M1 and M2 are two different martensite variants with diverse elastic strain energy and lattice distortions, which transformation to austenite at different temperatures.
After Genetic background analysis of Streptomyces diastaticus No. 7 strain M1033, the modified conditions of M1033 protoplasts and transformation were established.
对7号淀粉酶菌M1033的遗传背景进行分析，建立了其原生质体制备、转化的优化条件。

The results showed that the ferrite grain can be refined by strain induced transformation.
