Bioaugmentation with Enterococcus casseliflavus: A Hydrogen-Producing Strain Isolated from Citrus Peel Waste

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

“…The production of bio-H 2 is influenced by several physicochemical factors of the wastes used and also by environmental factors such as pH, temperature, and the type of pre-treatment used [ 196 ]. Many studies have focused specifically on the production of bio-H 2 from food wastes, whereas there is only some studies investigating the production of bio-H 2 from citrus peels and BPW, such as the study by Camargo et al [ 26 ] which has demonstrated a high bio-H 2 production (13.9 mmol.L −1 ) in the bio-enhancement trial using Enterococcus casseliflavus and citrus peel waste as a carbon source, and also the study by Nathoa et al [ 199 ] which has indicated the bio-H 2 production from BPW by two-phase anaerobic fermentation and produced a yield and hydrogen content of 209.9 mL.g −1 VS and 35 % respectively. Although there are a lot of researches concerning the conversion of agri-industrial wastes into Bio-H 2 by dark fermentation processes.…”

“…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] ].…”
