“…vegetable oils (17)(18)(19)(20) have been used for organic phase formation. Moreover, novel extractants have recently been used instead of conventional extraction agents (21)(22)(23)(24). It has been shown that reactive extraction is applicable for separating carboxylic acids of similar structures from their mixed solutions (25).…”

Combined use of inert diluents with polar modifiers enables former to be utilized for the recovery of polar value-added chemicals. The results show that polarities of both solvent and modifier are critical for efficient separations. Thus, K D values with 1-octanol were higher than those with 1-decanol; while those with xylene were superior to those with hexane and toluene.Increasing amine concentrations increased the K D values, in contrast to the trends with pH and temperature. About 33%, 79% and 67% of acetic acid was recovered using 25% (v/v) Alamine 336 in xylene, 1-octanol and 30% 1-octanol-modified xylene, respectively.A c c e p t e d M a n u s c r i p t 2 Therefore, solvent modification positively affects the extraction power of inert diluents for acetic acid recovery.

“…However, the use of a solvent with low miscibility in aqueous phase (0.039 mass %) minimizes environmental pollution. Krzyzaniak et al (2013) studied novel extractants for the recovery of fermentation derived LA. The aim of this study was to develop extractants with a higher affinity for carboxylic acids than trioctylamine.…”

Lactic acid is an important platform chemical with a wide range of applications. Production of lactic acid by fermentation is advantageous because renewable and low cost raw materials can be used as substrates. After fermentation, the broth needs to be purified to obtain pure lactic acid for further uses. Thus, efficient downstream processes are very important because they account for 50% of the production costs. This review discusses different processes that are currently employed for lactic acid recovery, focusing on precipitation, solvent extraction, and separation with membranes. Advances in such recovery processes and drawbacks that limit the application of these technologies at the industrial level are also presented.

“…Resin adsorption has also been used to recover lactic acid from fermentation broth in a study by Wang et al, where microfiltration membrane integrated with fermenter was used to relieve product inhibition and to extend cell growth period from 4 to 120 h [191]. Reactive liquid-liquid extraction is another promising technology that has been studied for lactic acid recovery and recently, a new extractant, N,Ndidodecylpyridin-4-amine, was developed that has the highest distribution coefficient of lactic acid and back extraction was feasible at elevated temperatures with single stage recoveries up to 80 % using heptane as an anti-solvent [79].…”

Advances in science and technology have resulted in the rapid development of biobased plastics and the major drivers for this expansion are rising environmental concerns of plastic pollution and the depletion of fossil-fuels. This paper presents a broad view on the recent developments of three promising biobased plastics, polylactic acid (PLA), polyhydroxyalkanoate (PHA) and polybutylene succinate (PBS), well known for their biodegradability. The article discusses the natural and recombinant host organisms used for fermentative production of monomers, alternative carbon feedstocks that have been used to lower production cost, different metabolic engineering strategies used to improve product titers, various fermentation technologies employed to increase productivities and finally, the different downstream processes used for recovery and purification of the monomers and polymers.
