stellar phoenix dbf recovery 2.0 crack In a paper entitled “Programmable and printable Bacillus subtiliscrack isale,” a team of researchers discusses how they used 3D printing to produce custom nanoscale biomaterials from the natural secretion of amyloid fibers from the bacteria Bacillus subtilis. The bacteria generate biofilms by secreting amyloid fibers via a tightly controlled cluster of genes called the tapA-sipW-tasA operon. TapA nucleates the extracellular assembly of TasA proteins to create the amyloid nanofibers that give the biofilm its structural integrity. The researchers were able to genetically modify the TasA protein and introduce functional chemical groups onto the TasA fibers excreted by the bacteria. This means that the bacterial films could be designed to act as functional living materials.

They also combined the biofilms produced with multiple bacterial strains, which allowed them to perform a two-step degradation of the pesticide paraoxan. This shows the potential for producing efficient, eco-friendly materials.

Because of the viscoelastic properties of the biofilms, they are well-suited to 3D printing. Modifying the functional groups on the secreted enzymes did not hinder the processability of the biofilms, instead enabling the researchers to tune their viscoelastic properties for 3D printing applications.

“In a series of increasingly complex proof-of-concept demonstrations, we deployed these engineered biofilms in fluorescence  detection, conjugation chemistry, single-substrate bioremediation, and multireaction bioremediation cascades incorporating NPs,” the researchers state. 
“We also exploited the intrinsic viscoelastic properties of our engineered biofilms and fabricated well-defined ‘living shapes’, trappinthese materials into hydrogels and microgels using 3D printing and microencapsulation techniques.”

The bacteria were able to incorporate onto their fibers without affecting the biofilm growth or cell viability. The cells remained viable for five weeks without supplemental nutrition.
