In this current scenario with changing food habits, escalating population and unrestricted use of natural resources, there are lacking of resources to provide nutritious food to all. Natural plant resources are fast depleting and need to explore new alternatives. Besides the staple rice and wheat; lots of underutilized crops are being consumed that are having great potential to replace the staple crops. Millets are one of the major underutilized crops with a Nutri-cereal potential. Millets are highly nutritive, non-acid-forming, gluten-free and having dietary properties. Despite the fact that millets are highly nutritious, their consumption is still limited to the conventional and poor population due to lack of awareness towards its nutritional values. There is lack of processing technologies, lack of food subsidies and inconvenience in food preparations which makes millets more obsolete. Millets are Nutri-cereals and rich in carbohydrates, dietary fibres, energy, essential fatty acids, proteins, vitamin-B and minerals such as calcium, iron, magnesium, potassium and zinc, which helps to prevent from post-translational diseases like, diabetes, cancer, cardiovascular and celiac diseases, etc. Millets help in controlling blood pressure, blood sugar level and thyroid but inspite of these functional properties, millets consumption is still declining. Millets utilization in-combination with other staple food crops to develop food alternatives has become an emerging area for food industries. Besides, to strengthen our fight against malnutrition in children and adolescents, consumption of millets can help to foster immunity and health. Here, author's have reviewed the potential of millets for their Nutri-cereal qualities. [ABSTRACT FROM AUTHOR]

The growing demand for sustainable animal production is compelling researchers to explore the potential approaches to reduce emissions of greenhouse gases from livestock that are mainly produced by enteric fermentation. Some potential solutions, for instance, the use of chemical inhibitors to reduce methanogenesis, are not feasible in routine use due to their toxicity to ruminants, inhibition of efficient rumen function or other transitory effects. Strategies, such as use of plant secondary metabolites and dietary manipulations have emerged to reduce the methane emission, but these still require extensive research before these can be recommended and deployed in the livestock industry sector. Furthermore, immunization vaccines for methanogens and phages are also under investigation for mitigation of enteric methanogenesis. The increasing knowledge of methanogenic diversity in rumen, DNA sequencing technologies and bioinformatics have paved the way for chemogenomic strategies by targeting methane producers. Chemogenomics will help in finding target enzymes and proteins, which will further assist in the screening of natural as well chemical inhibitors. The construction of a methanogenic gene catalogue through these approaches is an attainable objective. This will lead to understand the microbiome function, its relation with the host and feeds, and therefore, will form the basis of practically viable and eco-friendly methane mitigation approaches, while improving the ruminant productivity.

Methanogens, the members of domain Archaea are potent contributors in global warming. Being confined to the strict anaerobic environment, their direct cultivation as pure culture is quite difficult. Therefore, a range of culture-independent methods have been developed to investigate their numbers, substrate uptake patterns, and identification in complex microbial communities. Unlike other approaches, fluorescence in situ hybridization (FISH) is not only used for faster quantification and accurate identification but also to reveal the physiological properties and spatiotemporal dynamics of methanogens in their natural environment. Aside from the methodological aspects and application of FISH, this review also focuses on culture-dependent and -independent techniques employed in enumerating methanogens along with associated problems. In addition, the combination of FISH with micro-autoradiography that could also be an important tool in investigating the activities of methanogens is also discussed. [ABSTRACT FROM AUTHOR]
