especially, adding fungal elicitor, anamorph of Exobasidium sp. HXa during the process of culture can improve the content of Monacolin K, 1330.4 μg/ml in liquid fermentation and 34.99mg/g in solid fermentation more than original strain 65.4 μ g/ml and 2.48mg/g to 20 times and 17 times , separately.
The optimal condition for enzyme performance was pH 4.2, temperature 50℃, when commerical pectin (Sigma) as a substrate. Thermostability of solid state is better than that of liquid state.
Compared to liquid state fermentation,Solid state fermentation(SSF)has many advantages such as high production and low cost,but SSF has not been used widely so far,because the bioreactor of SSF is relatively distinctive.
In this paper, a liquid paraffin as oil-phase is introduced into the system which is called twoliquid phase fermentation system. The yield of penicillin is enhanced by 0. 2 to 0.5 times at two percent oil fraction. The theoretical explantion for this fact is given based upon the experimental data measure for volumtric oxygen transfer coefficients (K_La) and on physical and chemical properties of both oil and aqueous phases.
especially, adding fungal elicitor, anamorph of Exobasidium sp. HXa during the process of culture can improve the content of Monacolin K, 1330.4 μg/ml in liquid fermentation and 34.99mg/g in solid fermentation more than original strain 65.4 μ g/ml and 2.48mg/g to 20 times and 17 times , separately.

A brief summary of the theoretical background of QSRR is followed by presentation of reversed-phase high performance liquid chromatographic (RP-HPLC) separation theories of applications to the reported QSRR.
Two new trichothecenes, Roridin P and Isororidin P, and two known trichothecenes, Verrucarin A and Verrucarin J, were isolated from liquid cultures of Myrothecium roridum Tale ex Fr.
A sensitive high-performance liquid chromatography (HPLC) method was established for the determination of concentration of 5-FU-1-acetic acid in the gastrointestinal contents and plasma of rats.
This article demonstrates the use of a linear programming model to achieve an optimal allocation of liquid funds among various currencies in different countries.
It is found that the temperature coefficient of the SAXS intensity (phonon component) for boron oxide changes at the temperature of the transition from a supercooled liquid state to a solid noncrystalline state.
The change in the slope is associated with the change in the temperature coefficients of the isothermal compressibility upon transition from a liquid state to a supercooled liquid state.
The temperatures of the glass transition and the transition from the supercooled liquid state to the noncrystalline solid state are determined from the temperature dependences of the SAXS intensity.
Changes in volume occurring during transition from the solid to the liquid state are estimated.
For the liquid state, this is unimportant; however, for the solid crystalline state, the situation changes significantly.
Compound 3 exhibited the enchased texture of a smectic liquid crystal from 209.4°C to 219.5°C on heating, while 2 exhibited a liquid crystalline phase from 87.4 to 83.2°C on cooling.
A liquid-solid coupled system equation of the micropump is presented.
Recently, it was realized that using a liquid metal or its alloys with a low melting point as coolant could significantly lower the chip temperature.
Some new advancement in making a liquid metal cooling device will be discussed.
The strain formed extracellular phenol oxidases during surface growth on a liquid medium in the presence of guayacol and copper sulfate, as well as during submerged cultivation in liquid medium containing wheat bran and sugar beet pulp.

No decline or degeneration of the strain's performance was observed after 20 qenerations of continuous culture.Here we describe in detail about the strain's isolating methods as well as its form and culture character. Hexanoic acid bacteria has been widely applied in the production of liquor by liquid method and fine quality white spirit was strong aroma. Also it plays a leading vole to improve ethyl hexanoate content in the finished product.
