This study examined the effects of long-term frozen storage (-20 °C for 5 months) of free amino acids (FAAs) and nucleotide-related compounds (NRCs) in muscle and hepatopancreas of the coconut crab Birgus latro. Although long-term frozen storage had little effect on FAA composition in muscle, the amounts of several FAAs increased in the hepatopancreas that may be the result of protein decom...
This study determined the effects of cold storage on the survival, development and reproduction of the mymarid wasp, Gonatocerus ashmeadi Girault (Hymenoptera: Mymaridae). Following storage of the immature parasitoids within host eggs of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae) under a daily fluctuating temperature for up to 50 d, the quality of...
An extra period under cold air after ultra-low oxygen storage has been shown to increase the concentration of some volatile compounds emitted by stored 'Fuji' apples. The purpose of this work was to assess the role, if any, of lipoxygenase and hydroperoxide lyase activities in the regeneration of fruit capacity for volatile production after ultra-low oxygen storage. Fruits were stored at 1 °C a...
Three species of flies were examined for chilling tolerance from the end of the pupariation to the onset of adult eclosion for the purpose of determining applicability for cold storage. For the housefly, Musca domestica (Diptera, Muscidae), survival to eclosion was affected by developmental stage/age, length of storage, and storage temperature. Houseflies that were closest to having experienced...
BACKGROUND In modern biotechnology, there is a need for pausing cell lines by cold storage to adapt large-scale cell cultures to the variable demand for their products. We compared various cell culture media/solutions for cold storage of Vero-B4 kidney cells, a cell line widely used in biotechnology. RESULTS Cold storage in RPMI 1640 medium, a recommended cell culture medium for Vero-B4 cells...
Apple is one of the most important fruits in temperate zones with a long post-harvest life during cold storage. A factorial experiment, in a randomized completely block design was used to investigate the preharvest application of Iron (0, 500 and 1000 mg Fe-EDDHA per tree) and nitrogen (0, 48 and 96 g ammonium nitrate per tree( on some postharvest qualitative characteristics in "Red spur" and "...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
