石油污染是造成海洋污染的一个重要因素,严重影响渔业,环境健康以及人类的生活。其中尤以多环芳烃的污染最为严重难于处理难于降解,是目前环境问题研究中的一个重要课题。本文的目的是研究渤海沉积物中微生物对芘胁迫的响应,将终浓度为600mg/L的芘加入到含有5g渤海底泥的锥形瓶中,分别取出10d,20d,30d,40d的样品进行分析,提取DNA,进行高通量测序。结果发现,随着时间的延长,芘的含量明显减少,渤
Objectives:Cyanobacterial blooms in freshwater lakes have become one of the most widespread environmental problems and threaten the quality,safety,ecological integrity and sustainability of water reso
Objective:Microcystis spp.is one of the most widespread poisonous cyanobacterial species.The water quality and natural scenery were damaged by the Microcystisbloom in Lake Taihu.In temperate and tropi
The prevailing view that the evolution of cells in a tumor is driven by Darwinian selection has never been rigorously tested.Because selection greatly affects the level of intra-tumor genetic diversit
As a member of Arecaceae,Coconut(Cocos nucifera)is cultivated in more than 80 countries across the world.The coconut plant,including its fruit,is a source for a variety of valuable industrial products
Coconut(Cocos nucifera L.),a member of the palm family(Arecaceae),is one of the most economically important crops in tropics as a source of food,drink,fuel,medicines and construction material.Based on
There is a common belief that some males are better than others for pollinating certain varieties in date palm.However,there is few studies in this field in Saudi Arabia.Therefore,identification and s

With the explosive growth of high-throughput sequencing data,there is an increasing number of biological databases that have been developed for managing different types of data and this number,without
Next-generation sequencing technologies have greatly promoted the genomic study of prokaryotes.However,highly fragmented assemblies due to short reads from NGS are still a limiting factor in gaining i
