Direct conversion of fruit waste to ethanol using marine bacterial strain Citrobacter sp. E4

Value‐Added Products from Fruit and Vegetable Wastes: A Review

“…Zymomonas mobilis deserves special attention, as several studies have reported its advantages over S. cerevisiae for the fermentation of fruit and vegetable residues, that is, lower biomass production, higher ethanol production (up to 12% w/v) and lower process maintenance. [ 254,255 ] As demonstrated by Sarkar et al., [ 115 ] under determined conditions, Citrobacter sp. can produce ethanol (3 g L −1 ) without pre‐treating the fruit waste substrate, which is an important advantage regarding the waste processing procedure.…”

“…For example, Sarkar et al. [ 115 ] carried out a fractional distillation, with a simple column, of a fermentation broth from fruit wastes to obtain a yield of 0.3 g of ethanol from 1 g of fruit residues. Borah and Mishra [ 262 ] distilled fermented apple pomace and banana waste on a laboratory scale, obtaining concentrated bioethanol (48%).…”

Production, purification, and process optimization of intracellular pigment from novel psychrotolerant Paenibacillus sp. BPW19

“…The final elongation is terminated with an extension of 10 min. The PCR amplified product was purified using a gel extraction kit (Genetix Biotech Asia Pvt Ltd, New Delhi, India) and Sanger sequencing was performed from Eurofins Genomics India Pvt Ltd, Bangalore, India [ 46 ]. The obtained sequence was edited using BioEdit (v7.0.5) software to remove terminal noise response during the sequencing.…”

Trends in mitigation of industrial waste: Global health hazards, environmental implications and waste derived economy for environmental sustainability

“…Furthermore, 2% (v/v) culture of S. cerevisae produced 0.316 g bioethanol from fruit and vegetable waste (Sindhu et al, 2020). A recent study showed that sequential cultivation of thermophilic bacteria, It was recorded that strain E4 produced 0.13 g of ethanol/g of waste whereas 0.30 g of ethanol/g waste was produced after optimizing the process parameters (Sarkar et al, 2019). Jugwanth et al (2020) reported the valorization of sugarcane bagasse for bioethanol production by Saccharomyces cerevisae through saccharification and fermentation process, the yield was recorded to be 4.88 g/L (Jugwanth et al, 2020).…”
