9618728 Fisk Substantial evidence supports the view that microorganisms can affect geochemical change in the atmosphere, hydrosphere and sediments. Little is known , however, about microbial influence on chemical change in the lithosphere. Recently, new evidence has indicated that the alteration of basalts may be affected by the presence of microbial life which influence the rate of alteration and the composition of products. The objective of this award is to test for microbes in basalts and to determine the distribution and identity of these communities. Initially basalts from existing collections will be screened for carbon, nucleic acids, and textures that have been reported as evidence of endolithic microorganisms. DNA or RNA will then be extracted to further identify the organisms present. ***

9618728菲斯克大量证据支持微生物可以影响大气、水圈和沉积物中的地球化学变化的观点。然而，人们对微生物对岩石圈化学变化的影响知之甚少。最近，新的证据表明，玄武岩的蚀变可能受到微生物生命的影响，微生物生命的存在影响蚀变速率和产物的组成。 该奖项的目的是测试玄武岩中的微生物，并确定这些群落的分布和身份。 最初从现有的玄武岩收藏将筛选碳，核酸和纹理已被报告为证据的石器时代微生物。然后将提取DNA或RNA以进一步鉴定存在的生物体。 ***
