Evaluation of biomass concentration is an important problem encountered in many microbial and other bioprocesses. It determines the catalytic activity of the microbial cell in a given time. Various direct and indirect methods for the estimation of biomass have been developed using physical and biochemical techniques.

The reasons for and historical backgrounds of biomass determination are discussed under the aspects of theoretical and practical importance, usefulness and representativity. Off-line methods are evaluated and compared with on-line methods; constraints of applications and conclusiveness of results are rated.

'Biomass Lung': Primitive Biomass Combustion and Lung Disease
Indoor and Built Environment, 2002Domestic burning of biomass fuel is one of the most important risk factors for the development of respiratory diseases and infant mortality. The fuel which causes the highest level of disease is dung. In the rural areas of developing countries some 80% of households rely on biomass fuels for cooking and often heating as well and so suffer high indoor ...

Pyrolysis characteristics of biomass and biomass components
Fuel, 1996Biomass pyrolysis studies were conducted using both a thermogravimetric analyser and a packed-bed pyrolyser. Each kind of biomass has a characteristic pyrolysis behaviour which is explained based on its individual component characteristics. Studies on isolated biomass components as well as synthetic biomass show that the interactions among the ...

Processes for refining biomass from trees or from agricultural residues are fast approaching commercialization. Advances have been made in acidic and enzymatic hydrolysis of the cellulose component of biomass and in some newer processes for biomass refining which leave the lignin fraction relatively intact.

Pretreatment of Biomass for Thermochemical Biomass Conversion
1985Developers of microbiological processes to convert biomass into chemicals and fuels recognized long ago that pretreatments were needed prior to fermentation or enzyme reactions, if high rates and yields are to be achieved.1,2 Microorganisms and enzymes have difficulty in depolymerizing crystalline polymers, such as cellulose, and hydrophobic molecules,
