“…This is unexpected because fungi are crucial to the breakdown of the majority of organic and inorganic wastes in the environment, and it is consistent with earlier research by Nimkar et al (2010). In recent times, conversion of agricultural wastes to useful products has been by microorganisms through their enzymatic property (Manikandan et al, 2022). Values are mean of duplicate readings and standard error of mean and values on the same column with same alphabets is not significantly different at P < 0.05.…”

The oxidation of glucose produces gluconic acid, a significant organic acid. The aim of this study was to produce gluconic acid from sweet potato peels by submerged fermentation. Isolation and identification of fungi were done using standard microbiological methods. Proximate analysis of substrate and screening of fungal isolates for gluconic acid production was done using standard procedures. Gluconic acid yields were determined using High Performance Liquid Chromatography. A standard gluconic acid producer, Aspergillus niger ATCC 10577, was used as control. A sum of six different fungal species were isolated and identified. They included Aspergillus niger, Aspergillus flavus, Penicillum sp., Cladosporium sp., Rhizopus stolonifer and Aspergillus terreus. Proximate composition of the sweet potato peels showed percentage carbohydrate of 20.81 ± 0.07, percentage moisture of 64.02 ± 0.27. Screening for gluconic acid production showed that Aspergillus niger had the highest zone of clearance and identified as Aspergillus niger UFMGCB 14248. Our data further showed that gluconic acid concentrations (mg/ml) was highest at substrate concentration 50 g/L, carbon source starch, incubation day 7 and pH 6 for both Aspergillus niger UFMGCB 14248 and Aspergillus niger ATCC 10577. The findings showed that the fungal isolates used in this study were good gluconic acid producers

“…Different waste sources (industrial, agro-industrial, agro-food, and others.) contain biopolymers in the good amount [19,34,41,[43][44][45][46][47]. Using renewable resources for biopolymer production provides benefits such as reduced reliance on fossil fuels, waste management, resource recovery, and the creation of added value.…”

Uncontrolled waste generation and management difficulties are causing chaos in the ecosystem. Although it is vital to ease environmental pressures, right now there is no such practical strategy available for the treatment or utilisation of waste material. Because the Earth's resources are limited, a long‐term, sustainable, and sensible solution is necessary. Currently waste material has drawn a lot of attention as a renewable resource. Utilisation of residual biomass leftovers appears as a green and sustainable approach to lessen the waste burden on Earth while meeting the demand for bio‐based goods. Several biopolymers are available from renewable waste sources that have the potential to be used in a variety of industries for a wide range of applications. Natural and synthetic biopolymers have significant advantages over petroleum‐based polymers in terms of cost‐effectiveness, environmental friendliness, and user‐friendliness. Using waste as a raw material through industrial symbiosis should be taken into account as one of the strategies to achieve more economic and environmental value through inter‐firm collaboration on the path to a near‐zero waste society. This review extensively explores the different biopolymers which can be extracted from several waste material sources and that further have potential applications in food packaging industries to enhance the shelf life of perishables. This review‐based study also provides key insights into the different strategies and techniques that have been developed recently to extract biopolymers from different waste byproducts and their feasibility in practical applications for the food packaging business.

“…In this sense, sustainability is often explained applying three dimensions (society, economy, and environment) [42]. These mentioned realities involve all three dimensions of sustainability and integrate the energy dimension and fuelling into a potential circular economy [43]. On this basis, the wine sector has recently experienced a market growth that is different from other agricultural sectors, increasing its cultivated areas.…”

Grapevine Resistant Cultivars: A Story Review and the Importance on the Related Wine Consumption Inclination

Pest and disease management in the grapevine sector has become difficult due to several instances (e.g., pathogen resistance, agrochemicals withdrawals). Therefore, viticulture switched to more environmentally friendly practices. On these bases, the most promising tool is the use of a resistant variety of grapes. Luckily, genetic and genomic selection have made great steps in accelerating plant breeding. In recent years, several resistant varieties of grape were created and the wine obtained began to grow. This allowed vine growers and wine makers to drastically reduce the chemical inputs in vineyards. However, this specific wine market faces trouble regarding the consumer attitude towards buying the related crafted wines. In order to make these innovations acceptable, we undertook a literature review of the history and creation methods of the hybrid grapevines. We investigated young wine drinkers across north-east Italy using specific questionaries to better analyse consumer perception of wine from resistant vines and the related environmentally friendly issues to understand if consumers are prone towards this product. Our results clearly indicate that consumer attitude towards this type of beverage pays great attention to the reduction in agrochemicals.
