Endophytic fungi produce various mixtures of carbon-based compounds, which are known as volatile organic compounds (VOCs). Research regarding the use of VOCs as pesticide substitutes has garnered much attention. This review summarizes the recent knowledge about VOCs regarding their origin and chemical properties and emphasizes their antimicrobial potential against a wide variety of agricultural pathogens. Several studies have highlighted the importance of VOCs as antimicrobial agents. Nevertheless, the application of VOCs in biofumigation methods still requires the advanced evaluation of their phytotoxicity.

Food waste (FW) is seen as an obstacle to achieving food and nutrition security and food systems sustainability. It is known in literature that households are significant contributors to the total amount of FW. This paper reports on results of an online survey that was conducted from February to April 2015 with a random sample of 281 Tunisian adults. The aim of the survey is to assess the knowledge and relative importance of FW; attitudes towards FW; impacts of behaviors regarding food and food management; quantity and value of FW; as well as barriers and willingness to behavioral change. The sample was not gender-balanced (71.2% female and 28.8% male). The majority of the respondents was young (70.8% aged between 18 and 34 years) and has high education level (95.4% having university and PhD degrees). Food waste is prevalent in Tunisia as about the half of respondents declare that they throw food. The most wasted food products are fruits, vegetables, and cereals and bakery products. Only 42.7% of respondents declared that the economic value of food waste generated each month is more than 6US$. Most of Tunisian respondents have a good understanding of food labels that is probably due to the high education level of the sample. About 37% of respondents throw weekly at least 250 g of still consumable food. To reduce FW in Tunisia it is important to set a strategy at all food chain levels. There is also an urgent need to raise people's and organizations awareness towards this problem. This article provides a basis for the development of other more context specific investigations and interventions for the prevention of household FW in Tunisia.
