土法造纸木素降解之探索Ⅲ.嫩毛竹自然发酵过程中的细菌分离鉴定与嫩竹软化菌的筛选

试验证实,嫩毛竹自然发酵过程中的微生物主要是细菌。分离出并纯化了１００株细菌,其中６０株是芽胞杆菌。将分离出的１００株细菌分别接入石灰预处理过的嫩竹,从中筛选出能使嫩竹进一步软化的菌株３株,也均为芽胞杆菌。对这６０株芽胞杆菌进行了形态学及其生理生化特征的鉴定,按Ｐｒｉｅｓｔ氏等（１９８８年）的数值分类系统分类到组,将３株（３０８,３０９,３１０）对嫩竹软化有明显作用的芽胞杆菌的１株（３０８）鉴定到种,认为是短小芽胞杆菌（Ｂ．ｐｕｍｉｌｕｓ）。另外４０株非芽胞杆菌参阅《伯杰氏系统细菌学手册》第１卷和第２卷,鉴定到科或属,有微球菌、葡萄球菌、李氏杆菌、不动杆菌、肠杆菌科等。

Origin of immature sulfur-rich oil in Jianghan oil field

Chemical structure of immature sulfur-rich kerogen and composition of immature sulfur-rich crude oil in Jianghun oil field have been studied. In molecular level, crude oil differs from thermolysed and chemolysed products of kerogen but does resemble the bitumen in immature sulfur-rich source rock. Therefore, immature sulfur-rich oil may be derived from the expelling of bitumen rather than from thermal cracking of kerogen.     

Carbon isotope anomaly in marbles associated with eclogites from the Dabie Mountains

This is a report of carbon isotope anomaly in marbles associated with the UHP eclogites from the Dabie Mountains. The results place constraints on the degree of crust-mantle interaction during the UHP metamorphism.     

Molecular cloning and nucleotide sequence of classical swine fever virus strain Shimen

According to the previously published CSFV sequences, 18 paris of partially overlapping primers which span the entire genome of CSFV strain Shimen were designed and synthesized. Each cDNA fragment of strain Shimen was amplified by RT-PCR method from the anticoagulant blood of strain Shimen infected pig. The PCR fragments were cloned into pGEM-T vector respectively and sequenced. The results show that we have obtained the nucleotide sequence of strain Shimen. The viral RNA consists of 12 297 nucleotides including noncoding regions of 373 and 227 bases at the 5′ and 3′ end, respectively, and a single large open reading frame spanning 11 697 nucleotides in the middle, which encodes an amino acid sequence of 3 989 residues with a calculated molecular weight of 437.6×10³. The precisely sequencing of 5′ and 3′ termini is undertaking. Supported by the National Pandeng Project Huang Qianhua: born in 1968. Graduate student
