Figure 6: Modified Weibull distribution of the fibres’ average tensile strength.
From: Study of the tensile properties of individual multicellular fibres generated by Bacillus subtilis

(a,b) Tensile strength at low RH. Weibull distribution parameters can be obtained by fitting the experimental data to the linear function in equation (6) using the least-squares method. For multicellular fibres with three genes deleted, their Weibull modulus m and average tensile strength are 2.1 and 63.3 MPa, respectively; for multicellular fibres with two genes deleted, they are 1.8 and 82.5 MPa, respectively. (c) Tensile strength at high RH. The parameters m and
are 1.7 and 33.7 MPa, respectively, for fibres with three genes deleted.
