One potent lactic acid bacterial strain C14 with strong antifungal activity was isolated from homemade curd. Based on morphological as well as biochemical characters and 16S rDNA sequence homology the strain was identified as Lactobacillus fermentum. It displayed a wide antimicrobial spectrum against both Gram-positive and Gram-negative pathogenic bacteria, and also against number of food spoil...
Bioluminescent bacteria require myristic acid (C14:0) to produce the myristaldehyde substrate of the light-emitting luciferase reaction. Since both endogenous and exogenous C14:0 can be used for this purpose, the metabolism of exogenous fatty acids by luminescent bacteria has been investigated. Both Vibrio harveyi and Vibrio fischeri incorporated label from [1-14C]myristic acid (C14:0) into pho...
In experiments preliminary to the possible use of carbon-14-labeled Stilbamidine in the treatment of humans with multiple myeloma (2, 9, 26) it was found in normal mice that no abnormal concentra tion of Stilbamidine persisted in any tissue and that over 90 per cent of the injected radioactivity was excreted within a month (20). A tracer dose of C14-labeled Stilbamidine was then given to a hu m...
Slices from adipose tissue and liver were incubated with uniformly labeled C14-isoleucine and the respiratory carbon dioxide, fatty acids, and nonsaponifiable lipids were isolated and analyzed for radioactivity. Organic acids were qualitatively identified by chromatography and autoradiography. Adipose tissue oxidized isoleucine to carbon dioxide a t a rate greater than that of liver. Conversion...
In this study, oil was extracted from the liver and visceral fat of Patin (Pangasianodon hypophthalmus) and refined. The yield of oil after refining was 49.98%. The major yield loss (34.20%) happened during the degumming procedure. Fatty acids found in the crude and refined oil were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6. The ...
Verticillium wilt (VW) caused by Verticillium dahlia Kleb is one of the most destructive diseases of cotton. Numerous efforts have been made to improve the resistance of upland cotton against VW, with little progress achieved due to the paucity of upland cotton breeding germplasms with high level of resistance to VW. Gossypium barbadense was regarded as more resistant compared to upland cotton;...
Two type of adulterants i.e. soybean oil (SO) and buffalo depot fat (BDF) along with pure cow and buffalo milk fats, collected and prepared after every two months of interval for a complete one year, were analyzed for their fatty acid composition using gas liquid chromatography. Both the adulterants were added individually at 5, 10 and 15 percent levels (v/v) as well as in their combinations at...
The molecular determinants of stimulation of -1 programmed ribosomal frameshifting (-1 PRF) by RNA pseudoknots are poorly understood. Sugarcane yellow leaf virus (ScYLV) encodes a 28-nt mRNA pseudoknot that promotes -1 PRF between the P1 (protease) and P2 (polymerase) genes in plant luteoviruses. The solution structure of the ScYLV pseudoknot reveals a well ordered loop 2 (L2) that exhibits con...
In the past, investigators have used thyroxine labeled either with JIP" in the 3',5'-position or with C14 in the carboxyl position to study the metabolism of thyroxine in vivo. Although these studies have yielded much valuable information, our knowledge about the metabolic fate of the ring structure in thyroxine is incomplete because both the 3'5'-IJ13 and the carboxyl-C14 are rapidly removed f...
