Mighty Materials



A closer look into the current biotechnological revolution that will transform the fashion industry and the impact the industry has on the environment.


Materials grown and engineered from live microorganisms are redefining materials, manufacturing, sustainability, even the design process.


Up until now, sustainable efforts have had issues closing the loop in a circular model. Most sustainable options still face numerous tradeoffs, for instance being emission intensive, environmentally degrading, using sources from mono-cropping, relying on petroleum-based sources, etc.


The combination of biology and lab processes to grow materials will fundamentally solve the problem of creating a truly circular material. Doing this by transforming organic raw materials into beautifully biofabricated textiles, nonwovens, and dyes, while maintaining durability, performance, and consumer interest.


The structure, thickness, color, and texture of the finished material can all be programmed into the DNA of the cells of the microorganisms. This can expand to create seamless forms and even embed closures. Making the possibilities limitless.

See below on products in development and some currently in the market.



[ MICROORGANISMS FROM ]


+ Fungi

+ Algae

+ Animal Cells

+ Bacteria

+ Yeast


[ ISOLATED TERMS ]


Gram-positive bacteria: bacteria resulting in positive test on the Gram stain test, used to classify bacteria into two categories based on the type of cell wall. A gram-positive bacteria has a thicker peptidoglycan layer, that retains a violet stain after washed from the sample.


Mycelium: the mass of white filaments(hyphae) branching from the vegetative part of the fungus.


Hyphae: the web filamentous structure of a fungus. Collectively called mycelium.


Actinobacteria: a phylum of gram-positive bacteria, that contributes to decomposing organic matter of dead organism so the molecules can be taken up anew.


Streptomyces: one of the largest genus of Antinobacteria. Forming a threadlike net called a mycelium, producing spores. Over 500 species have been described. Predominantly found in soil and decaying vegetation.


Ideonella sakaiensis - bacterium with the capability of breaking down and metabolizing plastic PET fiber, synthetic fiber garments. Creating a viable bioremediation strategy.


Streptomyces coelicolor: produces pink to red prodignine molecules and the soluble molecule actinorhodin.


Mycorestoration: ability of using fungi to restore ecosystems and degraded environments.


Saccharification: the process of breaking down complex carbohydrates, such as sugar cane, into monosaccharide components.


Janthinkobacterium lividum: soil dwelling bacteria, that produces shades of purple (Volacein).


Arthrobacter Agilis: a psychrotrophic bacterium, that produces shades of reds.


Micrococcus Leteus: is a gram positive saprotrophic bacterium, producing pigments of yellows.
