Several groups of molds such as Aspergillus sp., Penicilium expansum, Botrytis cinerea, and Venturia sp. can cause a serious postharvest disease exhibited as watery regions where areas of blue-green tufts of spores develop.

The most promising species for industrial feed production was the black soldier fly (Hermetia illucens), the mealworm (Tenebrio molitor), and the two-spotted cricket (Gryllus bimaculatus). Regarding research areas of the patents reviewed here, studies on the composition and optimal mixing ratio of feeds and on insect rearing, harvesting, and post-harvest technologies were mainly performed for the industrial mass production of safe and functional animal feeds containing insects. Continuous scientific innovations and improved processing technologies will aid further advancements in this field.

Cassava flour has the potential to substitute 70-80% of wheat flour as the main ingredient for wet noodle production. Unfortunately, cassava flour has no gluten and lower protein content than wheat flour, which is important for the characteristic of a wet noodle. Therefore, transglutaminase (MTGase) is often applied in non-gluten products to improve its texture. This enzyme catalyzes the reaction between lysine and glutamine to form isopeptide cross-links. Moreover, the addition of MTGase to cassava-based wet noodle improves its texture and color. In addition, this effect gives better palatability for wet noodle. This enzyme can increase the shelf life of wet noodles and safe for our health.

Sustainable agriculture enable us to produce healthy food without harming natural resources. However, this agriculture depends on successful management of resources for agricultural in order to fulfil the requirements of increasing human population by improving the quality of crop plants and preserving natural resources. Plant growth promoting rhizobacteria (PGPR) are soil inhabitant bacteria that have some useful effects on soil properties and plant health. Plant growth promoting rhizobacteria can play a significant role to achieve sustainable agriculture. The use of PGPR is environment friendly way to enhance crop yields and to facilitate plant growth. PGPR gained more attraction because of their low cost and simple mode of action. They can be used singly or in combination but the combined use of PGPR always resulted incredible results on sustainable agriculture. PGPR are now used regularly to stimulate plant growth and productivity. However, the use of useful bacteria for sustainable agriculture and increase in crop yield needs the collection of capable root-colonizing bacteria which have confirmed plant growth potentials. Use of PGPR reduce the applications of chemical fertilizers which have unfriendly effects on environment. PGPR have the ability to produce broad variety of secondary metabolites, allelo-chemicals, which play pivotal role in plant sustainability and reactions to abiotic stresses. Besides PGPR, endophytic fungi can also play a key role in nutrient availability, protection of plants against various diseases and stresses and thus lead to sustainable agriculture. Endophytic fungi exist widely inside the healthy tissues of living plants, and are important components of plant micro-ecosystems. This Special Issue is focused on introducing the latest interesting findings on plant-microbe interactions and their role in plant growth and development, as well as in sustainable agriculture and sustainability of soils.","PeriodicalId":21061,"journal":{"name":"Recent patents on food, nutrition & agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38401005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
