Response surface graphs representing the effect of Time (A), Sucrose (B), Salt (C) and metal (D) on the responses. A Relative effect of Time and sucrose on SM production at constant salt and metal levels (B) Relative effect of Time and salt factors on SM production at constant sucrose and metal ions (C) Relative effect of time and metal ions on SM production while keeping sucrose and salt as a constant factor (D) Relative effect of sucrose and salt on SM production with time and metal ions as constant (E) Relative effect of sucrose and metal on SM production with time and salt as constant (F) Relative effect of salt and metal on SM production with time and sucrose as constant
