BMP Bottle Setup Information

Description

Details on bottle contents and more from GD-BMP experiment.

Usage

data("UQGDSetup")

Format

A data frame with 135 observations on the following variables.

id

identification code, a unique value for each bottle in the dataset. A factor.

descrip

description of substrate, a factor with levels Inoculum, Cellulose, Substrate C.

m.inoc

mass of inoculum added to the bottle at the start in g. Numeric.

m.sub

mass of substrate added to the bottle at the start in g. Numeric.

m.tot

total mass added to the bottle at the start in g. Numeric.

m.sub.vs

mass of volatile solids (VS) of substrate added to the bottle at the start in g. Numeric.

vol.hs

bottle headspace in mL. Numeric.

isr

VS-based inoculum-to-substrate ratio.

Details

These data are meant to be example data for calcBgGD, for gas density-based determination of biogas production (GD-BMP). Reactors were glass serum bottles with butyl rubber septa. Data in UQGDBiogas are from the same bottles.
