+Streptomyces have a life cycle similar to that of fungi. The cycle starts with growth of vegetative mycelium from a spore, followed by ariel mycelium, and, then, spores.

+Bacteria are everywhere.They create living pieces of art, e.g. the Rock Paintings : bacteria keep their colors alive.
+Pieces of art where the bacteria MAKE the piece (the design, the colors, the structure).
+This can be induced/controlled/manipulated via nutrition and monitoring of temperature/humidity conditions. Many bacteria and Lichens get their food from the air, and following they create:
+- Reflection, light dispersion
+- Luster, absorption, grating, polarisation
+- Patterns, changing colours (mix different strains of bacteria to become different colours)
+- Patterns will differ relating to different matrixes, variable growth medium
+- Chromatics, optics
+- The study of materials
+Cyanobacteria are the beginning of life. They are oxygen producing.
+Bioplastics with bacteria:
+- With seaweed /agar agar (as a substitute for gelatine)

 =====dyeing cellulose skin samples with Janthinobacterium lividum=====
 {{gallery>:bacteria:samples }}
-In the past (2017) I was succesfully growing colonies of //Lactobacillus plantarum// on cellulose skin drenched with LB medium. The biofilm with these bacteria was then used as a pollution sensor in the project Intelligent Guerilla Beehive, see the researchpage [[http://urbanbeelab.okno.be/doku.php?id=grow_your_own_beehive|grow your own beehive]]. Growing now //Janthinobacterium lividum// in the incubator, I wanted to research if this violet-blue bacteria will also thrive on microbial-skin-with-food.

 While growing the J.lividum bacteria in the petri's I found already out that they need some drops of glycerol to produce their blue color. So I made some LB growth medium with glycerol and poured it on the samples in the petris dishes, and I inoculated the 2 samples of fresh microbial skin with the J.lividum bacteria. After 2 days I saw yet a blu-ish shine on the wet white skin. I took them out of the incubator and poured some more medium. In one of the samples I injected some medium with a seringue and needle (photo 8). The next day I saw a development inside the skin-sample, but it was not clear if this was the bacteria multiplying or if it was mold. The next days it became clear that it was mold. Probably the needle was not completely sterile when I did the injection. The first sample became more and more blue, and under the microscope it was clear that the colony propagated themselves over the skin. The problem is that they constantly need food (LB) to keep them alive.

+=====alternative biohacker recipe for nutrient medium for growing bacteria=====
+__Nutrient Agar (NA)__ : Suitable for growing a wide range of bacteria none selectively
+Compound 	Amount 	Unit
+Yeast extract 	2.0 	g
+Peptone 	5.0 	g
+NaCl 	5.0 	g
+Agar 	15.0 	g
+Demi water 	up to 1000 	mL
+Set pH ~4.7
+    Please note: peptone is very dusty, so try not to inhale it.
+    Peptone can be found on eBay.
+    Yeast extract is often sold as pills in drugstores
+    Peptone can be replaced by any peptic digest of animal tissue
+    Yeast extract can be replaced by beef extract
