RESUMEN
A new style of tofu coagulated through the fermentation of Lactobacillus plantarum SJ-L-1 was produced. L. plantarum SJ-L-1 with a high growth rate and excellent acid production ability was isolated and identified from naturally fermented soy yellow whey. The gene annotation indicated the potential outstanding isoflavone conversion capacity of L. plantarum SJ-L-1. Furthermore, fermentation tofu was prepared using L. plantarum SJ-L-1 and Lactobacillus rhamnosus 1-16 as the starter microbiota. Compared to traditional MgCl2 tofu and fermented soy whey tofu, SJ-L-1 tofu exhibited a slight increase in hardness and better structure uniformity. SJ-L-1 tofu also possessed the highest levels of total isoflavone content (76.33 µg/g) and volatile compounds (561.54 µg/kg) among the four styles of tofu. This research indicated that this new type of tofu coagulated through a combination of heat and fermentation of L. plantarum SJ-L-1 represents a promising candidate for future functional foods.
RESUMEN
With the development of science and technology, new medical equipments is toward the direction of intelligent and portable. In order to assist medical personnel to patients with blood, developing from previous devices, a new kind of vein locating projection instrument based on two-dimensional scanning mirror is put forward. It can scan and project vein image using a scanning mirror. The related algorithm is also be improved, make vein scan projection more practical. The system finally set up can perform well in vein scan projection.

An acclimated activated sludge was examined for its ability to degrade meta-fluorophenol as sole carbon source in aerobic batch cultures. The mechanism study revealed that the initial step in the aerobic biodegradation of meta-fluorophenol was their transformation to fluorocatechol. Following transformation of the fluorophenol to fluorocatechol, ring cleavage by catechol 1,2-dioxygenases proceeded via an ortho-cleavage pathway, then defluorination occurred.
