Inoculum preparation for biogas generation

The most cheapest and easiest way to produce an inoculum is using digestate from working biogas digester. They are consist of active culture with stable activity because consist of varieties of microbes working together or consortium.

Next source is by taking a scoop of slurry or sediment from anaerobic pond. These are also active microbes we can used directly to produce biogas.

If you happen to live nearby cattle farm, dung is another source of microbes that can produce biogas.But to start with cow dung we need to mix it with water and ferment until it mature in which produces biogas.

Do not mistaken biogas with carbon dioxide. Biogas is flammable while CO2 is not.

So to produce biogas you can start with things that already around you.
