Recent Advances and Challenges towards Sustainable Polyhydroxyalkanoate (PHA) Production
Constantina Kourmentza,Jersson Plácido,Nikolaos Venetsaneas,Anna Burniol-Figols,Cristiano Varrone,Hariklia N. Gavala,Maria A.M. Reis +6 more
TL;DR: In this paper, challenges and opportunities regarding polyhydroxyalkanoate production are presented and discussed, covering key steps of their overall production process by applying pure and mixed culture biotechnology, from raw bioprocess development to downstream processing.
Journal ArticleDOI
Bacterial Cellulose Production from Industrial Waste and by-Product Streams
Erminda Tsouko,Constantina Kourmentza,Dimitrios Ladakis,Nikolaos Kopsahelis,Ioanna Mandala,Seraphim Papanikolaou,Fotis Paloukis,Vítor D. Alves,Apostolis A. Koutinas +8 more
TL;DR: It is demonstrated that by-product streams from the biodiesel industry and waste streams from confectionery industries could be used as the sole source of nutrients for the production of bacterial cellulose with similar properties as those produced with commercial sources of nutrients.
Journal ArticleDOI
Exploitation of olive oil mill wastewater for combined biohydrogen and biopolymers production
Ioanna Ntaikou,Constantina Kourmentza,E. C. Koutrouli,Katerina Stamatelatou,A. Zampraka,Michael Kornaros,Gerasimos Lyberatos +6 more
TL;DR: The present study aimed to the investigation of the feasibility of the combined biohydrogen and biopolymers production from OMW (Olive oil Mill Wastewater), using a two stage system, and found that the dominant PHA produced is polyhydroxybutyrate.
Journal ArticleDOI
Burkholderia thailandensis as a microbial cell factory for the bioconversion of used cooking oil to polyhydroxyalkanoates and rhamnolipids.
Constantina Kourmentza,Jeferson B. da Costa,Zélia Azevedo,C. Servin,Christian Grandfils,V.P. de Freitas,Maria A.M. Reis +6 more
TL;DR: The present work assessed the feasibility of used cooking oil as a low cost carbon source for rhamnolipid biosurfactant production employing the strain Burkholderia thailandensis, and is the first study reporting the simultaneous production of polyhydroxyalkanoates and rham nolipids by the non-pathogen rhamNolipID producer B. th Thailandensis.
Journal ArticleDOI
Spent coffee grounds make much more than waste: exploring recent advances and future exploitation strategies for the valorization of an emerging food waste stream
TL;DR: In this article, several scenarios, regarding the exploitation of this low-cost feedstock with huge valorization potential, are presented via either physicochemical or biotechnological routes.
