Abstract

Abstract: Biological hydrogen production is under extensive investigation worldwide and has attracted the interest of researchers in a number of disciplines including the fundamental sciences, e.g., microbiology and biochemistry, and the applied sciences, e.g., chemical engineering. While the multidisciplinary approaches being used have been very fruitful in terms of advancing biohydrogen research, the data sets rapidly accumulating in the published literature are often difficult to compare due to the use of different units, or the incomplete description of experimental conditions. Here we review some of the common methods that are used in various aspects of biohydrogen research and suggest ways of reporting data that enable conversion to other units and comparison with similar research being carried out elsewhere. In addition, we have compiled in one place common abbreviations and definitions as well as useful physical/chemical constants and laws pertaining to hydrogen. Unlike other reviews that examine the results of specific studies, or describe the different systems being deployed and compare them, here we provide in one place for the first time a detailed listing and description of the up-to-date methods used in measurement and quantification of biohydrogen production. Useful conversion factors and physical constants are also given. Highlights: Different ways of reporting data resulting from biological hydrogen production. General substrate consumption and product formation analysis in biohydrogen production. Detailed measurement methods for light intensity and biomass. Parameters specific to dark/photo fermentation and MECs delineated. Physical/chemical constants and laws pertaining to hydrogen given in one place.
