Research on the Promotion of Sludge Anaerobic Fermentation with Sodium Citrate under Low Concentrations of Polyaluminum Chloride

open access: yesFermentation, 2023
Polyaluminum chloride (PAC) is used widely and increasingly in wastewater treatment plants, resulting in its inevitably high production in sludge. Previous studies have indicated that the production of short-chain fatty acids (SCFAs) is inhibited by the ...

Influence of Animal/Plant Activated Biochar Properties on Methane Production from Corn Stalk by Anaerobic Fermentation

open access: yes, 2022
Activated biochar (ABC) was prepared from typical plant/animal biochar (pig bone biochar/corn stalk biochar) by optimizing the gas production characteristics of anaerobic fermentation. The effects of the physical and chemical properties (specific surface

Aeration and Sodium chloride in the develop of microflora and phycochemical parameters on the Olea europaea L. cv Sevillana fermentation at the natural black style in La Yarada zone-Tacna

open access: yesGrasas y Aceites, 2013
The aerobic fermentation of the table olive variety, Sevillana a black style, was carried out, taking into account the parameters of fermentation of fixed acidity between 1.2 to 1.5% and depended on the chloride concentration in the brine.

Thermotoga lettingae sp. nov., a novel thermophilic, methanol-degrading bacterium isolated from a thermophilic anaerobic reactor [PDF]

open access: yes, 2002
A novel, anaerobic, non-spore-forming, mobile, Gram-negative, thermophilic bacterium, strain TMO(T), was isolated from a thermophilic sulfate-reducing bioreactor operated at 65 degrees C with methanol as the sole substrate.

Rapid fermentation testing of anaerobic bacteria [PDF]

open access: yesJournal of Clinical Microbiology, 1976
Rapid tests for glucose, maltose, lactose, sucrose, and starch fermentation were performed on 112 strains of anaerobic bacteria. The tests were incubated under aerobic conditions, and results were read within 4 h. An overall correlation of 89% was achieved between the rapid tests and the Virginia Polytechnic Institute method.

Energy Conservation in Fermentations of Anaerobic Bacteria [PDF]

open access: yesFrontiers in Microbiology, 2021
Anaerobic bacteria ferment carbohydrates and amino acids to obtain energy for growth. Due to the absence of oxygen and other inorganic electron acceptors, the substrate of a fermentation has to serve as electron donor as well as acceptor, which results in low free energies as compared to that of aerobic oxidations.
