DCE01菌株大麻韧皮脱胶过程中有机酸的变化规律
The Change Rule of Organic Acids during the Degumming of Hemp Bast with the Strain of DCE01
摘要
Abstract
To elucidate the mechanism of bio-degumming of hemp bast,the hemp bast was degummed with the strain of DCE01 for 10.5 h.After 0.5 h,the samples were analyzed by HPLC every 2 h.The main results were as follow:The main constitutes were oxalic acid,methanoic acid,malic acid,lactic acid,citric acid,acetic acid,succinic acid,propionic acid and some other unknown organic acids.The content of oxalic acid,methanoic acid,and succinic acid increased and then decreased,the results were 93.69％ decreasement,65.37％ increasement and 26.01％ decreasement,respectively.The content of acetic acid increased firstly and then decreased,and subsequendy increased firstly and then decreased again,and the results was 84.58％ decreasement.The content of lactic acid and malic acid increased firstly and then decreased,subsequently increased again,the results were 52.03％ increasement and 31.97％ increasement,respectively.The content of citric acid increased steadily then reached the maximum,the result was 4.31％ increasement.The content of propionic acid was not regular,and the result was 0.11％ increasement.关键词
