A SHAKING DEVICE FOR LIQUID CULTURES

Journal of Applied Bacteriology, 1957
SUMMARY: Details are given for the construction of a reciprocating shaking device for liquid cultures. Up to 36 litres can be shaken at one time. The machine is compact, the base being only 28 in. square.

Enhanced retroviral transduction of 293 cells cultured on liquid-liquid interfaces

Biotechnology and Bioengineering, 2000
In clinical research, retrovirus-mediated gene therapy is one of the most commonly used methods to deliver and express the gene of interest due its ability to allow for stable gene integration into the chromosomes of target cells. To elevate the efficiency of viral transduction, several restrictions, such as low virus-cell encounters and the necessity ...

Microbial transformation and sorption of anthracene in liquid culture

Bioprocess and Biosystems Engineering, 2012
Armillaria sp. F022, a white-rot fungus isolated from decayed wood in tropical rain forest was used to biodegrade anthracene in cultured medium. The percentage of anthracene removal by Armillaria sp. F022 reached 13 % after 7 days and at the end of the experiment, anthracene removal level was at 87 %.

The Growth of Bone Marrow Cells in Liquid Culture

British Journal of Haematology, 1972
Summary. Liquid suspension cultures of mouse bone marrow cells at high and low density were prepared in supplemented Eagle's medium containing 10% of a partially purified extract of mouse embryos and pregnant mouse uterus (PMU). In the low cell density cultures the number of cells decreased for 2 days; by 4 days the agar colony‐forming cells (agar CFC)

Liquid nitrogen storage of cultured T lymphocytes

Journal of Immunological Methods, 1985
The conditions required for storing and recovering IL-2-dependent T cell clones from liquid nitrogen were investigated. For maximum cell recovery, cultured T lymphocytes were precooled at 4 degrees C for 15 min in medium containing 10% DMSO and 20% FCS before storage in liquid nitrogen.

Liquid Modernity and Cultural Analysis

Theory, Culture & Society, 2007
This extended introductory article sets the scene for consideration of liquid modernity and Bauman’s recent work in general. His ideas are placed against Pollock’s concept of the ‘trans-disciplinary’. The ramifications of Bauman’s work for cultural analysis are discussed, particularly his ideas about migration, tourism, borders and the impact of global

Preservation of Tissue Culture Cells with Liquid Nitrogen

Nature, 1962
FOR prolonged storage of biological materials it is generally considered that temperatures of −100° C. or lower are necessary1, and as thermodynamic changes have been demonstrated in mixtures of glycerol and Earle's solution in this temperature region2 and in ice at −130° C.3 it is preferable to use a lower storage temperature such as is provided by ...

Continuous liquid culture of the fungus Ophiostoma multiannulatum

Experimental Cell Research, 1953
Abstract A method is described by which it is possible to maintain a fungus under conditions of constant and continuous growth. By altering the rate at which fresh nutrient is added to the culture, the growth rate of the organism can be controlled.

Liquid culture of Diplodia maydis.

Microbios, 1980
Diplodia maydis, a Zea mays L. stalk rot causing fungus, was grown in Czapek-Dox broth and modifications of Fries liquid media using combinations of 1% cellulose, 1% sucrose and ammonium or nitrate-nitrogen. Conditions are defined to yield consistently maximum mycelial dry weight in two days in contrast to the usually reported five-day incubation ...

Evaluation of liquid and lyophilized preservatives for urine culture

Journal of Clinical Microbiology, 1983
Culture results of urine specimens transported conventionally (sterile cup) and in a commercial liquid or an investigational lyophilized preservative were compared in a hospital that experiences substantial delays in specimen transport to the laboratory (greater than 40% of specimens received after a delay of greater than or equal to 2 h).
