Resuspended freeze-dried Nannochloropsis as a model laboratory system for concentrated fresh Nannochloropsis in ultrasound cell disruption experiments
No full textMicroalgae have rigid, complex cell walls hindering direct lipid extraction. Cell disruption techniques are used to rupture these cellular structures to increase lipid extraction. Researchers investigating the downstream processing of microalgae do not always have access to microalgal cultivation systems to generate large amounts of fresh microalgal biomass. Using resuspended freeze-dried microalgal biomass as a model laboratory system for concentrated fresh biomass during cell disruption experiments offers greater flexibility in experimental planning and omits investment costs of microalgal cultivation equipment. So far, it however remains unclear whether freeze-dried resuspended biomass can be used as a model laboratory system to represent concentrated fresh biomass during cell disruption and lipid extraction experiments. This paper thus evaluated the suitability of resuspended freeze-dried Nannochloropsis as a model laboratory system for concentrated fresh Nannochloropsis during cell disruption. Ultrasound assisted cell disruption was used as example cell disruption technique and lipid extraction efficiency and free fatty acid content were investigated. Tap water and 3% sodium chloride are both suitable resuspension media for the resuspension of freeze-dried Nannochloropsis. Resuspension duration should be limited (< 120 min) to prevent the formation of free fatty acids. The condition of the biomass (concentrated fresh, or resuspended freeze-dried) prior to ultrasound assisted cell disruption did not influence the resulting lipid extraction efficiency. Resuspended freeze-dried Nannochloropsis biomass in tap water or 3% sodium chloride can thus be used as a model laboratory system for fresh microalgal biomass during research on ultrasound assisted lipid extraction. The generalization of the results to other cultivation conditions, cell disruption techniques, components of interest or microalgal species should be carefully assessed.The author(s) declare that financial support was received for the research, authorship, and/or publication of this article.

No full textLipolytische stabiliteit tijdens natte bewaring van autotrofe microalgen
No full textAutotrophic microalgae are unicellular aquatic organisms that immobilize CO2 from atmosphere and produce oxygen by photosynthesis. Microalgae contain a relatively high amount of lipids and are consequently a promising alternative source of biodiesel. The lipids from several microalgae contain also nutritionally interesting omega-3 long-chain polyunsaturated fatty acids, which makes them interesting for several food and other high value applications.
The production process of microalgae consists of several steps: cultivation, harvesting, drying and further processing steps (e.g. cell disruption and extraction) depending on the specific application. During each of these steps and during (intermediate) storage, the lipids in microalgae are susceptible to lipolysis, which has detrimental effects on flavor, nutritional value and efficiency of biofuel production. Despite the importance of lipolytic stability, this topic has been subject of only a very limited amount of studies.
The aim of this project is to study the lipolytic stability of lipids in autotrophic microalgal biomass during storage of wet biomass, with a focus on different factors determining the lipolytic stability and strategies to improve it.status: Publishe
