The Influence Of Processing On The Chemical And Electrophoretic Patterns Of Water-Soluble And Salt-Soluble Proteins In Blue Crabs., Orthnell George Dowdie

LSU Historical Dissertations and Theses

Raw and processed Blue crab meat were investigated to determine the influence of processing temperature on the distribution of water soluble and salt soluble proteins, using sodium dodecyl sulfate polyacrylamide gel electrophoresis in conjunction with photodensitometry. Analysis of the raw crabmeat protein showed 30 water soluble and 45 salt soluble protein subunits. Salt soluble proteins were composed of subunits whose molecular weights were much more variable than the water soluble protein subunits. Salt soluble proteins were found to have molecular weights of 12,000-160,000 daltons, whereas the water soluble subunits were of molecular weights 12,000-130,000 daltons. There were significant differences (P < 0.001) in the changes between the number of bands present in the raw crabmeat and the number retained after processing at 100(DEGREES)C; however, the level of significance was only changed to (P < 0.05) when raw crabmeat was compared to crabmeat processed at 121(DEGREES)C in steam. Salt soluble proteins were more heat labile than the water soluble proteins. At 70(DEGREES)C, the total level of salt soluble protein was reduced 57% compared to the levels in raw meat, whereas, the water soluble proteins were reduced only 13%. Processing temperatures were found to significantly influence (P < 0.05) the pH of the processed meat as well as the water in which the crabs were processed. Correlation coefficients of r = 0.7604 and r = -0.6401 were found between changes in pH and basic and acidic groups. These coefficients were significant at (P < 0.05). Analysis of Blue crab hemolymph for copper revealed the copper content to be approximately eight times greater than quantities found in the meat. Nine proteins were found in the hemolymph with 3 of the proteins being complexed with copper (hemocyanins). The hemocyanins had molecular weights of 58,000, 71,000 and 95,000 daltons. The subunit with a molecular weight of 58,000 daltons contained approximately 65% of the total copper in the hemolymph.

Ultrastructural - Biochemical Changes And Sensory Correlations In Shrimp During Cold Storage., Teck Muk Wong

LSU Historical Dissertations and Theses

Ultrastructural-biochemical changes and sensory correlations of penaeid shrimp during iced and frozen storage were analyzed. The aroma, color and acceptability of "wild" shrimp, P. setiferus from the Gulf of Mexico, were judged by six trained panelist to be superior to that of the pond-raised shrimp, P. stylirostris. However, P. stylirostris on the Master Mix Shrimp Diet has a slightly superior flavor than those fed with the Marine Ration 20 diet. Free amino acids, proline, glycine, taurine, and glutamic acid declined during the first 10 days of ice storage, and increased after 20 days. Leucine, and lysine increased linearly during ice …

Genetic Structure Of Pinus Strobus L Based On Foliar Isozymes From 27 Provenances, Jang-Bal Ryu

Doctoral Dissertations

Genetic structure of eastern white pine (Pinus strobus L.) was studied with foliar isozymes from 27 provenances by starch gel electrophoresis. Twenty-one loci, five fixed, coding for 12 enzyme systems, including three invariants, were used for this study. Indirect evidence for genetic control of these loci was discussed.

Substantial genetic differentiation within and among provenances was evidenced according to several indices. Based on 12 loci, mean values of average heterozygosity, proportion of polymorphic loci and number of alleles per locus per provenance were .236, .69 and 2.01, respectively. By partitioning of total genetic diversity into its components, interprovenancial allele differentiation …

Characterization And Bioavailability Of Alfalfa Leaf Protein Concentrate., Sirous Kashefi

LSU Historical Dissertations and Theses

Pressed alfalfa juice at pH 8.5 was heated (60(DEGREES)C) and centrifuged to produce a brown solution. This solution was further heated (80(DEGREES)C) at pH 4.0, centrifuged, and freeze-dried to produce a light tan powder. Tetrahymena pyriformis W. was used to test quality of cytoplasmic and chloroplastic fractions of alfalfa leaf protein concentrate (ALPC). Chloroplastic ALPC supported poor cell growth, probably because of high concentrations of chlorophyll, fat, and chlorogenic acid to which Tetrahymena is reported to be sensitive. Data indicated that isoleucine, phenylalanine, threonine and sulfur-containing amino acids in cytoplasmic ALPC were higher than those in soybean. Data indicated cytoplasmic …

Effects Of Insecticide-Herbicide Interactions On Soybean Plants Grown On Eight Louisiana Soils., Henry Clifford Hill Jr

LSU Historical Dissertations and Theses

In 1979, a study was initiated to determine if selected rates of aldicarb(2-methyl-2(methylthio)propionaldehyde O-(methylcarbamoyl oxime), trifluralin (a,a,a-Trifluoro-2, 6-dinitro-N, N-dipropyl-p-toluidine) and metribuzin (4-amino-6-(1, 1-dimethylethyl)-3-(methylthio)-1, 2, 4-triazin-5(4H)-one), applied alone and in combination, resulted in phytotoxic reactions in soybeans, Glycine max (L.) Merr. var. Davis. The three greenhouse studies and one field-greenhouse study were conducted on eight selected Louisiana soils to determine to what extent the soil characteristics affected the biological activity of these combinations. The trifluralin-containing treatments used in this study, generally, produced stunted, thick-stemmed plants with smaller and fewer nodules than the non-treated check plants. However, N(,2) C(,2) H(,2) activity was …

Energy In Agriculture: Energy Resource Series For Youth And Adult Energy Programs: 3. Oil And Gas, George M. Turner

Agricultural Engineering Energy Series

The oil and gas in the earth today were formed many millions of years ago, long before humans appeared on the scene. Therefore, man can only theorize about the origin of these fossil fuels.

The most widely accepted theory is that the oil and gas found in the earth today had their beginnings in decomposed animals and plants. The decomposition was caused by bacteria and chemicals called enzymes which digested the plant and animal bodies.

Energy In Agriculture: Energy Resource Series For Youth And Adult Energy Programs: 9. Wood, George M. Turner

Agricultural Engineering Energy Series

Wood is a bio-fuel. This means that it comes from living things. Lawn grass, field crops and garden plants and flowers are all in the bio-family of living things. In fact, there is no difference between the wood of today and fossil fuels of aeons ago, such as coal and oil except time. Millions of years ago all fossil fuels were lush green plants, thriving on nutrients and moisture in the earth and the photosynthesis process. These have long since died but have been preserved beneath the surface of the earth. Actually, the wood of today and the fossil fuels …

G81-556 Using The California Mastitis Test (Cmt) To Detect Subclinical Mastitis, Duane N. Rice

University of Nebraska-Lincoln Extension: Historical Materials

Apparently healthy cows can harbor subclinical mastitis, which creates tremendous loss in milk production. This NebGuide offers a method for detecting this disease.

The dairyman is generally aware of clinical mastitis because it can be seen as changes in the milk, swollen udder and other signs exhibited by the cow. Compared with subclinical mastitis, clinical mastitis is much less costly, is of short duration, tends to be an individual cow problem, and is detected without special tests.

Unfortunately, the apparently healthy cow can harbor subclinical mastitis, which creates tremendous loss in milk production. A cow with subclinical mastitis does not …

Bulletin 3929 - Irrigation In Western Australia, K S. Cole

Bulletins - 3000 - 3999

Irrigation is essential in many parts of the world to produce essential food and profitable cash crops. Generally, those areas of land with less than 360 mm of rain spread over a distinct wet season of several months cannot grow crops for food or cash on rainfall alone. Then irrigation becomes necessary unless some peculiarity such as an oasis exists.

The Agricultural Potential Of The Middle Kuskokwim Valley, John S. Lewis

Bulletin

Alaskans are concerned with the production of food . This is evident from the concern which has been expressed over the subsistence issue within the current Alaska lands legislation. The debate ponders who shall harvest the state's natural game resource and how the resource shall be harvested. Although this question is not settled , one point is coming to the fore: the game resource alone is not sufficient to satisfy the food needs of Alaska's growing rural population. In recent months, interest has been expressed in the agricultural potential of the lands in areas of Alaska which are removed from …
