Center for Electromicrobiology
Interesting research into electroactive bacteria, and the microstructures they build for electron transport. Lots of interesting avenues from bimimicry of the materials for new macro scale materials, to engineered geobacter for sensors

Recombinant Spidroins Fully Replicate Primary Mechanical Properties of Natural Spider Silk - Biomacromolecules (ACS Publications)
So they got bacteria to build silk proteins with are almost twice as long as real spider silk proteins, thus the doubled protein is now a near match in performance to true spider silk fiber (true spider silk fiber benefits from good protein design and spinner design though). They seem to think it should be possible to use the fusing method to build even longer proteins to up the strength.

Enzymatic construction of highly strained carbocycles | Science
Bicyclobutnae is a pain and expensive to make, so hasn't been seriously researched for rocket propellant research, but using e.coli to make it via enzyme catalyst now makes it a biofuel (biorocketfuel?). 8C boiling point versus cryogenic methane makes for an interesting trade study.

N2 gas is an effective fertilizer for bioethanol production by Zymomonas mobilis
Wow,um,so old data was wrong and new redone data says this bacteria can be fed pure nitrogen gas as fertilizer for cellulosic ethanol production, and it's awesome. Which basically means an oxygen gas separation plant's effuse of nitrogen and CO2 could be fed directly into the bacterium beds. Air Liquide must love this news...

spiber Home
Here's the swedish Spiber company. Seems like a biotech research outfit, so best guess is they are licensing core biotechnology to the japanese Spiber company, which is is by itself developing the actual textile manufacturing tech via it's linkup with a japanese auto parts maker (why not a manufacturing or textile equipment maker?)

Spiber Inc.
Japanese company commercializing mass production artificial spider silk via genetically modified microorganisms (bacteria?). The fibroin biopolymer based fiber will be called QMONOS and is scheduled for 2015 mass production at the pilot plant (100Kg/month). Except there is a swedish company with the same name, and had research in approximately the same time frame, and looking for partners. Yet this japanese company's site seems to artfully mention that this is a japanese technology push. Something smells fishy here...

Cultivation of an Obligate Fe(II)-Oxidizing Lithoautotrophic Bacterium Using Electrodes
Looks like they got rust making bacteria to live without iron, by simply supplying them electricity (electron substitute for iron oxides) and their regular diet of CO2. Which means you now have the basic foundation for a synthetic biofuel production system with electricity and CO2 inputs, provided you can tweak the bacteria to output biofuels directly like alcohols or oils, to be skimmed from a vat.
