(June 8) The 54th Hiroshima University Biomass Evening Seminar (The 15th Hiroshima University ACE Seminar)

Biomass Project Research Center, Hiroshima University, and HOSTY Association are co-organizing the Hiroshima University Biomass Evening Seminar. This seminar covers topics from the fundamentals of biomass to the latest information so that it can contribute the activities on biomass in this district. The 54th seminar will be held as follows. Please join.

“Elucidation of anaerobic degradation mechanism of hardly degradable biomasses by microbial symbiosis and its application to production of useful materials”

Alginate and chitin are promising renewable resources because they are abundant on the Earth. However, alginate and chitin can not be utilized by industrially utilized microorganisms such as Esherichia coli, Yeast and so on. Recently, we have found that the microbial consortia in the environment can easily utilize hardly degradable biomass.
In this seminar, we will introduce the degradation mechanism of alginate by bacterial symbiosis and its application to useful materials.

“Decomposition behavior of DNA in subcritical and supercritical water”

Phosphorus is used for fertilizer to grow plants and its form is inorganic phosphorus. Recently, phosphorus recovery from sewage sludge have been researched and hydrothermal treatment is proposed as one of the method. DNA is one of the organic phosphorus contained in sewage sludge and we determined the behavior in this study. At this time, the experiment was conducted by changing the temperature from 300℃ to 450℃. Total phosphorus yield and Inorganic phosphorus yield decreased with the increase of reaction temperature or residence time under supercritical condition.

“In situ Mass spectrometry of hydrothermal reaction products”

Recently, with rising prices for petroleum and concern for global warming due to the use of fossil fuels the development of renewable fuel source continues to attract a lot of attention. The technology for conversion of biomass resources into fuels and chemicals are necessary. To determination and manipulation of the primary product during the hydrothermal process of macroalgae. Therefore, the aims of this research to develop and design the rapid analysis of sugar production under hydrothermal pretreatment conditions via in situ mass spectroscopic method. The products of glucose during hydrothermal; pretreatment under various temperatures (140-220℃) have been investigated. Moreover, the results from in situ analysis, and commercial HPLC were compared.

We will hold the discussion meeting from 18:00 (800 JPY needed).  Join this meeting, too if you are available.
