How do spores survive and germinate?

When various extreme stresses were applied to the materials, including ethanol, high osmolarity, low pH, UV light, and radiation, the spores were able to survive and quickly germinate. This work demonstrates a route by which materials can retain the functions provided by embedded living cells long after they are created.

Can bacterial spores generate electricity?

A previous study found that bacterial spores, which rapidly shrivel in dry conditions and replump with hydration, are packed with power and could be used to generate electricity. Now, in a follow-up study, researchers have built tiny spore-powered engines, which can run an LED and a miniature car weighing 0.1 kilograms.

How do spores survive a chemical reaction?

These functions include responding to chemicals detected by genetically encoded chemical sensors and sensing or killing of Staphylococcus aureus. When various extreme stresses were applied to the materials, including ethanol, high osmolarity, low pH, UV light, and radiation, the spores were able to survive and quickly germinate.

Can spores survive 365 nm UV light?

The spore-containing materials were then subjected to harmful conditions such as exposure to UV light, X-rays, γ-radiation, and high temperatures (Fig. 5d and Supplementary Figs. 39 – 43). The spores survived 365 nm UV light treatment, but they did not survive when exposed to 254 nm light.

Can agarose spores survive desiccation stress?

The ability to survive desiccation stress was evaluated for the spore-containing printed materials. The 5% agarose material contained 92% water when printed (Methods). The water can be removed by drying and the material stored for long times (Fig. 5a). When rehydrated, it returned to its original printed shape (Fig. 5b).

Can agarose spores survive 365 nm UV light?

The spores survived 365 nm UV light treatment, but they did not survive when exposed to 254 nm light. This is expected as 254 nm UV light is known to exterminate spores 37. Spores embedded in the agarose were able to survive temperatures of 80 °C and 50 °C.
