Introduction
Chiba University iGEM07 team's project is to make a Marimo-ish gathering of bacteria. Marimo is a green spherical shaped algae, which is a popular living organism in Japan as a National Treasure. When you come to Japan, you absolutely come across to Marimo in aquariums, TV programs or Mangas :)
Backgrounds
How Marimos are Made
球形の毬藻は,他の崩れた毬藻断片を核として放射状に伸びることによって出来る.よって成長後の球形毬藻は全て一様で核が存在しない.ちなみに最初の無核球形毬藻は,他の泥や砂などを核として成長し崩れた毬藻断片を核としたと考えられている.(イメージ図)

Motivations
Why Make a "Marimo Bacteria"?
大腸菌は固体上やプレート上でそれぞれバイオフィルムやコロニーを形成するなど,固体上で集合体を生じることは知られている.しかし液体中で細胞自身が集合する例は調べる限りでは見当たらない.我々は大腸菌のみで毬藻のような独立した有限の形の集合体をつくることを目指した. (イメージ図)
