On-Line Measurement of Dissolved Methane Concentration During Methane Fermentation in a Loop Bioreactor

A dissolved methane sensor based on silicone tube was designed, constructed and optimized.The silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.A continuous stream of helium (50 mL/min) was directed through the tubing, sweeping out the...

The Propionic Acid Fermentation of Lactose.*

Propionic acid was one of the early products observed as resulting from bacterial action. Kearly 70 years ago (1854) Strecker (I) reported it as resulting from a fermentation of mannitol which he had studied, while Pasteur (2) also found propionic acid as one of the products formed in the fermentation of calcium tartrate. As these early observations were not made upon pure cultures, it is impos...

Destructive effects of citric acid, lactic acid and acetic acid on primary enamel microhardness

  Objective: This study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel.   Methods: This in vitro, experimental study was conducted on 24 sound primary teeth. The teeth were polished with a fine abrasive paper under running water. Tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and s...
