Abstract
Hairy root cultures offer a sustainable alternative to field-grown plants for the production of bioactive compounds, but their translation to industrial-scale processes is limited by the challenges of high-volume cultivation and downstream processing. In the current study, a large-scale production pipeline for basil (Ocimum basilicum) hairy roots, a rich source of specialized bioactive metabolites, is described. The production of hairy root biomass was optimized by developing a robust and scalable cultivation protocol, enabling consistent and reproducible growth in bioreactor systems with working volumes of up to 1000L. The entire production pipeline from initial Petri dish cultures to industrial-scale bioreactors was established by adopting a systematic, stepwise methodology, ensuring process reliability and scalability. A customized bioreactor with controlled aeration maintained biomass integrity and metabolic stability during long-term axenic cultivation, yielding 96.4kg of biomass fresh weight within 84 days. Complementary solvent-based extraction and pulsed electric field processing allowed the recovery of metabolites with a broad range of polarities. Untargeted metabolomics revealed a chemically diverse profile comprising primary metabolites, phenolic acids, flavonoids, terpenoids and triterpenoids with relevance for cosmetic applications. These results demonstrate the feasibility of industrial-scale basil hairy root cultures and support their use as a source of plant-derived cosmetic ingredients.
Background
The study addresses the challenge of producing bioactive compounds sustainably through hairy root cultures, which are considered an alternative to traditional field cultivation. Previous research has indicated the potential of hairy roots for metabolite production, but scaling this process for industrial use has been limited. This study is significant as it presents a systematic approach to large-scale cultivation and processing of basil hairy roots, which could have implications for the cosmetic industry.
Methods
The study employed a systematic, stepwise methodology to establish a production pipeline from Petri dish cultures to industrial-scale bioreactors. The population involved basil (Ocimum basilicum) hairy roots, with a focus on optimizing biomass yield in a customized bioreactor with controlled aeration. The primary outcome measure was the fresh weight of biomass produced over a duration of 84 days.
Results
The primary endpoint reported was a yield of 96.4 kg of biomass fresh weight within 84 days. The study also detailed the use of complementary solvent-based extraction and pulsed electric field processing for metabolite recovery, although specific yields or concentrations of metabolites were not provided.
Interpretation
The findings indicate that industrial-scale production of basil hairy roots is feasible, aligning with previous literature on the potential of hairy roots for bioactive compound production. However, the clinical significance of the metabolites for cosmetic applications remains unclear without specific efficacy data. Limitations include the lack of detailed metabolite analysis and potential confounding factors related to the scalability of the process.
