Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the examples.

[0011] 1. Screening and physical and chemical properties of Nannochloropsis HH-1 (Nannochloropsis sp.)

[0012] 1. Screening of Nannochloropsis HH-1 (Nannochloropsis sp.)

[0013] The seawater samples taken from the sewage outfall of Shilaoren Beach in Qingdao were picked out under an inverted microscope with a capillary to pick out a single algal cell, and then cultured in a 96-well plate. The medium used for the culture was f / 2 medium (Guillard and Ryther 1962, Guillard 1975). Add the following components to each L of filter-sterilized seawater for f / 2 medium:

Abstract

The invention relates to oil-enriched marine microalga and application thereof. The oil-enriched marine microalga is Nannochloropsis gaditana HH-1 with preservation number of CCTCC (China Center for Type CultureCollection) NO: M2012091. The oil-enriched marine microalga with low pH resistance screened by the invention can normally grow in an environment with pH of 4.5, and the grease content can be 35 percent, so that a novel strain is provided to biodiesel development by coupling power plant exhaust gas. The oil-enriched marine microalga provided by the invention has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of marine microalgae screening application, in particular to an oil-rich marine microalgae and its application, in particular to a marine Nannochloropsis sp.HH-1 and its coupling with power plant exhaust gas for biodiesel development Applications. Background technique [0002] In recent years, due to the sharp increase in global consumption of fossil fuels and the reduction of petrochemical reserves, a worldwide energy crisis has been caused, coupled with the environmental problems caused by the emission of carbon dioxide from the combustion of fossil fuels. Therefore, it is necessary to look for a cheap green renewable energy It has become a scientific and social issue of widespread concern to governments and people all over the world. Biomass energy, as an important clean energy, ranks first in the current renewable energy in terms of energy reserves and consumption, and provides an effective way for us t...
