Efficient bioethanol production from pomegranate peels by newly isolated Kluyveromyces marxianus

Pomegranate peels waste hydrolyzate optimization by Response Surface Methodology for Bioethanol production

“… Kim et al (2014) , reported the ethanol contents (g/L) 10.92–14.50 in nitric acid pretreated rice straw by Pichia stipitis . These contents were also comparable with 14.3 g/L ethanol titer obtained from acid hydrloysed PPW with Kluyveromyces marxianus ( Demiray et al, 2020 ). Current findings were far better for ethanol titer when compared with data obtained from different fruit waste viz mango, orange, date and banana ( Arumugam and Manikandan, 2011 , Boulal et al, 2016 , Maina et al, 2017 ).…”

Tangerine, banana and pomegranate peels valorisation for sustainable environment: A review

“…Choi et al [ 177 ] have reported that the fermentation of the pre-treated TPW hydrolysate has been almost completed after 12 h with an ethanol concentration of 46.2 g/L and a yield of 90.6 %. For PPW, bioethanol production using Saccharomyces cerevisiae was 5.58 g/L, using Pichia stipitis was 2.95 g/L [ 179 ] and using Kluyveromyces marxianus was 7.20 g/L [ 22 ]. For BPW, bioethanol production by Saccharomyces cerevisiae produces an bioethanol content of 4.24 g/L [ 23 ].…”

“…Every TPW, PPW and BPW valorisation pathway depends on a high number of factors affecting economic viability [ [12] , [13] , [14] ]. TPW, PPW and BPW may be used directly or after treatments as animal feed [ 15 , 16 ], soil amendment [ [17] , [18] , [19] ], bio-adsorbents [ 20 , 21 ], and the production of the outputs was obtained by the biorefinery process (biogas, bioethanol and biohydrogen) [ [22] , [23] , [24] , [25] , [26] ]. Numerous other studies have focused on the valorisation of TPW, PPW and BPW for the production of value-added products (essential oil, enzymes, food, medical and cosmetic products) [ [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] ].…”

Study on combustion, performance and exhaust emissions of bioethanol-gasoline blended spark ignition engine

“…India produces 28.65 tonnes of pomegranate fruits, of which about 30%–40% of its fruits are discarded for various reasons are stated in various literature. This organic waste and leftover of pomegranate fruits including peels, seeds and pulp can be used for the manufacture of low cost bioethanol [ 27 , 28 , 29 , 30 ]. In this work, pomegranate waste collected from the local market was used as a feedstock to extract pomegranate ethanol, resulting in lower production costs of bioethanol compared with traditional fuel sources.…”
