We would like to acknowledge the contributions of Patrick Perry and the late David Williams for their expert advice and permission for use plants from the UK variety trials. This paper reviews the use of organisms and enzymes for (a) extraction of fibres from plant material (retting), (b) surface modification of fibres, and (c) end-of-life treatments. Basic methods include dew retting and water retting. For field retting a classification of the microbial evolution (by gene sequencing) and enzyme profiles were conducted. The plants are immersed in water and when they swell, inoculated with bacteria which hydrolyze pectic substances of the cell walls and separate the fibres. Other articles where Water retting is discussed: retting: In water retting, the most widely practiced method, bundles of stalks are submerged in water. Retting is indeed a natural process, and may be regarded as merely a step in the cycles of the elements. This is distinct from the process of water retting, used mainly for textile quality fibers, in which the stalks are submerged in water which may contain additional enzymes and/or microbial cultures . ; Bennett, M.

Classical field retting and controlled fungal retting of hemp using Phlebia radiata Cel 26 (a mutant with low cellulose degrading ability) were compared with pure pectinase treatment with regard to mechanical properties of the produced fibre/epoxy composites. ; Highlander, S.K. The microbiology of bast fiber retting has long been of interest to the scientific community, and increasingly-sophisticated techniques have been used over the years to better understand the diversity of the main actors: bacteria and fungi. The resiliency of the bacterial community itself is ecologically interesting, and may provide a platform on which to study the concepts of resistance and resiliency in retting communities according to environmental disturbance and/or attempts to alter the community thorough applications of specific materials such as fungal/bacterial inoculum [. Clostridium butyricum is used in the process and these bacteria hydrolyze the middle lamella of these plant fibres. Liu, M.; Fernando, D.; Meyer, A.S.; Madsen, B.; Daniel, G.; Thygesen, A. Industrial Hemp: Renewed Opportunities for an Ancient Crop. To our knowledge, research into which microorganisms may be endophytes living within the stalks and which are surface dwelling has not been done. Microbes are used in retting to obtain bast fibres. 10. RESULTS Ofthe different sporeformingaerobic bacteria identi- fied as Bacilluspolyrnyxa,Bacillus subtilis, Bacillus cereus, Bacillus sphaericus, Bacillus lentus, andBacilluts pumilus,the only bacterium found to ret jute was Bacillus polymyxa. Segata, N.; Izard, J.; Waldron, L.; Gevers, D.; Miropolsky, L.; Garrett, W.S. At T1, the SSa variety showed significantly lower alpha diversity values than FE and/or FU (, Treatments (LM, HM, SHM) within each variety (FE, FU, SSa) and among all varieties were compared over time and at each time point. Specifically for fiber use, problems hinge around issues of scale and economy, in which the retting and decortication process has been described as a âbottleneckâ for supplying consistent product to industry manufacturers [, This work, together with past and recent studies of bast fiber retting, indicate that hemp (as well as other common bast fiber plants) harbor a resilient cohort of microorganisms that appear to be present at harvest and continue to persist throughout the retting process. �_�$��*������iG�d[N��M��J3.�,8p�R�m٫�? In retting flax man has simply made use ⦠However, it is far less labor intensive and less expensive than water retting.

Dew retting tends to yield a dark-colored fiber. Flint, H.J. (2011). Information about how these factors affect the microbial population involved in the retting process and whether or not it differs by variety can lead to improvements in the quality and value of field-retted hemp, thereby increasing profitability for farmers and encouraging the inclusion of more natural fibers in industry and manufacturing. This study is a first step before selection and isolation of strains that could later be used to optimise microbial retting efficiency and hence fibre quality. Results were analyzed based on knowledge of the cell wall active enzymes produced by the two fungi. hemp microbiome; fiber crops; fiber retting, Help us to further improve by taking part in this short 5 minute survey, Arbuscular Mycorrhizal Fungi Associated with Rice (, Present Status and Perspective on the Future Use of Aflatoxin Biocontrol Products, Drivers of Microbial Diversity and Roles in Agroecosystems, http://microbe.med.umich.edu/services/microbial-community-analysis, http://creativecommons.org/licenses/by/4.0/. Fibre are extracted by retting methods, viz. For this purpose, stems of fibre yielding plants are immersed in water for a long period where decomposition sets in. For hemp fiber crops in particular, one of the main problems that has been identified by farmers and fiber processors concerns field retting, also known as dew retting, whereby hemp stalks are cut and left in the field for a period of time before baling.
