G'day Steven, Yes, no methanogens = no methane! This is what happens in silage heaps on farms. Cow manure has methanogens so becomes the inoculum, inoculum can also come from another digester (but cows are often closer).
In your situation of periodic clean outs a batch system is more sensible, as with plug flow you need to add raw material at least daily for reasonable operation (and if you store the substrate it will still decompose and so you lose methane potential anyway). Hope this helps, HOOROO Mr. Paul Harris, Room 202 Charles Hawker Building, Faculty of Sciences, The University of Adelaide, Waite Campus, PMB 1, Glen Osmond SA 5064 Ph : +61 8 8303 7880 Fax : +61 8 8303 4386 mailto:[email protected] http://www.adelaide.edu.au/directory/paul.harris CRICOS Provider Number 00123M This email message is intended only for the addressee(s) and contains information that may be confidential and/or copyright.

And pardon my ignorance, I'm trying to get my learning curve up as soon as I can! Does a lack of methnogens mean that it cannot produce methane (surely not) ... or that in terms of an innoculum it can not produce that activated culture, and a cow manure, with some straw should be added to produce the innoculum? Also what factors in this would differ with a batch load (our plan) as opposed to a plug flow? Thanks!
