Knowledge of,and Attitudes Towards Health-related Biotechnology Applications Amongst Australian Year 10 High School Students

Modern biotechnology has a large and rapidly increasing impact on society. New advances in genetics, stem cells and other areas hold great potential for human health but also presenting socioscientific issues that commonly divide public opinion. While knowledge is necessary to develop informed opinions about biotechnology, they may also be influenced by polarized discourse and fiction in the media. Here, we examined prior knowledge about and attitudes towards health-related biotechnological applications in Year 10 high school students from Western Australia using online questionnaires. The impact of teaching on students’ understanding was tested by repeating the questionnaire after a lesson. Finally, students’ argumentation skills were examined by recording responses to statements about biotechnological applications. We found that, prior to instruction, most students exhibited a reasonable understanding of biotechnology. There was little evidence for alternative conceptions, and instruction led to a diversification in understanding. Attitudes towards biotechnology were generally positive but varied. Despite interest in biotechnological issues, argument for positions was generally cognitive-affective in nature. Consequently, biotechnology is a relevant topic for science education, and presents excellent opportunities to build on pre-existing knowledge. Rather than expanding students’ knowledge, our results suggest educators should focus on deepening existing understanding and strengthening argumentation skills.

Microbial Resource Management: The Road To Go for Environmental Biotechnology

The breakthroughs in microbiology have allowed us to come to terms with the microbial resources present in culture collections and in natural environments. The challenge at present is to manage these microbial resources, particularly when one deals with open systems where the dynamics of microbial ecology are predominant. Hence, to properly address the aspects of Microbial Resource Management (MRM), one needs to handle the questions of who is there, who is doing what with whom and how can one adjust, control and/or steer these mixed cultures and communities. It is argued that microbial ecologists and environmental microbiologists need to address a new mind‐set. The Beijerinck axioma that all microorganisms are everywhere should not be presumed to be generally valid. The Darwin based niche assembly concept needs to be supplemented with the neutral theory of Hubbell. The Pareto 80/20 principle is also applicable to the macro‐economies of microbial communities. Finally, the concept of a “stable” microbial community should be replaced by that of a cooperative community continuum. Overall, MRM is at the basis of a number of new developments in domains such as environmental safety and health, renewable energy production, closing environmental cycles and providing new materials. Specific examples such as, for example, pro‐active immuno‐stimulation by means of drinking water, electro‐microbiology, decreasing global warming by implementation of methanotrophs and generation of nano‐biocatalysts are discussed.     

蓖麻生物工程研究进展

蓖麻是一种高蓄能植物和工业原料植物,具有很大的开发利用价值。本文从组织培养和遗传转化两个方面并结合本实验室的工作综述了蓖麻生物工程研究的最新进展。在蓖麻组织培养方面,不同的外植体中以成熟种子的胚轴最适宜,而在不同激素中以TDZ诱导丛生芽的效率最高,并以此为基础建立了蓖麻离体再生体系。在遗传转化方面,不同的转化方法中以农杆菌介导法最适合蓖麻转化。蓖麻胚轴对卡那霉素不敏感,潮霉素是蓖麻转化的适宜筛选剂。文中指出了蓖麻生物工程研究中存在的问题,并对应用生物技术培育蓖麻新品种和促进蓖麻生产的可能性进行了讨论。
