91. The results showed that alkali lignin of rice straw is a good fertilizer raw material. It has high dissociable humic acid content and good fertilizer efficiency.

92. In Han lignin that direct way, higher reliability, more convenient and safe.

93. The results showed that the lignin in the unbleached pulp was mainly composed of syringyl lignin (S-lignin) and guaiacyl lignin (G-lignin).

94. Flax is an important bast fiber crop(sentencedict.com), and lignin has a greater impact on performance and quality of flax fibers.

95. This article summarized the research development of the reaction characteristic between lignin quinonoid chromophoric group and hydrogen peroxide.

96. The residual sugar contents containing in HBS lignin were tested by colorimetric analysis of DNS (3,5 -dinitrosalicyclic acid) and direct titration.

97. Dispersants such as lignin type, naphthalene sulfonate - formaldehyde condensates and polycarboxylic acids were introduced.

98. The organic agents prescription of lignin, lignin sulfonate, humic acid in negative paste and the effects of them on negative plate performance were studied.

99. The effects of transitional metal ions on the oxiammonolysis of wheat straw alkaline lignin with hydroperoxide were studied.

100. High boiling solvent (HBS) lignin amine was prepared by Mannich reaction with dimethylamine. The adsorption of HBS lignin amine and bromelain was investigated.

101. The present results indicated that POD had participated in the lignification. However, the distribution of POD was not same as the regions of lignin deposition completely.

102. Lignin is a kind of important macromolecular organic material and only inferior to cellulose inside plant, with a content of 15%-30%.

103. The microwave irradiation ( MI ) process to extract lignin from straw had been developed.

104. The lignin structures and probabilities of reed and amur silver grass were studied and compared.

105. Lignin of rice husk high boiling point solvent ( HBS ) digesting process with aqueous solvent of ethanediol.

106. The bamboo lignin is rich in syringyl units[sentencedict.com/lignin.html], which is indicated by a high methoxyl content and respective bands in the IR spectrum.

107. Lignin has influences at different extents on mechanical properties, ageing property, thermostability and thermal degradation of plastics.

108. Lignin : Complex oxygen - containing organic compound, a mixture of polymers of poorly known structure.

109. The recovery process of lignin from the alkaline reed paper-pulping effluent black liquor by acidulation precipitation was studied.

110. The variation degree of PAL activity, lignin growmjiight-growth of each Alnus cremastogyne clones is consistent.

111. Lignin staining showed an increase in lignification in culms of the overexpressor lines.

112. Plant cell walls can be strengthened for extra support by addition of lignin (as in xylem and sclerenchyma)or extra cellulose(as in collenchyma).

113. The plant residue with more lignin has a higher humification coefficient. As the residue containing more N is more favorable to the formation of soil microaggregate.

114. The nutrient content of the straw is high. The crude proteincontent of the strow is 7.56%, and the gastricism factor of cellulose(lignin)islower.

115. Recent advances in lignin biodegradation of rice straw by Panus conchatus were attributed.

116. Corn stalk was an abundant and renewable resource and mainly consisted of cellulose , hemicellulose and lignin.

117. The Cinnamoyl CoA reductase (CCR) gene is involved in determining lignin content and composition in plant secondary cell walls and has been associated with wood strength characteristics in Eucalyptus.

118. Moreover, it was shown that degradation of lignin was promoted by veratryl alcohol added, no effect of veratryl alcohol on degradation of cellulose and hemicellulose was detected.

119. In this part, the presence of lignin in cooking liquor how to affect the viscosity, density and Hamaker constant have been studied.

120. After heating treatment, the relative content of lignin increased, while holocellulose and alpha-cellulose decreased of 4 years bamboo.
