Haa1 is a transcriptional activator required for Saccharomyces cerevisiae adaptation to weak acids. Here we show that the constitutive HAA1-overexpressing strain acquired a higher level of acetic acid tolerance. Under conditions of acetic acid stress, the intracellular level of acetic acid was significantly lower in HAA1-overexpressing cells than in the(More)
Fungi play a crucial role in the decomposition of lignin in fallen leaves but few studies have examined the functional roles of ligninolytic fungi associated with the decomposition of fallen leaves on tropical forest soils. This study examined fungal populations responsible for lignin decomposition in Castanopsis sieboldii leaves in a subtropical evergreen(More)
We have fabricated two-terminal mechanical stacked chalcopyrite-based tandem devices to identify the technical issues required to achieve high performance solar cells in the near future. A tandem device with a Ag(ln<sub>0.2</sub>Ga<sub>0.8</sub>)Se<sub>2</sub> (AIGS) top cell and a Cu(ln,Ga)Se<sub>2</sub> (CIGS) bottom cell showed an open-circuit-voltage(More)
Sustained release diltiazem hydrochloride (DIL) formulation is widely used over 110 countries worldwide, and is among the drugs recommended as a first-line therapy in the major guidelines for the management of hypertension. In search for a most suitable controlled release formulation of DIL, we investigated poly (2-hydroxyethyl methacrylate) matrix (pHEMA(More)
