ジャーナル フリーMethane fermentation can be utilized as a fuel gas producing process from solar energy because plant-body can become the raw material f or methane fermentation. The bacteria which cause methane fermentation can be grouped into methanogenic bacteria which produce methane and non-methanogenic bacteria which produce substrates f or methanogenic bacteria. The substrates f or methanogenic bacteria are hydrogen and carbon dioxide, acetate, f ormate, and methanol. Acetate is utilized only in the presence of hydrogen by some species of bacteria, and is utilized even in the absence of hydrogen by other species. The existence of bacteria which produce methane from propionate or n-butyrate is doubted. Some examples of symbiotic relation between methanogenic and non-methanogenic bacteria are known. Methane fermentation of algae, water hyacinth, arrowroot, giant kelp etc. has been studied in U.S.A. In Japan methane fermentation of urban wastes has been studied. Now we are needed to carried out not only macroscopic studies on a total system of waste water treatment processes, wastes treatment processes, and solar energy-utilizing processes but also microscopic studies on the phenomenon of methane fermentation itself.抄録全体を表示PDF形式でダウンロード (840K) -

ジャーナル フリーBiochemicalfuel cells, which are unique combination of biochemical and electrochemical reactions, have been developedfor the conversion of biomass to electric energy. The biochemicalfuel cells areclassified into an enzyme cell and a bacterial cell in which enzymes and microbial whole cells are utilized as catalyst, respectively. Abiosolar cell modeled on the photosynthetic process has been currently proposed. The principles and prospective aspects of these energy conversion systems are reviewed.抄録全体を表示PDF形式でダウンロード (1138K) -

ジャーナル フリーAs a result of decreasing supplies of f ossil hydrocarbons it has become recessary to reexamine other sources of raw materials f or possible conversion into hydro-carbons. In connection with the utilization of solar energy for renewable resources, the auther has been concerned with the lipid analysis of photosynthesizing plants such as rubber tree (Hevea brasiliensis), some dif ferent species of Euphorbia and other latex-bearing plants which grow naturally in tropical and temperate regions. The results have indicated that Euphorbia plants, e. g. E. tirucalli and E. lathyris contain a large amount of lipids such as triglycerides and steroidal triterpenes (about 1 to 2%w/w of the fresh plant). However, since Euphorbia plants have co-carcinogenic and toxic substances, e. g. diterpene esters, the industrial production of these oil might give rise to environmental problems such as air pollution.
It is well known that Eucalyptus plants (some 600 species) also produce amount terpeoidal hydrocarbons. The most fascinating Eucalyptus plants which contain a large of oils have been explored. As the result, E. radiata, which is one of good canditotal. dates was discovered in Australia. It consists of 4.2% volatile and 4.5% non-volatile in total. Namely, about 95l or 8.7% (w/w) of ether-acetone soluble oil is gotten from one ton of the fresh juvenile E. radiata. The utilization of residue which contains cellulose and lignins is also very important. The microbiological biomass conversion of the Eucalyptus residue should be studied.抄録全体を表示PDF形式でダウンロード (1833K) -

ジャーナル フリーThe national plan for alcohol fuels of sevral countries are introduced. Then author discusses costs of alcohol fuels from different crops and also energy balances through production of alcohol fuels.
The author considers the cronic oil crisis and the South-North problem as the twin brothers of the same economic and political origins. To solve these problems, the author insists to promote the parallel development in both rural and industrial sectors. From this point, alcohol fuels from energy farming will be one of the most hopeful projects. The author compares several crops f or the raw material and finally recomends sweet potato in the Asian region.抄録全体を表示PDF形式でダウンロード (1738K) -
