Isolation and Identification of Dominant Strains Causing Rice Yellowing and Their Effects on the Content of Amino Acids in Rice
The problem of rice yellowing in storage has been deeply concerned by people.Many factors can cause rice yellowing.In addition to the influence of temperature and humidity,microorganisms also play a subtle role in the process of rice yellowing.The dominant strain that can cause yellowing of rice was isolated and purified from naturally yellowing rice.Through the morphological observation and molecular biological analysis of the strain,the dominant yellowing strain was finally determined as Coriolopsis trogii.The results of amino acid analysis indicated that the pro-portion of alanine,valine,leucine,phenylalanine and arginine in the total amino acids in the yellowing process of rice showed a downward trend with the deepening of yellowing degree,which may be related to the yellowing process of rice.This experiment effectively established the relationship between fungal infection and rice yellowing,and pro-vided some reference for the prevention and control of rice yellowing caused by fungal infection.
