Fresh banana pseudo-stems as a tropical lignocellulosic feedstock for methane production

Abstract

Background: The banana pseudo-stem is a low-lignin-content lignocellulosic biomass that can be used for methane production. In recent years, anaerobic digestion (AD) of dried banana stems for methane production has attracted considerable attention. However, there is limited information regarding methane production from the fresh banana pseudo-stem. The direct usability of fresh banana stems as a resource for renewable energy production through AD is a called upon prerequisite for an improved waste management system culminating in a sustainable as well as socioeconomic development of local banana-producing communities. Methods: In this study, three series of experiments were performed simultaneously to investigate the methane production from fresh banana pseudo-stems for the first time. The tests included size reduction, enzyme addition, and co-digestion of banana stems with cow manure.

Enzymatic Hydrolysis and Fermentation of Banana Pseudostem Hydrolysate to Produce Bioethanol

“…e cellulose content of the untreated BPS (24.5%, Table 1) was comparable to 20.1% reported by Guerrero et al [45]. Several authors reported between 30 and 44% cellulose, 15 and 30% hemicellulose, and 6 and 12% lignin in the untreated BPS [13,21,37,[46][47][48].…”

Biodegradable Cellulose Film Prepared From Banana Pseudo-Stem Using an Ionic Liquid for Mango Preservation

“…The inedible parts, including pseudo-stems and leaves, representing about 88% of the weight of the whole plant (Reddy and Yang, 2015), are discarded as wastes. China alone will generate about 29.0 million tons per year of banana stalk residues (Li et al, 2016). The banana pseudo-stem has a high cellulose fiber content (Guimarães et al, 2009).…”

Table 1 ( 12 - 27 ) shows examples of lignocellulosic and non-lignocellulosic residues from agricultural and agro-industrial sectors, with the obtained biogas yields.…”
