Application of bioluminescent bacteria in toxicity testing of chromium The bacterial bioluminescence test (BBT) is metabolic inhibition test that uses a standardized suspension of luminescent bacteria as test organisms under standardized conditions.

Appl Environ Microbiol. 1979 Oct; 38 (4):577–584. [PMC free article] Ulitzur S, Hastings JW. Myristic acid stimulation of bacterial bioluminescence in 'aldehyde' mutants. Bioluminescence in bacteria can be regulated through a phenomenon known as autoinduction or quorum sensing. Quorom sensing is a form of cell-to-cell communication that alters gene expression in response to cell density.
The Bioluminescence Community Project meets every Monday night at 7:30 in BioCurious.
Applications of bioluminescence for environmental microbiology. Generally, the wild-type lux genes work well for Gram-negative bacteria while the fuse lux genes work best for Gram-positive bacteria. The latter is essential for luciferase expression under a single promoter in eukaryotic cells (9). Bioluminescence is the production and emission of light by a living organism. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria and terrestrial invertebrates such as fireflies.
Our Google Group is HERE.
Its efforts are divided into three tracks - Bioluminescence in the Natural World, Bioluminescence in Art, and Metabolic Engineering of Bioluminescent Genes.

OBJECTIVE: Hack a cell culture to produce bioluminescent light using luciferase
participants: anitha, cameron, jason, jessabella, kalpith, kim, matheo, michael, patrik d, patrick s, scott, steve
As a start, the pGLO infrastucture from the Green Fluorescence Protein (GFP) Experiments could be used, substituting the GFP gene with the luciferase gene, using the presence of arabinose to start gene expression and therefore luminescent activity. The 2010 E. glowli iGEM project from Cambridge produced a construct that would be an excellent starting point: http://partsregistry.org/Part:BBa_K325909
Further down the road we can think of other ways to activate the bioluminescent behaviour, add our own 'bioLOGIC'
Our weekly meeting at BioCurious is on Mondays, 7:30-10pm
Also make sure to sign up for the mailing list if you want to stay informed:
CURRENT PROJECTS:
We're exploring two different approaches right now:
can be engineered; synthetic biology project
- cannot be engineered; focus on optimizing growth conditions etc.
Things to do:
How Bioluminescence Works
- Permanent Temp sensor in Dino box
- Purchase and work with Photobacterium
- Optimize & measure Dino growth
- Grow Vibrio Fischeri on plates and in solution
- Work on Dino metabolic pathway
- LUX operon engineering
Medium Term Goals:
Glows longer
Glows brighter
Novel colors
Novel switches/promoters
Long Term Goals:
Random mutagenesis
Yeast , cyanobacteria, Other Organisms
L-Cysteine firefly luciferin recycling pathway
Needs:
Bioluminescence Where To See
Fluorescence Meter
Next Meeting will be: Download physiotherapy for respiratory and cardiac problems 4th edition free pdf.
Next Monday at 7.30pm @ Biocurious
(new people are more than welcome to join in any time)

Jul 19, 2017 Subject: Monster Girl Quest 3D [Doom Mod] Mon Jul 17, 2017 9:21 pm The creator of H-Doom is currently working on a recreation of MGQ in Doom. It's only in its early stages so there's not much in it yet, but it's moving along. Monster girl quest 3 deaths. One is Hero, an E-rated adaptation which will be altered to fit an M rating, and the other being Monster Girl Quest 3D, the unchanged adult rated version. The adult version will be a nearly exact 3D clone of the story, characters, etc. From Monster Girl Quest, though Ntelliware has hinted at. Jul 17, 2017 Re: Monster Girl Quest 3D (MGQ3D) He also has a Patreon which he created like 2 months ago. Patreon.com/hdoomguy/posts The game is completely free so you don't have. Hero is a 3D RPG for PC, Mac, and Linux based on the story and characters of an underground classic Japanese eroge/RPG called Monster Girl Quest.
The 'Terrific Science' website has some great lesson plans on DNA for High School/College level. Including:
- Characterization of the Bioluminescence (Lux +) Gene in the Microorganism E. coli Bioluminescence.pdf, which mentions E. coli strain HB101, containing the plasmid pUCD607 (see ShawNatBiotech86.pdf) with the bioluminescence (Lux +) genes
- Producing a Strain of E. coli that Glows in the DarkGlowingEcoli.pdf, using an educational kit purchased from Modern Biology, Inc.
AddGene has some plasmids with the Photorhabdus luminescens genes:

Carolina Biological Supply has the pVIb plasmid, and kits:

Bonnie Basslers TED Talk on 'The secret social lives of bacteria'
(patrick: this talk inspired and motivated me to start this project. Taking it as a fact that bacteria and cells in general do communicate with the cellular network ouround them and are 'aware' of their surroundings, the following questions and ideas arise: How can we 'communicate' with cells? What will cultures do when you give them 'lifestyle' choices?
So I am interested in creating heterogenous environments for cell cultures, instead of giving them just their desired medium and letting it sit in their desired temperature.
Ideas:
Petri dish with gradient temperature difference (controlled with open source and hardware e.g. with arduino)
Also create experiment environments where cultures can choose/ 'grow towards' different:
- Nutrients
- Toxins
- Different wavelength of light
- environments with competing culture strains
- absence of liquid / nutrients,)
So to recap: find out their 'Likes' and 'Dislikes', survival strategies, communication..

Paper on 'bacterial Bioluminescence'
If we want to extract the lux operon from Vibrio directly, and make our own plasmid from scratch, ATCC Strain Number 7744 might provide an inexpensive ($40) source of the lux genes. Need to check GenBank.
Cyanobacterial iGEM projects:
Examples
- Philips Design Microbial Home (similarly something IDEO is thinking about)
Bio-light : 'The bio-light uses different biological technologies to create ambient light effects. The concept explores the use of bioluminescent bacteria, which are fed with methane and composted material (drawn from the methane digester in the Microbial Home system). Alternatively the cellular light array can be filled with fluorescent proteins that emit different frequencies of light.'
