Abstract Banana Pseudo stem waste after each harvest contributes about 70–80 Milli Tons Per hector. The banana pseudo stem will be thrown as waste biomass after each harvest as it is unstable for the upcoming harvest. The biggest challenge in banana cultivation is the utilization of biomass of banana pseusostem waste into valuable products. In this study, Xylano-pectinase enzyme extract was produced from banana pseudo stem waste under solid-state fermentation by Enterobacter cloacae PMC04. The highest pectinase and xylanase activities obtained using banana pseudo stem as carbon source were 124.62 U/ml and 173.81 U/ml respectively. Thermodynamics stated that range 40-50oC were considered to be the optimal temperature for xylano-pectinase enzyme production and subsequent degumming of banana fibers. The crude enzyme extract were then used in the degumming of banana fibers for textile application. Textile processing of banana fiber necessitates the removal of hemicellulose substance which can be achieved by crude xylano-pectinase enzyme. It was found that crude xylano-pectinase was efficient in the removal of hemicellulose substance from the fibers. Results obtained from this study demonstrate that the proposed bioprocess could be successfully applied for the degumming of banana fibers sustainably.

Cupuaçu (Theobroma grandiflorum Schum) is an Amazonian Basin native fruit whose fruit pulp is consumed as a juice which presents high density, viscosity, and turbidity. Pectic enzymes, usually yielded by microorganisms, are used to reduce the juice viscosity and turbidity. The present study aims to evaluate the use of pectic enzymes when processing cupuaçu juice. The cupuaçu juice was obtained by using Aspergillus japonicus 586 crude enzyme extract and incubation at 50°C with agitation (140 rpm) for one hour. Enzyme activities were determined, and the juices were evaluated as to their yield, turbidity, viscosity, and chemical composition. The juice produced by using crude enzyme extract presented higher soluble solids, reducing sugars, and lower viscosity and turbidity.

Ten day old potted rooted cutting of sweetpotato genotypes `Travis' and MS 21-1 were exposed for seven days to cold (12°C) or 21°C (control) temperatures. Chemical changes that may accompany tolerance or susceptibility to chilling were monitored. No consistent differences in total fatty acid composition were found between the two genotypes. There was an increase in peroxidase (POD) activity of the crude enzyme extract for MS 21-1, the chilling tolerant genotype, when exposed to 12°C for seven days. No differnces were found in POD activity for `Travis', the chilling sensitive genotype. Superoxide dismutase (SOD) and catalase (CA) activity for crude enzyme extracts did not differ between genotypes and was not influenced by storage temperature.
