For further understanding the effect of the strain on K-bearing silicate mineral, an experiment with KO2 strain cultured in nitrogen-containing and nitrogen-free medium was conducted. By putting mineral powders into the medium and measuring the concentration of capsular polysaccharides, we concluded that the strain can accelerate the weathering rate of silicate minerals. The results showed that the polysaccharides secreted by the strain in the growth process could help the bacterial to adhere to the mineral surface effectively, and created the bacterium-mineral complex, which formed a mircro-enviorment avail the release of potassium. Another result was that there was higher level of Carbonic Anhydrase activity, which revealed that some exo-protein or enzyme produced by the bacterial had postive impact on the process of releasing potassium ion. We carried out the bacterial fermentation for larger scale production of the bacterial secretion, which was used to sperate, and identify the small molecules related to the mineral-bacterial interaction. After the analysis, it was found that the strain can produce many kinds of small molecules, such as 2-Hydroxybenzoic acid, 4-Hydroxyphenylacetic acid, methyl-4-hydroxybenzoate, etc.
分别将菌株接入含有不同矿粉的培养基中培养，检测其在有氮、无氮培养基中荚膜多糖含量的变化，并在以钾长石和黑云母为矿源的情况下，比较研究了菌株在有氮、无氮培养基中对矿物的风化能力，通过一系列的实验，证实胶质芽孢杆菌在生长过程中所分泌的粘稠胞外聚糖可帮助细菌有效黏附在矿物表面，形成细菌-矿物复合体，并改变及维持该复合体内部的微环境，有助于该菌的解钾作用，而且细菌分泌的胞外蛋白质在该菌对含钾硅酸盐矿物的解钾作用过程中发挥重要作用；将胶质芽孢杆菌接入以钾长石和黑云母为矿源的有氮、无氮培养基中培养，检测到该菌碳酸酐酶活性的变化，并进行批量发酵后小分子酸性分泌产物的提取、分离、纯化与鉴定等方面的研究，结果表明，该菌可产生2-羟基苯甲酸，4-羟基苯乙酸，4-羟基苯甲酸甲酯等小分子物质。

The results showed that elevated CO2 increased the R/S ratio and the dry mass of both coarse and fine roots, indicating that the seedlings under elevated CO2 allocated more biomass to their belowground part. Compared with control, elevated CO2 increased the contents of reducing sugar, sucrose, and total soluble sugar in coarse roots significantly, but had less effect on those in fine roots. Elevated CO2 increased the contents of starch and total non-structural carbohydrate both in coarse roots and in fine roots. Under elevated CO2, the carbon content in coarse and fine roots had an unsignificant increasing trend, while the nitrogen content decreased significantly, which resulted in an increase of C/N ratio.
结果表明：CO2浓度升高使红桦幼苗粗根和细根的干质量增加，同时根／冠值显著升高，表明CO2浓度升高使红桦幼苗生物量向根系的分配增加；与对照相比，粗根的还原糖、蔗糖和总可溶性糖含量显著增加，而在细根中没有显著变化；粗根、细根的淀粉和总的非结构性碳水化合物含量显著增加；CO2浓度升高下粗根和细根的碳含量有升高的趋势但未达到显著水平，同时氮含量降低，碳／氮值升高；氮的吸收量在粗根和细根中均无显著变化。

Finally, the pH value, lactic acid, water soluble carbohydrate, ammonia nitrogen and cellulose contents were determined for WH silage prepared under the suitable adding doses of lactobacillus and cellulase at day 1, 3, 5, 15, 25, 35 after ensilaging. The pH value decreased from 5.5 before ensiling to 4.3 on the 35th ensiling day, whereas the reverse change tendence was observed for lactic acid content. The cellulose content of silage was lower from 26.5%DM in raw material to 22.3%DM.

No evident regularity was found in the depth from 15 to 30 cm. There was an obvious accumulation of OM and TN in the top 30 cm of the fallowed soils, of which the accumulation of OM was faster than that of TN and there was more accumulation in no-tillage compared to tillage. Soils applied with inorganic and organic fertilizers had much more OM and TN at 0～5 cm and 5～15 cm depth than soils applied with only inorganic fertilizers and soils without fertilization. However, OM and TN in these treatments were less than that in fallow treatment. No significant differences in OM and TN contents were found between fertilization treatments. Only in the 5 cm of top soils, OM and TN of the soils treated with only inorganic fertilizers were more than that of CK.
长期休闲的土壤在整个耕层有明显的有机质和氮素累积，其中碳的累积快于氮的累积，免耕条件下比耕翻条件下累积量更大。0～5 cm和5～15 cm土层有机肥与无机肥配施的处理，其有机质和全氮质量分数均显著高于单施化肥处理和不施肥处理，但均低于休闲处理；15～30 cm土层各培肥处理则无明显差异；单施化肥的土壤有机质和全氮质量分数高于不施肥处理，但这种差异只在表层（0～5 cm）较显著。

The results show that though the strain is growing slower in the nitrogen-free medium than in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium. The capsular polysaccharides produced by the strain in the culture which contains different mineral powders will reach the highest content on the third or the fourth day in its growing period. The strain's capability of releasing potassium from k-feldspar and biotite in the nitrogen-containing medium is higher than that in the nitrogen-free medium because in the nitrogen-free medium, the strain and its production of glucoprotein are less than those in the nitrogen-containing medium.
结果表明，尽管该菌在无氮培养条件下的菌体数量远小于有氮培养条件，但无氮培养条件下所提取的细菌多糖多于在有氮条件下培养所提取的细菌多糖；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的无氮培养基中生长可形成大量多糖，采用丙酮法进行细菌培养液多糖提取，发现细菌培养的第3天所提多糖含量最高；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的有氮培养基中生长亦可形成较多的多糖，且在细菌培养的第4天所提多糖含量最高；胶质芽孢杆菌在有氮条件下对含钾矿物的释钾率高于在无氮条件下的释钾率，这可能与该菌在有氮条件下生长更快、可产生较多菌体细胞有关。
