Abstract: The present invention is related to a method to promote cell growth, comprising: (a) cloning one or more aspartase coding sequence into a vector to become a recombinant vector, wherein the recombinant vector including a promoter and one or more aspartase coding sequences manipulated to link and insert into the downstream of said promoter; (b) transforming the recombinant vector into host cells and producing recombinant host cells; and (c) culturing the host cells in culture medium and making the cells to express aspartase, then promoting said recombinant host cells growth. The aspartase can not only promote cell growth but also increase the amount of the target gene expression.

Abstract: The present invention relates a process for culturing isolates of Antrodia camphorata to provide a product useful in medical and nourishment fields. The present invention also relates to a novel isolate of Antrodia camphorata capable of growing in a suitable artificial medium, while exhibiting desired pharmacological activities, in particular anti-tumor activity. The utilization of potato dextrose broth and the synthetic medium containing fructose as major carbon source leads to a significant increase in the pharmacological activity of the cultures of A. camphorate.

Abstract: A grain sorting method and a device is provided which serves to continuously and quickly detect the appearance quality of the grains. The grain sorting device includes a feeding mechanism and a scattering mechanism where the grains are separately scattered over the surface of a conveying belt. The conveying belt serves to transfer the grains to a photographing section where they are photographed and inspected by an electric coupling device. Various parameters of the grains are calculated and the inspected results are compared with data stored in a computer. The grains are then sorted into different classifications and respectively collected by a discharging device.
Abstract: Green fluorescent protein (GFP) gene was transplanted into baculovirus. The baculovirus was used to infect pests of vegetable crops. Three to five days after infection, the infected insects were found to emit strong fluorescence when exposed to a portable UV light. Therefore the spreading of baculovirus infection and disease progression can be effectively detected in the field. In addition, the GFP reduced UV damage to the baculovirus. As a result, GFP can increase the retention time of the virus as a pesticide in the field.
