Mostrar más [+] Menos [-]Antimicrobial Activity of Various Plant Extracts on Pseudomonas Species Associated with Spoilage of Chilled Fish Texto completo
2016
Osan Bahurmiz | Rosma Ahmad | Noryati Ismail | Frederick Adzitey | Shaida-Fariza Sulaiman
The antimicrobial activity of various plant extracts on Pseudomonas bacteria isolated from spoiled chilled tilapia (Oreochromis sp.) was evaluated in this study. In the first stage of this study, red tilapia was subjected to chilled storage (4°C) for 3 weeks, and spoilage bacteria were isolated and identified from the spoiled fish. Pseudomonas was the dominant bacteria isolated from the spoiled fish and further identification revealed that P. putida, P. fluorescens and Pseudomonas spp. were the main species of this group. In the second stage, methanolic extracts of 15 selected plant species were screened for their antimicrobial activity, by agar disc diffusion method, against the Pseudomonas isolates. Results indicated that most of the extracts had different degrees of activity against the bacterial isolates. The strongest activity was exhibited by bottlebrush flower (Callistemon viminalis) extract. This was followed by extracts from guava bark (Psidium guajava) and henna leaf (Lawsonia inermis). Moderate antimicrobial activities were observed in extracts of clove (Syzygium aromaticum), leaf and peel of tamarind (Tamarindus indica), cinnamon bark (Cinnamomum zeylanicum), wild betel leaf (Piper sarmentosum) and fresh thyme (Thymus spp.). Weak or no antimicrobial activity was observed from the remaining extracts. The potential antimicrobial activity shown by some plant extracts in this study could significantly contribute to the fish preservation.

Cemil Kürekci | Mustafa Yipel | Sevda Pehlivanlar Önen
The purpose of this study was to determine the antibacterial activity of plant derived compounds and essential oils of Corymbia citriodora against selected Gram negative and Gram positive foodborne pathogens in broth dilution assay. The combination of compounds (cineole, terpinen-4-ol and α-terpineol; CTαT) were further tested at three different concentrations (0.2, 0.4 and 0.8%) for the killing effect against E. coli O157:H7 and L. monocytogenes in milk including whole fat and skim fat. CTαT showed antimicrobial activity against all bacteria tested at minimum inhibition concentrations (MICs) from 0.125% to 1% in broth dilution assay. Linalool was also found to be antimicrobial at MICs between 0.25% and 2%, but not for Enterococcus casseliflavus. Further study carried out in milk showed that CTαT at concentrations of 0.4% and 0.8% significantly reduced the population of E. coli O157:H7 under detection limit in skim milk, whereas it was only effective at 0.8% in whole fat milk. CTαT, on the other hand, shown to be less active towards L. monocytogenes as only significant effect was observed at 0.8% in skim milk. Taken together results of the present study indicate that plant derived compounds could be valuable alternatives to inactivate foodborne pathogens in milk.

Oseni Kadiri | Babatunde Olawoye | Olumide S Fawale | Olusoji Adeola Adalumo
Pawpaw (Carica papaya Linn) seeds, peels and leaves are well known for their medicinal and potent pharmacological values. The plant belongs to the family Caricaceae and its fruit is commonly known for its food and nutritional values. Though the roots, bark, peel, pulp and the seeds had been shown to have medicinal properties, little is known about their nutritional properties. During the last few years, there had been series of research to explore further pharmacological and medicinal properties as well as it nutritional qualities of these plants parts, thus giving rise to it nutraceutical abilities. Scientific attempts have also been made over the decades to authenticate its nutraceutical properties. While nutritional constituents such as oil, proteins, and minerals haven been characterised from its seeds, little is known about other parts of the plant. Though the nutraceutical properties of papaya as drug or quasi-food product are not well understood or value, still it is an important gift of nature that is readily available in our eco-world and worth exploring. This review focuses on previous studies by various researchers on the medicinal, nutraceutical properties as well as the antioxidant potential of these plant parts and suggestions for further studies as regarding the optimisation of the potential of this plant.

Edmond Ahipo Due | Koffi Djary Michel | Yolande Dogore Digbeu
In Sub-Saharan Africa, especially, in Côte d’Ivoire, the wild edible mushroom Termitomyces heimii Natarajan is the most prized and widely consumed for different reasons such as taste, flavour, attractiveness, uses as substitutes for meat or fish and medicinal values. The present study was aimed at evaluating the proximate composition and functional properties of T. heimii flour for further food products formulation. Fresh mushroom T. heimii were obtained from the market of Aboisso (5° 28′ 06″ N and3° 12′ 25″ W) in Côte d’Ivoire. The fresh mushrooms were dried and ground to obtain the crude flour. Chemical composition and functional properties were investigated using standard methods. The chemical composition revealed that it contains crude protein about 23.75%, crude fat 3.58%, moisture 11.59 %, ash 7.40%, total carbohydrate 54.70% and energy value of 345.90 kcal/ 100 g. These results suggest that T. heimii can be used in human diet to prevent undernourishment due to protein. Furthermore, the low fat content suggest that it would be an ideal food for obese persons and useful in preventing hypertension and hypercholesterolemia. The functional properties showed that it has high bulk density and water absorption capacity with values of 0.737 g/mL and 315.15 ± 45.74% respectively. This flour exhibited also good foaming properties. All these characteristics make it suitable as good thickeners in food products, useful in foods such as bakery products which require hydration and attractive for products like cakes or whipping topping where foaming is important. The mushroom T. heimii could be utilized for making some low-fat foodstuffs and snacks with considerable protein content. The mushroom flour shows good functional characteristics for use in many food industries.

Mostrar más [+] Menos [-]A Natural Intuition Underlying Vernalization Case in Plants: Epigenetic Texto completo
2016
Behcet İnal | Serdar Altıntaş
Plants have developed a number of monitoring systems to sense changes occurring in the environment and to coordinate their growth and development accordingly. Some plant groups have cold exposure requirement for a certain period to induce flowering. That process known as vernalization is case in point for mentioned systems. In many plants group, vernalization results in repression of floral repressor genes inhibiting floral transition. In this review, last epigenetic developments about vernalization mediated floral transition in Arabidopsis regarded as model organism for plants and other flowering plants will be discussed. Furthermore, similarity and differences in regulatory cycles in Arabidopsis and other flowering plants, changes in histone modifications at floral repressor loci and other epigenetic systems effective in vernalization will be discussed. To sum up, profound investigation of epigenetic mechanism behind the vernalization process plays an important role to decrease flowering-dependent yield losses.
