This paper aims to address the issue of food security and its role in the inclusion of edible and medicinal mushrooms in the diets of nutritionally vulnerable populations in Colombia, allowing an overview of the nutritional situation and its main structural causes, the importance of food security programs, the advantages and disadvantages of the use of mushrooms and strategies and challenges in promoting the cultivation and consumption of macromycetes.

An extensive literature review was conducted to develop this viewpoint paper.

According to the results of this study, for edible fungi to become a viable alternative in the Colombian food culture, it is necessary to develop strategies and educational programs for food security, to conduct applied research to assess the incorporation of mushrooms into the food culture of the communities and to consider the acceptability of this food. This requires promoting the properties of mushrooms and considering their nutritional and/or medicinal contributions, self-consumption, commercialization to buy other food and the utilization of by-products or agricultural residues for cultivation, all while paying heed to the implications of food safety and regulations. The contributions of different professionals in social and technical areas in transferring knowledge to the community, and especially to “replicator leaders”, is also of great relevance to the acceptability of these ideas within communities.

Edible fungi are a possible response to malnutrition problems in adult and infant populations in Colombia.

No previous study has investigated the potential of mushrooms as a strategy to decrease food insecurity in Colombia.

This paper aims to isolate fungal strains producing natural colours, explore their application as colourant in paints and develop cost-effective durable natural paints.

Fungal strains producing natural colours of different shades were isolated. Colourant production was carried out by fermentation method. Natural lime, milk, oil-in-water emulsion paints using natural microbial colours and eco-friendly ingredients were prepared. Bio-paint applications were carried out and evaluated.

Our results indicate that microbes in general and fungi in specific represent dependable source of variety of natural colours, and cost-effective durable natural paints can be prepared with commonly available natural ingredients using scientific information based on history of paints.

Natural colours are gaining importance because of their use in health, nutrition, pharmaceutical, textile and environmental applications. Nature is quite rich in several types of colourants. Chemical synthesis of synthetic dyes is complex and not environmental friendly. Microbial dyes manufactured can evade inherent environmental problems of synthetic dyes and offer significant opportunity as a colourant in paints. However, only generally regarded as safe microbial strains are to be considered for colour production.

Choosing natural alternatives to protect the health and environment is the need of hour. Fungal colourants are relatively more stable and robust and offer significant opportunity as a colourant in paints. Cost-effective durable natural paints can be prepared using selected stable fungal colourants with commonly available natural ingredients. High diversity of rich and complex natural colourants can be obtained from microorganisms. With the available techniques of fermentation, natural colours can be produced in large quantities of on an economically viable scale and explored for their applications.

Bio-paints are eco-friendly natural paints, low volatile organic compounds (VOC) paints or organic paints alternate to conventional paints. Most of these natural paints are durable, breathable, prevent moisture problems, contribute to a positive room climate, use safer technology and are less energy-intensive than conventional latex paints to produce. These paints improve indoor air quality and reduce urban smog and offer beneficial characteristics such as low odour, excellent durability and a washable finish.

Many of the old art works that still survive today are a tangible proof and evidence of beauty and durability of natural paints. Organic materials used in these paints include natural pigments of mineral, plant and animal origin and other raw biodegradable ingredients. Successful commercialisation of many microbial pigments for food and textile applications is reported in literature. Therefore, present research work aims at developing natural paints using microbial pigments and recipes that have been successfully used by people for years.
