Heterotrophic bacterial diversity in aquatic microbial mat communities from Antarctica

最新版本 由 SCAR - Microbial Antarctic Resource System 發佈於 Jan 16, 2020 SCAR - Microbial Antarctic Resource System

This dataset describes heterotrophic bacteria that were isolated from five aquatic microbial mat samples from different locations in continental Antarctica and the Antarctic Peninsula.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 9 records. 1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

  • Event (核心)
    9
  • Occurrence 
    504

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

取樣方法

Microbial mat samples were collected aseptically using a sterile spatula, and were kept frozen continuously after collection until processing in the laboratory.

研究範圍 Bacterial strain isolated from five aquatic microbial mat samples from different locations in continental Antarctica and the Antarctic Peninsula, sampled between 2003 and 2007.

方法步驟描述:

  1. One gram of sample was aseptically weighed and homogenized in 9 ml sterile cold (4°C) physiological saline (0.86% NaCl) using a vortex. Tenfold dilution series (kept at 4°C) were plated on four different media (Marine agar 2216 (MA) (BD DifcoTM), R2A (BD DifcoTM), ten times diluted R2A (R2A/10), and PYGV (Pepton-Yeast-Glucose-Vitamin) medium (DSMZ medium 621)) and incubated at 20°C, 15°C and 4°C. R2A (Difco) contains pyruvate, starch and dextrose as C sources and yeast extract, peptone and casaminoacids as N and C sources and PYGV (DSMZ medium 621) contains peptone, yeast extract and glucose as C and/or N sources and additional vitamins and minerals. Both are considered oligotrophic media because the amounts of these components are at least two to ten times lower than in more general media such as nutrient broth. In addition to regular physiological saline (PS) dilution series, sea water (SW) dilutions were used for the LA3 and WO10 samples which originated from lakes close to the ocean and had elevated conductivity values.
