18 strains of Bacillus mucilaginosus were sampled from Poyang Lake area of Jiangxi province in China . Morphology and physio-biochemical characteristics and desilication ability on bauxite were studied. The results showed that all strains are rods and produced spores from elliptical to circular， while strains of P8、P11、P15 are short rod. Gram reaction of 18 strains are negative.The strains can use nitrites and ammonium salt as nitrogen source, and survived in the nitrogen free medium. P4、P3 showed strong desilication ability, compared to blank control the content of soluble SiO2 increased to 4.57、4.13 times respectively; P2、 P7、P9 could tolerate 4% NaCl and were growing well at the temperature ranging from 25~35 °C.

Ten strains of silicate bacteria were screened from three bauxite samples in Jiangxi Province and Henan Province in China. The ten strains were determined as B. mucilaginosus according to the results of physiological and biochemical characteristics and desilicon ability. Bioleaching tests showed that the ten strains all can decompose bauxite ore and release silicon from bauxite, but had a large difference of desilicon ability among them.

Potassium Solubilizing Bacteria

29 strains of KSB(potassium solubilizing bacteria) were sampled from red soil of Poyang Lake area of Jiangxi province in China. Potassium solubilizing screening and temperature and pH tolerate experiments were conducted in red soil medium: 5 strains include K10, K12, K14, K16,K29 with better potassium solubilizing ability were screened. Further study shows K16 performs better at low temperature of 15-25°C, while K12 keeps active at a temperature of 40°C, All strains show biggest potassium solubilizing ability at pH6.5 except K10 at pH5.5. And K10 stays active at a low pH of 3.5-5.5.

Poyang Lake Area

Poyang Lake is located in the northern part of Jiangxi Province, is one of the important Yangtze River flood storage lakes. Use Mann-Kendall test the trends and mutation of the Poyang Lake area rainfall time series, and use singular spectrum analysis (SSA) method to analyze the time series of periodic oscillation characteristics. The results showed that, the Poyang Lake area rainfall time series no significant upward or downward trend, there are quasi 4-5 years, 8-11 years, 20-year periodicity.
