Microbial Physiology and Biochemistry Laboratory

'...Each experiment is set out with clearly defined goals, a brief introduction, and the materials that will be required...This is an adequate laboratory manual with a wide range of experiments...' David J.Kelly, Jnl of Antimicrobial Chemotherapy (1998) 42
