Screening and preliminary application of microbial strains for bio-retting of false stem of Musa nana Lour
摘要
Abstract
[Objective]Preliminary studies on bio-retting of false stem of banana (Musa nana Lout) were carried out using microbial strains in order to provide basis for the practical application of bio-retting technique in extracting fibers from false stem of banana. [Method]Microbial strains for bio-retting were isolated from false stem of rotten banana plants and soil. The strains were screened and superior ones were used in the bio-retting experiment. Their bio-retting performance was assessed comprehensively by determining false stem weight-loss ratio, fiber yield and the rate of residual gum in fiber. [Result]Two strains, viz., FR1 and BR2-1, having good ability for bio-retting false stem of banana, were screened out. The time for bio-retting of stem taken by these strains was found to be 72 h. The rates of gum in false stem, bio-retted by FR1 and BR2-1, decreased rapidly from 83.6 to 24.7 and 20.2% , respectively. The weight-loss ratio of false stem reached 72.9 and 77.8%, and the yields of fiber recorded as 2.27 and 2.01%, after bio-retting of false stem by strains FR1 and BR2-1, respectively. [Conclusion]The screened microbial strains FR1 and BR2-1 showed good application potential for bio-retting of banana false stem, therefore, may be used for bio-retting of banana false stem for the removal of gum and extraction of fibers.关键词
