A Variable-tilt Fermentation Rack for Screening Organisms in Microfuge Tubes
نویسنده
چکیده
We designed a variable-tilt microfuge fermentation rack to screen liquid cultures of wild and mutant yeasts for ethanol production. The rack design allows for the evaluation of up to 40 cultures in the space normally required for three 125 mL Erlenmeyer flasks. Microfuge tubes containing 1.0 mL of inoculated medium were placed in the rack and incubated with shaking. This technique gave reproducible rates of ethanol formation in relation to sugar uptake.

Cardaria draba is an important, troublesome weed in the sustainable production of wheat. Inthe first step of this study, 100 actinomycete isolates were purified from soil samples collectedfrom the rhizosphere and phyllosphere of plants in different provinces of Iran. All isolates weresubjected to primary screening by assaying the fermentation broth of the sterile surfaces of C.draba leaves. Con...

SUNITA SINGH, m.b., b.s. (Punjab) From the Brigade Laboratory, Allahabad Instead of the ordinary rectangular rack, a circular rotary rack has been used by us. The experimental tubes are rotated alongside the control tubes. The light comes from below after being reflected from a black surface. The readings are very clear and can be quickly made without disturbing the tubes. The rack consists of ...
متن کاملRetrieval–travel-time model for free-fall-flow-rack automated storage and retrieval system
Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...

Described in this report is a method for the fabrication of a versatile , inexpensive rack for microcentrifuge tubes that offers distinct advantages over conventional plastic racks. In addition to holding a larger number of samples than conventional plastic racks, this rack can also support samples in an ice slurry or shallow water bath. Since these racks take about five minutes to make and cos...
