Problem
Existing cell culture media relying on fetal bovine serum face ethical concerns, contamination issues, and supply limitations, necessitating the development of serum-free alternatives that do not require additional hormones or growth factors.
Innovation Solution
A culture medium composition utilizing a Thraustochytrid family microalgal extract, rich in nutrients, is used to promote cell proliferation and survival, replacing animal serum and addressing ethical and stability issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fetal bovine serum is used in cell culture media, then cell growth and proliferation are supported, but ethical issues and contamination problems occur
Solution Approach 1:
The patent replaces expensive, ethically problematic fetal bovine serum with a cost-effective microalgal extract that can be produced through fermentation. The microalgal extract serves as a disposable, renewable alternative that eliminates ethical concerns while maintaining cell culture support functionality.
Solution Approach 2:
The patent changes the chemical composition parameters of the culture medium by substituting animal-derived serum with microalgal extract containing different nutrient profiles including proteins, amino acids, vitamins, and minerals. This parameter change achieves the same biological function without the harmful associations of FBS.
2Productivity
If fetal bovine serum is used to support cell culture, then cell proliferation is promoted, but supply limitations and stability issues occur
Solution Approach 1:
The patent implements self-service by using fermentation technology to produce microalgal biomass that automatically contains all necessary nutrients for cell culture. The microalgae self-produce proteins, amino acids, vitamins, and minerals through their metabolic processes, eliminating the need for external supplementation and ensuring stable, contamination-free supply.
Solution Approach 2:
The patent uses a composite nutritional profile from microalgal extract that combines multiple essential components (proteins, amino acids, vitamins, minerals) into a single stable formulation. This composite material provides comprehensive cell culture support while maintaining compositional stability and resistance to contamination.
3Object-affected harmful factors
If serum-free culture media are developed to replace fetal bovine serum, then ethical and contamination issues are resolved, but additional hormones or growth factors must be added
Solution Approach 1:
The patent applies universality by using microalgal extract as a multi-functional supplement that simultaneously provides proteins, amino acids, vitamins, minerals, and other growth-promoting substances. This single ingredient replaces multiple separate additions (hormones, growth factors, amino acid mixes) required in conventional serum-free media, simplifying the overall media composition.
4Reliability
If conventional FBS production methods are used, then cell culture needs are met, but cost and supply chain vulnerabilities increase
Solution Approach 1:
The patent substitutes the complex mechanical and logistical system of FBS collection, processing, and distribution with a biological production system using fermentation. Microalgae are cultured in controlled fermenters, automatically producing the necessary nutrients, thereby replacing vulnerable supply chains with a controllable, scalable manufacturing process.
