Musa Yalman | Seda Özdikmenli Tepeli | Nükhet Nilüfer Demirel Zorba
In our country, there are many cheese types that are produced traditionally. Cheeses which produced from cows, sheep and goat milk that matured with spontaneous growth of molds present in livestock skins, pots and similar environments are among them. They are produced traditionally in Mediterrian, Central and Eastern Anatolia regions. Molds that grow spontaneously in cheeses could create public health risk because of their secondary metabolites. Penicillium spp. are the most isolated mold from these cheeses and Penicillium roqueforti is determined as the dominant species. Furthermore, Aspergillus, Alternaria, Mucor, Geotrichum, Cladosporium species have been isolated. It is very important to control the ripening conditions and starter strain selection since some strains were reported as mycotoxin producers. In this review, it has been tried to give general information about traditional production of mold-ripened cheese in Turkey and the mold flora found in traditional cheeses. In addition, public health risk of these cheeses is reported.

Mohamed Thabet
Historically relegated to the status of “poor man’s bread” barley is one of widely cultivated crops in arid regions of south Tunisia for its grain and biomass used as an animal feed and other various purposes. Barley is incorporated into many types of home recipes. Harsh climate and frequent droughts are the great challenge for cereals production so farmers must supply irrigation in order to improve yields. Traditional irrigation techniques are widely used despite their low efficiency. Conversion to drip is encouraged by public services as a measure to save water resources, boost yields and as an adaptation measure to climate change that will cause more pressure on available water resources .The present paper presents results for drip irrigated barley in arid climate of South Tunisia. The study was undertaken at research farm of Institute of Arid Regions in Medenine and tried to replicate current farmer’s practices with the aim to facilitate their conversion to drip irrigation. For full drip irrigated barley (100% irrigation water requirements), following crop variables were recorded according to standard agronomic procedures as described in Daur et al. (2011): Plant height (m); Ears number by square meter at harvest; Number of grains per ear; 1000 grain weight (g); Biological yield (kg.m-2); Grain yield at harvest (g.m-2). Grain yield was 360.75g m-2 which corresponds to 3.61 ton ha-1and Biological yield was 1.014 kg m-2 for a total water amount of 225 mm. These values far exceed those obtained in rainfed agriculture.

The commercial production of cultivated-mushroom, which has a forty years of past in Turkey, was started after 1980s. Until the recent decade, most of the total amount of production in Turkey was performed by family members while the cultivation of the product has gained an upward trend since the beginning of 2000s, though the amount and development rate were not enough. During that time, a number of large (>2000 m2) and medium (500-2000 m2) scale mushroom production facilities were established and Turkey has gained an important place in mushroom production in the world. In this study, we aimed to reveal the common production methods of ten medium and large scale mushroom companies whose daily production capacities are above 1 ton in six regions. In this respect, all companies have been visited and communicated directly with company representatives and a survey comprising 65 questions about company, production facility, compost and casing soil, production systems, diseases and pests and packaging was made. The findings have suggested us that such companies have mostly a history of 15 years of time and have a land size of 10-50 thousand m2, while their mushroom production areas vary between in size and that they make use of technology in production and automation in their plants and they have quality management systems (ITU, ISO 9001, ISO 22000 and Global Gap ) and they employ generally qualified and experienced technicians or agriculture engineers and also that 40% of them receive consultancy and also that they use their own productions or standard ready mycelium planted compost and that they use domestic peat as casing material and that they package the mushrooms with their brands and sell to markets mostly and lastly that they conduct pre-sale quality sorting and grading. It was also seen that there is lack of food engineers employed and most of the companies do not receive consultancy, and that the waste compost is not evaluated correctly and that the covering material is not in the required standards and that there are even companies not doing any water analysis and that coal for heating and chemicals for disinfection are used and that diseases and pests are inevitable and last that they lack in processing different products.

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.

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.

A field survey was conducted to study the factor that determines farmers’ decisions to adapt to climate change in Deurali and Agyouli V.D.Cs of Nawalparasi District. Altogether 180 household, 90 from each V.D.C were selected randomly for the study. A logit regression model was employed in the study. However, in order to measure the magnitude of the impact of the explanatory variables on the decision of the farmer to adapt to climate change marginal effects were computed. The study uses a binary dependent variable taking the value 1 if the farmer adapted to climate change and 0 otherwise. A farmer is considered to have adapted to climate change if he/she has employed at least one of the adaptation strategies such as early and late planting, use of drought resistant crops, zero tillage operation, crop diversification, use of mulching and composting of weeds to control water loss and conserving moisture in the field. This current research considers the following as potential factors determining farmers’ decisions to adapt to climate change; economically active members, education of the household head, farm size, annual cash earnings, access to credit, training and extension. Findings reveal that these factors influence farmers’ decisions to adapt to climate change in Nawalparasi District and marginal effects computed showed that per unit increase in these variables increased the probability of practicing different adaptation strategies by 4.3%, 31.4%, 3%, 1.5%, 17%, 66% respectively. The log likelihood was computed to be -43.45. Psuedo. R2 was calculated to be 39%.
