2016
Serap Coşansu | Özlem Kıymetli
Sous vide is a cooking method in which food is heat processed after vacuum packaging in heat stable pouches. Meat, chicken, fish and vegetables can be cooked by this method; even meals containing these ingredients can be preserved by heat processing after precooking and vacuum packaging steps. Meanwhile sous vide cooking is a preservation method that the product is cooled rapidly after heat processing and can be stored for long periods. By this method, food can be cooked in vacuum packed without losing its flavour, taste and nutritional value. In this review, the effects of sous vide cooking on the major nutrients of vegetables such as antioxidant compounds and vitamins will be mentioned.

Lupin seeds of genetically improved cultivar (Golo) were subjected to different processing methods and investigated according to anti-nutritional factors content and protein quality. Results showed that tannin content of raw seeds was significantly increased in sprouted and debittered seeds before and after boiling but in fermented seeds it declined significantly. Phytate content was significantly decreased in all processed seeds with a significant reduction observed in germinated seeds. The reduction in Phytate as a result of processing was accompanied by a significant improvement in protein digestibility. The protein content of lupin seeds decreased in sprouted seeds and increased in fermented and debittered ones. Boiling of the seeds even the sprouted ones significantly increased the protein content compared to raw lupin seeds. In raw lupin seeds, globulins comprised the major fraction followed by glutelin. Debittered seeds characterized by high glutelin, fermented are characterized by high globulin while germinated characterized by both fractions. Most of the amino acids level was increased after processing of the seeds.

In this study was carried out to determine the effects of humic acid in heavy metal stress of lettuce changes in some of the morphological and physiological characteristics. In studies conducted in controlled greenhouse conditions, lettuce plants subjected to four different 4 different humic acid levels humic acid doses (0, 2, 4, 8 L/da) and 4 different heavy metal irrigation levels (Control: 0 ppm; I. mixture: 0.2 ppm Cu + 0.01 ppm Cd + 5 ppm Pb + 2 ppm Zn; II. mixture: : 0.4 ppm Cu + 0.02 ppm Cd + 10 ppm Pb + 4 ppm Zn; III. mixture: 0.8 ppm Cu + 0.04 ppm Cd + 20 ppm Pb + 8 ppm Zn). Four weeks after at heavy metal and humic acid treatment young plants were harvested and the shoot fresh and dry weight, root fresh and dry weight, shoot and root length, and leaf areas, MDA, superoxyde dismutase (SOD) and glutathione reductase (GR) were determined. The most highly toxic effects were determinate III. mixture level (0.8 ppm Cu + 0.04 ppm Cd + 20 ppm Pb + 8 ppm Zn). MDA and antioxidative enzyme activities increased in plants irrigated with water containing a mixture of heavy metal. Humic acid applications had a positive effect on reducing of the limiting effect of heavy metal stress on growth and development.

WRKY transcription factors are a class of DNA-binding proteins that bind with a specific sequence C/TTGACT/C known as W-Box found in promoters of genes which are regulated by these WRKYs. From previous studies, 43 different stress responsive WRKY transcription factors in Arabidopsis thaliana, identified and then categorized in three groups viz., abiotic, biotic and both of these stresses. A comprehensive genome wide analysis including chromosomal localization, gene structure analysis, multiple sequence alignment, phylogenetic analysis and promoter analysis of these WRKY genes was carried out in this study to determine the functional homology in Arabidopsis. This analysis led to the classification of these WRKY family members into 3 major groups and subgroups and showed evolutionary relationship among these groups on the base of their functional WRKY domain, chromosomal localization and intron/exon structure. The proposed groups of these stress responsive WRKY genes and annotation based on their position on chromosomes can also be explored to determine their functional homology in other plant species in relation to different stresses. The result of the present study provides indispensable genomic information for the stress responsive WRKY transcription factors in Arabidopsis and will pave the way to explain the precise role of various AtWRKYs in plant growth and development under stressed conditions.

Five strains of Lactococcus, including L. garviae K2, L. piscium SU4, L. lactis subsp. cremoris E22, L. plantarum L7 and L. lactis subsp. hordinae E91 were screened for production of antimicrobial agents. The strains were also analysed for antimicrobial activities against spoilage and pathogenic organisms, including Staphylococcus aureus, Salmonella Typhimurium, Escherichia coli, Yersinia enterocolitica, Pseudomonas aeruginosa, Klebsiella pneumoniae, Listeria monocytogenes, Bacillus cereus and Pseudomonas fluorescens. Result revealed that L. piscium SU4, L. plantarum L7 and L. lactis subsp. cremoris E22 had lactic acid production (g/107 colony forming units, CFU) of 7.23, 7.20 and 7.19. The value of 6.83 recorded as lactic acid produced by L. garviae K2 was significantly different from those obtained for others. The highest acetic acid production (3.55 g/107 CFU) was recorded for L. garviae K2 while L. piscium SU4 had the lowest (2.99 g/107 CFU). L. lactis subsp. hordinae E91 had diacetyl production of 71.99 (µg/107 CFU), which was higher than those recorded for other Lactococcus strains. Test for antimicrobial activities showed that Escherichia coli NCTC 86, Yersinia enterocolitica NCTC 10460, Pseudomonas aeruginosa NCIMB 10848, Bacillus cereus NCTC 21113 and Pseudomonas flourescens recorded higher susceptibilities to the antimicrobial action of the Lactococcus strains than others; zones of inhibition of 5 mm and above were recorded for the indicator organisms compared to lower values (

The study was carried out to estimate the temperature, light intensity, salinity, Dissolved O2 (DO), pH values and the biotic parameter chlorophyll- a in the water column related with the depth. Because, the physico-chemical parameters affect greatly both primary and secondary producers in marine life. For this purpose the physico-chemical properties were determined day and night for 40 meter depth during the eight days. The means were compared by using the analysis of variance method and Duncan’s Multiple Comparison Test. Also physico-chemical parameters were estimated by using the analysis of regression and correlation. The effect of temperature and salinity were found significant according to the result of the analysis of variance during the day. Also the similar results were found for the night. While the effect of the depth on the chloropyll-a a was significant in the night, the effect of the depth on the DO was not significant in the day and night. The correlations among the depth and the parameters were defined. It was found the negative correlation between the depth and the temperature and light intensity. Determination coefficient of the model for salinity was also found different for day time. The correlation values among the depth and the temperature, salinity and pH were found different for the night.

The aim of this study was to determine the growth parameters of European Flounder fry (Platichthys flesus luscus L. 1758) caught from the nature in different feeding methods in aquaculture conditions. The study was conducted between April and July 2011, and the fish were collected at the connection point of Sarıkum Lagoon with the Black Sea in Sinop Province using seines and large scoops. A total of 750 European Flounder with the average weight of 0.93±0.01 (0.71-1.21) g were stocked in 5 groups with 3 repetitions. The groups were organized according to the feeding protocols [G1:90 days Chironomid larvae (CL), G2:60 days CL+30 days CL+ granular feed (GY), G3:30 days CL+60 days CL+ GY, G4:90 days CL+GY, G5:90 days GY]. At the end of the study, the weights of the fish were determined as 10.83±0.51, 9.89±0.22, 6.33±0.21, 5.13±0.11, 3.81±0.09, respectively. It was found that feeding preferences of the fish had significant effects on weight gain, specific growth rate, feed conversion ratio and survival rate. European Flounder fry, as in their natural habitat, mostly preferred natural feed moving in the deep in the production site. It was determined that using live feed as the starter feed for the adaptation of European Flounder fry had a significant effect on growth parameters and survival rates.
