“…Cavendish) at low cooking temperature of 105°C utilizing formic acid and acetic acid also yields better quality pulp for papermaking (Mire et al 2005). Papers made from banana were reported to have a very low water absorption capacity making it more water resistant and stronger than wood-pulp paper (Jacob and Prema 2008).…”

Banana (Musaceae) is one of the world's most important fruit crops that is widely cultivated in tropical countries for its valuable applications in food industry. Its enormous by-products are an excellent source of highly valuable raw materials for other industries by recycling agricultural waste. This prevents an ultimate loss of huge amount of untapped biomass and environmental issues. This review discusses extensively the breakthrough in the utilization of banana by-products such as peels, leaves, pseudostem, stalk and inflorescence in various food and non-food applications serving as thickening agent, coloring and flavor, alternative source for macro and micronutrients, nutraceuticals, livestock feed, natural fibers, and sources of natural bioactive compounds and bio-fertilizers. Future prospects and challenges are the important key factors discussed in association to the sustainability and feasibility of utilizing these by-products. It is important that all available by-products be turned into highly commercial outputs in order to sustain this renewable resource and provide additional income to small scale farming industries without compromising its quality and safety in competing with other commercial products.

“…SPJ was found to be very effective as it could grow on the wetted flax fibers only (without any other nutrient) and resulted in such a good pectinase activity and degumming. Saikia et al (2009) reported 10.4% and 9.7% of residual gum reduction in ramie fibers after 4 and 6 days treatment, Jacob and Prema (2008). Figure 3 depicts the similar growth pattern of Pseudozyma sp.…”

“…Degumming of ramie (Cao et al 1992;Bruhlmann et al 1994;Kapoor et al 2000;Zheng et al 2001;Basu et al 2009), banana fibers (Jacob and Prema 2008), pineapple leaf fibers (Deng et al 2009) and buel (Kashyap et al 2001b) fibers with pectinase from bacteria has been reported earlier but a good amount of gum reduction of flax fibers with a yeast alkaline pectinase with such a low enzyme dose and short treatment time is reported for the first time.…”

A cellulase free, alkaline, thermo-tolerant pectinase was produced by a novel yeast strain Pseudozyma sp. SPJ using citrus peel as inexpensive carbon source. The crude enzyme showed good prospects in degumming of flax fibers for textile industry. An optimum pectinase dose of 80 U g -1 resulted in reduction of 15 ± 1.92% dry weight of the fibers, releasing maximum galacturonic acid (10825.5 ± 34.2 lg g -1 dry fiber) after the incubation of 6 h. The yeast culture could grow on the flax fibers (as sole carbon source) without addition of any other nutrient and produce good enzyme yield (9235.5 ± 21.51 U g -1 dry fiber). After 12 h incubation of the fibers with the isolated yeast strain, 4471 ± 19.5 lg g -1 dry fiber galacturonic acid was achieved with maximum weight loss of 11 ± 1.2%. This process reduced the amount of chemicals and energy used in conventional methods. It also contributed to enhance fineness and overall quality of the fiber strands. This study is relevant to the textile industry as it provided a fast, economical and eco-friendly method for degumming of flax fibers.

“…This process removes the heavily coated non-cellulosic natural binding material from the cellulosic part of the fibre. 9 The main mechanical extraction methods are the Bacnis and Leonit processes. In the Bacnis process, a simple stripping action is used to pull apart the trunks and to undress the sheath.…”

This article presents the strength, diameter, elongation and tenacity variations of banana pseudo-stem fibres extracted from five common Sri Lankan cultivars. The banana plants that were selected represent the dry and wet climatic zones of Sri Lanka. Mixtures of all layers of stem from the selected cultivars were subjected to three different extraction methods. Decortication technique was used for mechanical extraction, sodium hydroxide was used for chemical extraction and pectinase enzyme was used for biological extraction. The mechanical extraction method resulted in coarser fibres, chemical extraction resulted in a 30% reduction in the fibre diameter, while the biologically extracted fibre presented a 40% increase in fibre strength compared with the mechanically extracted fibres. Scanning electron microscopy analysis revealed the presence of damaged fibrils in mechanical extraction and removal of binder material in the chemical and biological extraction methods. Furthermore, Fourier transform infrared spectroscopy analysis proved the removal of lignin in chemical and biological extraction. Different cultivars presented different behaviours in extensibility, which is common in natural fibres.
