核诱变(^(60)Co-γ射线)高产纤维素酶菌的选育及分子鉴定

Molecular identifi cation for high cellulase production of Actinomycetees by UV and ^(60)Co-γ ray

从湖南岳麓山枯枝腐木土壤层下取样,筛选出产纤维素酶较高的菌株A24,采用紫外与60Co-γ射线诱变获得的高产纤维素酶菌株系(Co-07)为研究对象,对菌株的16s rDNA进行扩增、测序,利用NCBI数据库进行Blast比对,经MEGA5.0软件构件系统发育树后可以确定为链霉菌属中的三泽链霉菌亚种。

The process of covariant conserved charge of gravitational theory, which is covariant under general coordinate and local Lorentz transformations, has been applied to many tetrad fields, which reproduce Kerr-Ads spacetime, to calculate their conserved charges. It is shown that this process gives an infinite value of the conserved charges for Kerr–Ads spacetime. Therefore, the method of “regularization through relocalization”, i.e., modification of the Lagrangian of the gravitational field through a total derivative, is used. This method gaves a finite and a consistent result of total energy and angular momentum for Kerr–Ads spacetime.
