations in the food industries in Scania and Värmland
- 2021

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Research on regional transformation typically sees regional economic change as an outcome of innovation and knowledge creation processes. The role of demand, however, has received little attention so far. In this paper, we summarize the empirical research findings from a research project on the role of demand in new regional industrial path development, focussing on the transformation of the food sector towards environmentally friendly production. The food industry is in need to renew its production system in order to cope with climate change and other environmental challenges. Further, it is a consumer-driven industry and characterized by complex and diverse demand conditions, which makes it a relevant case to study the role of demand. Theory building is based on accounts on regional industrial path development and regional innovation systems, as well as sociotechnical transitions. Empirically, we focus on two Swedish regions, Scania and Värmland, and data from a large-scale survey with all food-processing companies in the two regions as well as in-depth interviews with firm representatives and industry experts. The material is analysed in order to map and comprehend the role of altering demand conditions for regional economic transformation. We provide novel research on regional transformation of mature industries and seek to inform policies to promote industrial renewal via demand conditions.

Tidskriftsartikel (refereegranskat)abstract
- Functionally uniform monocultures have remained the paradigm in microalgal cultivation despite the apparent challenges to avoid invasions by other microorganisms. A mixed microbial consortium approach has the potential to optimize and maintain biomass production despite of seasonal changes and to be more resilient toward contaminations. Here we present a 3-year outdoor production of mixed consortia of locally adapted microalgae and bacteria in cold temperate latitude. Microalgal consortia were cultivated in flat panel photobioreactors using brackish Baltic Sea water and CO2 from a cement factory (Degerhamn, Cementa AB, Heidelberg Cement Group) as a sustainable CO2 source. To evaluate the ability of the microbial consortia to maintain stable biomass production while exposed to seasonal changes in both light and temperature, we tracked changes in the microbial community using molecular methods (16S and 18S rDNA amplicon sequencing) and monitored the biomass production and quality (lipid, protein, and carbohydrate content) over 3 years. Despite changes in environmental conditions, the mixed consortia maintained stable biomass production by alternating between two different predominant green microalgae (Monoraphidium and Mychonastes) with complementary tolerance to temperature. The bacterial population was few taxa co-occured over time and the composition did not have any connection to the shifts in microalgal taxa. We propose that a locally adapted and mixed microalgal consortia, with complementary traits, can be useful for optimizing yield of commercial scale microalgal cultivation.
