Based on some of your comments, and other inspirations, I posted a long page of links and excerpt/fragments covering visible bacteria sources and methods, that might be used for art or easier cheaper faster measurement of test results. Ver 2 july 12, 2016

1. so the stuff glows under the 'black light' less before oxegen in depleted, then it glows more. Other stuff might glow under the black light so they do stuff like narrow laser and LED lighting and turning it off and seeing how many milliseconds the glow stays on, and non oxygen sensitive dyes can be used as a baseline. $120 of materiels to get into the game

2. $ 350, special broth makes color changing from 'indicator' non pathenogenic ecoli, part of the poop detection industry.

2.5 ONPG broth agent 5g $87, additional broth and spliced bugs unknown.

3. Grow some marine bioluminescent bacteria. $372, hope their cousins cholera, flesh eating sepsis bacteria don’t get into the mix and into our bodies.

4. Blue is alkaline and Red is acidy using this product chemical of a bacteria, sort of a litmus test, maybe all I care about is if any color is produced equals growth.
$354 for the germ plus the broth,

5. ammonia eating bacteria for aquariums can cause white materiel, but I have not been able to get it to work sensibly.

6. Consumption of dyes by bacteria, so far have not gotten anything to work, many suggested bacteria are pathogens I don’t want to work with.

The above lays down the problem and the path to a solution which I hope to lazily accomplish with this hardware:
"Cell-in-a-Box® encapsulation differ from those produced by others. Our competitors use substances such as alginate (a seaweed derivative) or chitosan, whereas our capsules are made principally of cellulose, a bio-inert material in the human body.”

some backgrounder and nomenklatura...
n 2016, Glowee, a French company started selling bioluminescent lights, targeting shop fronts and municipal street signs as their main markets.[66] France has a law that forbids retailers and offices from illuminating their windows between 1 and 7 in the morning in order to minimize energy consumption and pollution.[67] Glowee hoped their product would get round this ban. They used bacteria called Aliivibrio fischeri which glow in the dark but the maximum lifetime of their product was three days.[66]


excerpt: "We monitor the metabolism of aerobic bacteria by using an oxygen sensitive fluorophore, ruthenium tris (2,2’-diprydl) dichloride hexahydrate (RTDP) that allows us to monitor the dissolved oxygen concentration in the nanowells. Using E.Coli K12 as a model pathogen, we demonstrate that the detection time of E.coli can be as fast as 35-60 minutes

the device with smallest sized wells (1nL volume), had the largest increase in fluorescent intensity. In comparison, the device with 100nL wells showed a slower rate of increase and those with 0.1mL wells showed only a miniscule increase over time.

(how about two pieces of glass stuck together? plain? 1 sanded? laser or water jet etched? or a clutter slurry of minscule glass beads or something)

The powder of RTDP (ruthenium tris (2,2’-dipyridyl) dichloride hexahydrate) was obtained from Sigma-Aldrich (#224758). Liquid microbial growth medium, Luria Broth (LB) purchased from Sigma-Aldrich (#L2542)."

"offline image analysis of the fluorescent intensity within the wells was calculated by using ImageJ (NIH,

E.coli strain (OP50 and K12) was used for this study. Cells were grown aerobically at 37 °C in LB medium (10 g tryptone, 10 g NaCl, 5 g Yeast extract per liter). Bacterial cells in stationary phase were harvested after overnight incubation." (K-12) $60
Ruthenium based complexes have been widely used for detection and quantification of oxygen. Fluorescence is strongly quenched by oxygen. Its benefits are:

Long lifetime and emission around 613 nm minimizing autofluorescence background

Wide range of published applications

Ru(dpp)3(PF6) proved to be very useful for use in polystyrene membranes or beads

Excellent stability and photostability

Luminescence lifetimes of several microseconds, in this general review, the outlook for measurement is looking not very plain eyeball?
oxygen insensitive reference fluorophore, Nile blue chloride (222550, Sigma Samples were excited with a 488 nm laser for Alexa Fluor 488 and Ru(Ph2phen3)Cl2 detection and with a 635 nm laser for detection of the Nile Blue chloride. OSBs incorporating an oxygen sensitive luminophore (Ru(Ph2- phen3)Cl2) and two reference fluorophores (Nile Blue chloride and Alexa Fluor 488) were produced and characterized (Fig. 1A). The OSBs showed in their fluorescence spectra peak values near 505 nm (Alexa Fluor 488) and 610 nm (ruthenium complex) for excitation with a 488 nm laser, and near 655 nm (Nile Blue) for excitation with a 635 nm laser (Fig. 1B), which indicates the incorporation of all fluorescent molecules by the bead. The selected ruthenium complex has a long unquenched lifetime after excitation [31]. Presence of molecular oxygen quenches the fluorescent signal in a diffusion-controlled manner (i.e. collisional quenching) and is described by the SterneVolmer theory [31]. Fluorescence intensity is therefore inversely proportional to the quencher concentration

B-galactosidase. I can easily make an Ecoli strain carrying the

B-galactosidase gene for you. Whether or not this would be a

sensitive enough test for cell viability, I don't know.

Photobacterium damselae: Humans can be infected with the pathogen by eating infected fish or swimming in brackish water in which the photobacterium can travel up the urinary tract of a person. Humans can experience organ failure, necrotizing fasciitis, and even death. Humans can survive between 24-72 hours with the pathogen. Antibiotics, chemotherapy, and radiation have been used to attempt to treat the infection, but have failed. The best recommendation is to amputate the infected area of the body before the pathogen spreads. [16]
For safety, teachers might use only bioluminescent species which require 30 grams of NaCl per liter of medium. Such bacteria should not be able to grow in any animal. Another safety precaution is to use bacteria which can't grow at human body temperature. Many marine and soil bacteria can't grow at such temperatures.

"The bacteria I was growing is called Streptomyces Coelicolor M145 , A(3)2. it expresses an antibiotic called actinorhodin that is blue in a basic environment and red in an acidic environment."

Bacterial bloom triggered by high levels of ammonia. Nitrifying bacteria that consume ammonia reproduce rapidly to the point that they are visible, creating what looks like clouds of swirling, white smoke. Adding too many fish at one time, overfeeding, over cleaning with chlorinated water, and the use of antibiotic medications are common triggers. If bacterial blooms occur without these triggers, it may indicate inadequate nitrifying bacteria or biological filtration.
"The ammonia uptake in NOII is ≥15 mg N-NH3/hr/kg at 25°C."

So far in my tests I got rapid creation of white particles when the "Nite out" was mixed full strength with full strength Smart n Final ammonia, I could not get residue at the very low concentrations suggested by the aquarium shop. Maybe the bacteria clumped and turned white while they were trying not to die from the ammonia concentration.

B. cereus showed maximum decolorization of 93.37% for mixed dyes under optimum conditions. This was followed by B. cytotoxicus, Bacillus sp. L10, and B. flexus showing 92.77%, 86.86%, and 85% decolorization, respectively. A study conducted by Ponraj et al.37 showed that Bacillus sp. has high decolorizing capacity for Orange 3R. They isolated Bacillus sp., Klebsiella sp., Salmonella sp., and Pseudomonas sp. from textile effluent and analyzed the decolorization of Orange 3R under optimum conditions and reported that Bacillus sp. and Pseudomonas sp.
