Glycerol or crude glycerol as substrates make Pseudomonas aeruginosa achieve anaerobic production of rhamnolipids [PDF]

Microbial Cell Factories, 2021
Abstract Background The anaerobic production of rhamnolipids is significant in research and application, such as foamless fermentation and in situ production of rhamnolipids in the anoxic environments. Although a few studies reported that some rare Pseudomonas aeruginosa strains can produce rhamnolipids anaerobically ...

Esterification of Free Fatty Acids with Glycerol within the Biodiesel Production Framework [PDF]

, 2019
Companies in the field of the collection and treatment of waste cooking oils (WCO) for subsequent biodiesel production usually have to cope with high acidity oils, which cannot be directly transformed into fatty acid methyl esters due to soap production.

Production of PHB from Crude Glycerol

Engineering in Life Sciences, 2007
AbstractCrude glycerol – a by‐product of the large scale production of diesel oil from rape – is examined for its possible use as a cheap feedstock for the biotechnological synthesis of poly(3‐hydroxybutyrate) (PHB). The glycerol samples of various manufacturers differ in their contamination with salts (NaCl or K2SO4), methanol or fatty acids.

Utilization of Crude Glycerol Waste from Biodiesel Production as an Additive to Improve the Quality of Tea Dreg Biopellet

Jurnal Teknik Pertanian Lampung, 2023
Biodiesel production using the transesterification method generates a large amount of crude glycerol as by-products. Crude glycerol waste can be reused and utilized as an additive in the formulation of biopellet.
