important cut flowers in tropical and sub tropical areas of the world and has the seventh rate of production between all cut flowers of Iran. In order to investigate different effects of storage temperatures (8 weeks at 4 °C, 4 weeks at 4 °C + 4 weeks at 20 °C, 8 weeks at 12 °C, 4 weeks at 12 °C+ 4 weeks at 20 °C and 8 week at 20 °C) and different concentrations of gibberellic acid (0, 150 and ...

Crude wild pear lipoxygenase (LOX) from ripe Kurdistan wild pears was used in this study. Extracted crude LOX was assayed spectrophotometrically for raw, ripe wild pear lipoxygenase and after 7-day storage. The effects of different buffers and pHs, substrate preparations, temperature, inhibitors and metal ions on LOX activity were evaluated at three conditions. The enzyme was most active with H...

The changes in the components of the ascorbateglutathione system during the storage of potato {Solanum tuberosum L. cv. Spunta) tubers for 40 weeks at both 3 C and 9 C were studied in relation to lipid peroxidation. The level of malondialdehyde was found to be higher at 3 C than at 9 C throughout storage. Thus, lipid peroxidation, which is the main cause of membrane deterioration, was accelerat...

In this study, the effects of some environmental storage conditions – light, temperature and humidity on the stability of the steroidal drug, hydrocortisone sodium succinate injection were investigated. The drug samples were stored at varying conditions of light, temperature (0C, 28C and 60C) and humidity, after which each sample was assayed at weekly intervals for their content of the drug usi...

Mouse bone marrow cells were stored for 0.5, 16 and 24 hours under one of the following four conditions; saline G at room temper ature, saline G at ice temperature, CMRL 1066 at room temperature and CMRL 1066 at ice temperature. Their viability was then examined by counting CFU in the spleen of irradiated recipient mice. 1) The CFU decreased rapidly with storage time under all four conditions. ...

The effect of storage temperature on the viability of Trichophyton mentagrophytes in infected guinea pig skin scales was quantitatively evaluated for 182 days. Infected skin scales were stored, while protected from light, in glass containers with desiccant at four temperatures and sampled after saline treatment at various time intervals. No decrease in viability was observed for storage at 4 de...

Background: Given the concerns about the use of chemical preservatives in food, the consumers and producers have been interested in natural alternatives, such as plant essential oils and extracts. Since there are limited studies about the effect of saffron (Crocus sativus L.) on the behavior of foodborne pathogens in food models, this study aimed to determine the inhibitory effect of aqueous ex...

The aim of this study was to investigate the effects of starters and storage temperature (4 ºC, 25 ºC) onmicrobiological and physicochemical properties, volatile compounds and sensory evaluation of kefir.Kefirs produced by KFA and Chr. Hansen starters were stored at 4 ºC and 25 ºC for 40 days. pH andacidity at 4 ºC did not change (p ≥ 0.05), while at 25 ºC pH and total solid decreased as well a...

The grape juice industry has shifted almost entirely from the old method of storing juice in 5-gallon carboys to cool storage in tanks at 22 to 28 F (-5.5 to -2.2 C). Excess tartrates are precipitated during storage. When juice was stored in carboys, the carboys wNere filled at processing temperature, and either spray-cooled or allowed to cool slowly at the cellar storage temperature. For the m...

Several pBR DNA plasmid storage conditions were evaluated in this study, including the storage form (liquid or dried on 3M paper), the buffer used to dissolve the plasmid, and temperature. Storage in the liquid form resulted in increased colony formation compared to DNA dried on paper, which is a more convenient and often preferred method for shipping plasmids. The TE buffer was superior to aut...
