?-hydroxypropionic acid production by Byssochlamys sp. grown on acrylic acid

Degradation of acrylic acid by fungi from petrochemical activated sludge

“…(Figure-l). Although, acrylic acid threshold value to most microbes is 41 rag/1 (Greim et al, 1995), tolerance up to 4 -5 g/1 have been reported (Nawaz et al, 1993;Takamizawa et al, 1993). During the biodegradation transient accumulation of acetic acid and /3-hydroxy propionic acid around 4th day was observed, similar to those reported by Andreoni et al (1990), Hasegawa et al, (1982.…”

“…Basal salt medium of Takamizawa et al (1993) was used for the study. To this filter sterilized 2 g acrylic acid/1 (pH 7 with NaOH) and activated sludge from petrochemical effluent treatment plant was added and shake cultivated (350 rpm, 30°C) till visible growth.…”

“…Acrylic acid utilization by Candida rugosa (Hasegawa et al, 1982) and white molds (Takamizawa et al 1993 be due to the sodium ions as Ca(OH)2 neutralized acrylic acid as high as 10 g/1 was readily degraded. Parallel relation between growth and acrylic acid utilization was observed.…”

Transformation of Biomass into Commodity Chemicals Using Enzymes or Cells

“…271 3-Hydroxypropionic acid might be used directly in polyesters, but its potential as precursor of acrylic acid might be more interesting, because acrylic acid has an existing market. This implies that biocatalytic conversion of acrylic acid to 3-hydroxypropionic acid 272 has no clear commercial production value. Dehydration of 3-hydroxypropionic acid may be used to obtain acrylic acid (see section 9.2.2).…”

3‐Hydroxypropionic acid production by recombinant Escherichia coli ZJU‐3HP01 using glycerol–glucose dual‐substrate fermentative strategy

“…was the only native bacterium to produce 3‐HP from glycerol as the sole carbon source . Several organisms were able to produce 3‐HP from acrylic acid, 1,3‐propanediol, or propionic acid . However, these routes are commercially inefficient because the starting compounds required are even more valuable than 3‐HP.…”
