Successful adaptation/acclimatization to low temperatures in micro-algae is usually connected with production of specific biotechnologically important compounds. In this study, we evaluated the growth characteristics in a micro-scale mass cultivation of the Antarctic soil green alga Chlorella mirabilis under different nitrogen and carbon sources followed by analyses of fatty acid contents. The ...

When building soil organic matter (SOM) contents in agricultural production systems, stabilization of both pre-existing as well as added C is important. A laboratory mineralization experiment was conducted over 374 days to evaluate the effect of pre-existing SOM on soil C mineralization after addition of organic matter (OM) using sugar cane. The SOM gradient used here stretched from 21 to 106 g...

Fungi form the biggest microbial biomass and are key drivers of hydrocarbon biodegradation. We here describe standard cultivation methods for fungi that use hydrocarbons either as sole carbon and energy source or co-metabolically degrade them. The methods include both liquid (Protocols 1 and 2) and solid-state cultivation approaches (Protocol 3) as well as a versatile protocol to monitor fungal...

A strain of Spirochoeta refringens has been obtained in pure culture, and its morphological and cultural characteristics have been studied. The strain possessed no pathogenicity for rabbits or monkeys. It probably belongs to the genus Treponema, but it is easily differentiated from Treponema pallidum, Treponema microdentium, and Treponema macrodentium. Its relation to Spirochoeta balanitidis an...

The purpose of this paper is to evaluate economic benefits associated with agricultural landscape-cultivating services provided as an input on behalf of the tourism sector in Austria. Applying the Contingent Valuation Method (CVM) 4600 tourists spending vacations in Austria were asked about their willingness to pay for these services in the summer of 1991. The mean and median was 9.20 ATS and 3...

Cell-based therapies have generated great interest in the scientific and medical communities, and stem cells in particular are very appealing for regenerative medicine, drug screening and other biomedical applications. These unspecialized cells have unlimited self-renewal capacity and the remarkable ability to produce mature cells with specialized functions, such as blood cells, nerve cells or ...
