ATP 2G provides a novel biological indicator for improving the yield of biodegradation procedures used in purification, methanogenesis or composting.

Procedures for the biological treatment of waste water, biogas production or compost are based on controlling microbial populations that are involved in biofermentation reactions and the biodegradation of organic matter.

The effectiveness of these transformation processes depends on:

• the quality of the organic matter (nitrogen/carbon composition, absence of toxic substances and inhibitors);

• controlling the biological reactions (oxygen, temperature, humidity, pH, nutritional balance);

• the activity of the microbial populations (viability, density, diversity).

Optimizing the yield from these processes represents an important future challenge for these fields.

Bio-processing and the micro-organisms involved

• Biological processing of waste water occurs in purification facilities (water-treatment plants) in the presence or absence of oxygen due to the activity of free (activated sludges) or fixed (biofilters) aerobic or anaerobic micro-organisms.

• Methanogenesis occurs in bioreactors in the absence of oxygen due to the activity of mesophilic (grown at 35°C) or thermophilic (grown at 55°C) anaerobic bacteria.

• Composting occurs in heaps (open air mounds) and requires a constant supply of oxygen (introduced by mechanical tumbling) to activate the aerobic microbial flora.

The biomass stress index in biodegradation

The Biomass Stress Index™ (BSI in %), which corresponds to the proportion of extracellular ATP to total ATP, is a numeric indicator that describes the level of cell death and stress in a biomass involved in a biological process (or present within a facility). The higher the BSI, the greater the level of cell death.
