Chitin deacetylase (CDA) catalyzes the conversion of chitin to chitosan by the deacetylation of N-acetyl-D-glucosamine residues. In this study  9 strains of bacteria with chitin deacetylase activity were isolated from canal mud samples from theXiangjiang River in Changsha  Hunan Province. Of these 9 strains  the Z7 strain had the highest chitin deacetylase activity  as determined by enzyme assay screening. Based on its culture  morphological  physiological characteristics and molecular identification  strain Z7 was identified as Bacillus amyloliquefaciens. Yeast extract at a concentration of 1.0% was an ideal nitrogen source for production of CDA (16.78 Eu/ml). Starch at 2% functioned best as the major carbon source for optimum production of CDA (17.84 Eu/ml). Magnesium sulfate at a concentration of 0.04% was an ideal inorganic salt for CDA production (17.45 Eu/ml). Ideal pH and temperature for optimum production of CDA by this strain were pH 6 and 37˚C.

It is important to study the interaction effect between laser and photoelectric detector. In most of the laser detecting systems  laser must irradiate the photoelectric detector. The detector will be saturated or damaged easily if the fluence of the laser is higher than the saturation threshold of the detector. Now  many photoelectric detectors are used in space. To achieve their interaction  "Cat's eye" effect is applied to find and locate the remote aerial detector by laser. The possibility and mechanism of disturbance to remote aerial detector induced by laser are analyzed  and the factors of influence are also analyzed. The fluence of laser on the photoactive area of remote aerial detector is estimated. With two samples of CCD and TV tracking system  the mechanism of soft damage to CCD and TV tracking system induced by laser are introduced. The saturation of CCD and crosstalk of CCD are the main reasons of disturbance. When the tracking system is used in wave-door tracking mode  it will lose its tracking target if the saturation or crosstalk of CCD can enter into wave-door. At last  the influence to disturbance induced by atmosphere effect is also analyzed.
