Polylactate (PLA) is synthesized as a representative bio-based polyester by the chemo-bio process on the basis of metal catalyst-mediated chemical polymerization of lactate (LA) supplied by microbial fermentation. To establish the one-step microbial process for synthesis of LA-based polyesters, we explored whether polyhydroxyalkanoate (PHA) synthase would(More)
In this paper, we presented a novel process involving activated carbon (AC) as an adsorbent for lactic acid fermentation, separation and oligomerization. It was found that pH has a significant effect on the adsorption of lactic acid on AC. The use of AC for in situ removal of lactic acid successfully decreased the inhibitory effect of lactic acid, resulting(More)
In this study, component analysis of a novel biodiesel-producing alga, Pseudochoricystis ellipsoidea, was performed. The component analysis results indicated that proteins and amino acids are abundant in P. ellipsoidea while the sugar content is relatively low. Rather than its use as a carbon source, the use of the algal biomass residue after oil extraction(More)
Black rot of sweet potato caused by pathogenic fungus Ceratocystis fimbriata severely deteriorates both growth of plants and post-harvest storage. Antimicrobial peptides from various organisms have broad range activities of killing bacteria, mycobacteria, and fungi. Plant thionin peptide exhibited anti-fungal activity against C. fimbriata. A gene for barley(More)
Liver fibrosis can progress to cirrhosis and result in serious complications of liver disease. The pathogenesis of liver fibrosis involves the activation of hepatic stellate cells (HSCs), the underlying mechanisms of which are not fully known. Emerging evidence suggests that the classic histone deacetylases play a role in liver fibrosis, but the role of(More)
Abstract—A purpose of this study is analyzing a human’s controller to understand a mechanism of skill acquation processes for riding a unicycle. In order to analyze the controller, inputs which an operator gives to the unicycle and states of the unicycle are measured and a human-unicycle model as same as the experiment is derived. A weighting matrix to the(More)
UNLABELLED PREMISE OF THE STUDY Nuclear microsatellite primers were developed to analyze the clonal diversity and population genetic structure of the endemic polyploid herb Callianthemum miyabeanum. • METHODS AND RESULTS Using a protocol for constructing microsatellite-enriched libraries, 15 primer sets were developed for use in C. miyabeanum. The(More)
Adiponectin is an adipose tissue-derived hormone. It is a key hormone that is responsible for insulin sensitization, and its circulating level is inversely associated with abdominal obesity. Recent studies have shown that a reduced plasma adiponectin level is significantly correlated with the risk of various kinds of cancers. Adiponectin may influence the(More)
This paper proposes a method for detecting two or more straight lines from an edge image in a similar way of Hough transform. The method consists of labeling of each edge point to presumed straight lines and RANSAC algorithm to evaluate each label. The Genetic Algorithm (GA), an efficient combinatorial optimization algorithm, is used for the labeling(More)
