Bacteria TRIZ Cases
- Recombinant Host Production of Consistent Rebaudioside D
Natural stevia extracts vary in composition and contain plant-derived contaminants; recombinant hosts use UGT enzymes to produce consistent, purer rebaudioside D.
- Modified Agrobacterium Strains for Tn904-Free Plant Transformation
Deleting functional Tn904 transposons from Agrobacterium strains limits unwanted T-DNA and chromosome insertions during plant transformation.
- Anaerobic Bacteria Preservation With Oxygen-Scavenging Lyophilization
Oxygen-scavenging agents and controlled freeze-drying help preserve anaerobic bacteria with high recovery during long-term storage.
- ARTP-Mutated Milbemycin Strain for High-Yield 3:7 A3:A4 Fermentation
An ARTP-mutated Streptomyces strain raises milbemycin fermentation yield and targets a nearly 3:7 A3:A4 ratio, reducing downstream separation and mixing steps.
- Gas-Permeable Microorganism Support Structure for Anammox Colonization
A gas-permeable layer with microorganism adhesive anchors anammox bacteria, supporting nitrogen removal with less energy and sludge.
- Sweet Sorghum Hydrogen Production Through Dark-Light Fermentation
This case combines enzyme-treated sweet sorghum with dark and light fermentation to produce and purify hydrogen at over 99% purity.
- Cell-Free Glycoprotein Synthesis with Engineered E. coli Lysates
Engineered E. coli lysates enriched with glycosyltransferases enable controllable glycosylation in cell-free therapeutic protein production.
- Polyporus Umbellatus Mycelium Growth With Raoultella FL19
Raoultella ornithinolytica FL19 promotes Polyporus umbellatus mycelium growth and supports cultivation efficiency through phosphate solubilization and auxin production.
- Frangible-Bottom Capsule Delivery Preserves Microorganism Viability
A frangible-bottom capsule and plunger release live microorganisms into liquid agricultural inputs at application, protecting viability during storage.
- Lactobacillus acidophilus GOLDGUT-LA100 BSH Screening for Cholesterol
High bile salt hydrolase activity helps GOLDGUT-LA100 lower cholesterol while surviving gastric acid in probiotic development.
- Disruptable Seed Lubricant Package for Viable Microorganism Delivery
Separate chambers keep microorganisms viable during storage, then a disruptable divider blends them with seed lubricant before planter application.
- Recombinant Shikimic Acid Strain Separating Growth From Production
Traditional fermentation can limit titer and extend production time; PopZ-regulated asymmetric division separates growth from production and reaches 88.1 g/L.
