Bacillus subtilis NCIB 3610 amyE::PtapA-Ypet strain (ES2107) was used for all experiments. The strain was cultured on lysogeny broth (LB)-agar plates prepared from Miller LB (Acros Organics, Fair Lawn, NJ) and 1.5% agar powder (Molecular Genetics, Fisher Scientific, Waltham, MA). LB agar plates were streaked with B. subtilis ES2107 from frozen stocks and incubated at 30°C for 15 h.
B. subtilis biofilms were grown on MSgg, a B. subtilis biofilm-promoting medium (5 mM potassium phosphate [pH 7]) (Fisher Scientific, Waltham, MA), 100 mM MOPS (morpholinepropanesulfonic acid [pH 7]) (Sigma-Aldrich, St. Louis, MO), 2 mM MgCl2 (Fisher Scientific, Waltham, MA), 700 μM CaCl2 (Alfa Aesar, Haverhill, MA), 50 μM MnCl2 (Fisher Scientific, Waltham, MA), 50 μM FeCl3 (Sigma-Aldrich, St. Louis, MO), 1 μM ZnCl2 (Sigma-Aldrich, St. Louis, MO), 2 μM thiamine hydrochloride (Fisher Scientific, Waltham, MA), 0.5% glycerol (Fisher Scientific, Waltham, MA), and 0.5% glutamate (Sigma-Aldrich, St. Louis, MO). For MSgg agar plates, 1.5% agar (BD) was added to the medium, and approximately 5-ml plates were poured.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
