DESCRIPTION:Biogeochemical reaction modeling (BGRM) is a computational fra
 mework that couples the simulation of microbial metabolism with the simula
 tion of chemical reactions. BGRM simulates chemical reactions using the cl
 assical approaches of geochemical reaction modeling. Specifically\, it bui
 lds on the equilibrium simulation of chemical speciation\, and applies kin
 etic or equilibrium modeling approach to redox reaction\, mineral precipit
 ation and dissolution\, and other chemical reactions. BGRM simulates the m
 etabolism of microbial groups in terms of the rates of microbial respirati
 on/fermentation\, growth\, and maintenance. It describes microbial rates u
 sing rate laws that consider the availability of electron donors\, accepto
 rs\, and growth nutrients\, the thermodynamics of the environment\, and th
 e energetics of microbial metabolism. By capturing the thermodynamics and 
 kinetics of chemical and microbial reactions\, BGRM can be applied to asse
 ss the habitability and potential metabolic activit ies of natural environ
 ments\, and to predict the dynamics of microbial populations and environme
 ntal chemistry. By simulating simultaneously chemical and microbial reacti
 ons\, BGRM can also be applied to investigate the interactions among diffe
 rent microbial groups\, and between microbes and their environment. \n
