  • incubator
  • gloves
  • autoclave bags for sterilisation
  • 500 ml glass bottle with lid

Bacteria killing:

  • Attached the step by step procedure to inoculate new plates but also growing them on textiles.
  • How to make the medium if you don't have it ready made: http://biohackacademy.github.io/bha4/cultivation-media/nutrient-agar/
  • ​​To kill the bacteria after use: * wear gloves * take all textiles out of petri dishes and place them in an autoclave bag * take all petri dishes and place them into a bag * put enough water in the pressure cooker, if you use the same pressure cooker i guess ±10 cm * close it, boil 10 min * turn it off leaving pot closed until the steam is gone * throw away autoclave bag with petri dishes * wash all the textiles with washing up liquid

learning from nature: structures (Opuntia ficus-indica - fig cactus)

Cacti are good crops for dry areas because they efficiently convert water into biomass. As Opuntia species grow in semi-arid environments, the main limiting factor in their environment is water. They have developed a number of adaptations to dry conditions, notably succulence. The perennial shrub Opuntia ficus-indica can grow up to 3-5m height, with thick, succulent and oblong to spatulate stems called cladodes. It has a water-repellent and sun-reflecting waxy epidermis and thorns for leaves.O. ficus-indica (as well as other species in Opuntia and Nopalea) is cultivated in nopalries to serve as a host plant for cochineal insects, which produce desirable red and purple dyes, a practice dating to the pre-Columbian era. DNA analysis indicated O. ficus-indica was domesticated from Opuntia species native to central Mexico. The Codex Mendoza, and other early sources, show Opuntia cladodes, as well as cochineal dye (which needs cultivated Opuntia), in Aztec tribute rolls.[citation needed] The plant spread to many parts of the Americas in pre-Columbian times, and since Columbus, have spread to many parts of the world, especially the Mediterranean, where they have become naturalized.
