荀子“性恶”再探析

“性恶”是荀子的一个重要思想,以往学界大都从“恶”的角度出发来考察和分析荀子之“性恶”,本文则另辟蹊径,从“性”的角度出发来考察和分析荀子之“性恶”,通过对“‘性’训作什么？”、“‘性’指什么？”以及“‘性’怎么样？”这三个问题的回答揭示出荀子“性恶”的实质乃是性“离朴”而恶和性“纵欲”而恶,同时更指出了荀子的“性恶”并不是纯粹的“恶”,而是“性恶”中本具自觉向善的倾向和向善的能力,也就是说,荀子的“性恶”是一种积极的“恶”而不是一种消极的“恶”,正是基于此,所以荀子才说“涂（途）之人可以为禹”。

2,3-Dihydroxybiphenyl dioxygenase gene was first discovered in Arthrobacter sp. strain PJ3

Bacterium strain PJ3,isolated from wastewater and identified as Arthrobacter sp. bacterium based on its 16S rDNA gene,could use carbazole as the sole carbon,nitrogen and energy source. The genomic library of strain PJ3 was constructed and a positive clone JM109(pUCW402) was screened out for the expression of dioxygenase by the ability to form yellow ring-fission product. A 2,3-dihydroxybiphenyl dioxygenase(23DHBD) gene of 933 bp was found in the 3360 bp exogenous fragment of pUCW402 by GenSCAN software and BLAST analysis. The phylogenetic analysis showed that 23DHBD from strain PJ3 formed a deep branch separate from a cluster containing most known 23DHBD in GenBank. Southern hybridization confirmed for the first time that the 23DHBD gene was from the genomic DNA of Arthrobacter sp. PJ3. In order to test the gene function,recombinant bacterium BL21(pETW-8) was constructed to express 23DHBD. The expression level in BL21(pETW-8) was highest compared with the recombinant bacteria JM109(pUCW402) and strain PJ3. We observed that 23DHBD was not absolute specific. The enzyme activity was higher with 2,3-dihydroxybiphenyl as a substrate than with catechol. The substrate specificity assay suggested that 23DHBD was essential for cleavage of bi-cyclic aromatic compounds during the course of aromatic compound biodegradation in Arthrobacter sp. strain PJ3.
