“…Extract ready in that technique is divided from the leaf filtrate and then mixed with a solution of Fe2+. The iron ions in the occurrence of polyphenols remained reduced to nZVI [7]. This green filters procedure for producing iron nanomaterials is considered as the most ecofriendly method and is still now commonly used.…”

“…Contingent upon leaf category and application of phytochemicals reactions, nanomaterial remain complete within a limited time, although microorganism-based methods require a longer time. The main disadvantage of microorganism nanomaterial production is the required limitation of sterilized situations, which needs qualified supervisor, and increases the scalingup charge [8].Green filter ZVI has been positively used as a Fenton catalyst for oxidizing monochlorobenzene [11].The reducing agent are used dye such as malachitegreen [12] or bromothymol blue [7]. Former research"s show the report of green nZVI it can be used to damage medicines (e.g.…”

“…These issues emphasize the importance of recovery, recycling, and upgrading of processing waste in all industries. Currently, the food processing industry is a huge business with a turnover of billions of dollars, and generates enormous quantities of wastes, residues, and by-products [1]. It is very important that these available resources should be recognized appropriately as raw material for deriving either new products of commercial importance or products of added values [2,3].…”

The large amounts of solid biological wastes produced in industrial activities increases production costs. As a consequence, it is common to develop strategies to reuse these wastes by transforming them for usage in other processes/industries. This paper is the first paper examining the use of garlic by‐products as bioresource. This study delineates firstly the physicochemical and biological characterization of garlic by‐products such as straw and peels, secondly provides the various applications of garlic by‐products in different domains and unveils their potential for industrial applications such as feed alimentation, soil amendment and bioenergy. They presented potential exploitation as bioadsorbents for wastewater treatment. Finally, these by‐products could be exploited for further industrial purposes such as extraction of bioactive components and extraction of functional ingredients and production of phenolic compounds and biofuel such as biogas and bio‐oil. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1765–1777, 2017

“…In recent years, a sufficient number of studies have been accumulated to substantiate the prospects for the use of nano-materials in microelectronics [1], energy physics [2], chemical [3], food [4], pharmaceutical [5], medical industry [6][7][8]. Nanoparticles (NPs) of metals are also of great practical importance in agriculture (in particular, in plant growing and for increasing soil fertility), where they can be used as nano-herbicides [9], nano-pesticides [10], as plant growth stimulants [11] and nano-fertilizers [12].…”

A b s t r a c tWith the accumulation of experimental data it is evident that nanomaterials, which are widely used in human activity, look promising for agronomy. However, available publications on a comprehensive assessment of biological risks arising from nanoherbicides, nanofertilizers, etc., in particular on how the metal nanoparticles affect geobionts, are very limited. In the model experiments with California red worms Eisenia foetida as test organisms we studied the influence of aluminum oxide nanoparticles on soil biocoenosis and their biodegradation. We found an increase in mortality of worms up to 20 % at the maximum dosage of aluminum oxide nanoparticles introduced into the soil. Assay of antioxidant defense enzyme activity in the E. foetida revealed an increased superoxide dismutase and catalase level as influenced by the studied nanoparticles. The positive effect of their vermicomposting was shown. At increasing content of aluminum oxide nanoparticles (the nanoparticle dosage of 50, 100, 300, and 3000 mg/kg in the groups 1, 2, 3, and 4, respectively), the 61.7-67.6 % reduction in soil microorganism counts was found without vermicomposting vs. 55.6-61.3 % under vermicomposting. The number of microorganisms in the soil decreased in the groups 1, 2, 3 and 4 by 42.8, 52.4, 61.9 and 76.2 % for fungi, by 64.3, 77.9, 78.6 and 85.7 % for nitrogen-fixing bacteria, and by 22.7, 38.6, 84.1 and 86.4 % for bacteria cultured on starch-and-ammonia agar. The number of cellulolytic bacteria increased by 6.9 % in the group 1 and decreased by 16.7, 12.5 and 25.0 % in the groups 2, 3 and 4, respectively. A similar trend was observed under the influence of aluminum oxide nanoparticles on the E. foetida intestinal microflora. As the soil content of aluminum oxide nanoparticles increased from 50 to 3000 g/kg, the total number of microorganisms in the E. foetida intestine decreased by 9.7 to 43.2 %. In this, fungi decreased in the groups 1, 2, 3 and 4 by 18.0, 20.0, 39.0 and 40.0 % as compared to control. The number of nitrogen-fixing bacteria was insignificant in the control samples and decreased in the E. foetida intestine in the groups 1, 2, 3 and 4 by 16.0, 60.0, 78.8 and 80.0 %. The cellulolytic bacteria counts increased in the intestine of E. foetida (by 16.0 %) at minimum nanoparticle dosages, whereas in the groups 2, 3 and 4 this index was lower by 8.0, 32.0, 25.0 and 40.0 %. The number of bacteria cultured on starch-and-ammonia agar decreased in the E. foetida intestine in groups 1, 2, 3 and 4 by 13.3, 46.7, 60.0 and 73.3 %. Therefore, our data indicate dose-dependent effects of aluminum oxide nanoparticles and gradual development of their toxicity toward soil and intestinal microflora at increasing levels in the soil. The negative impact of the aluminum oxide nanoparticles on soil biocenosis was shown that was manifested in its depletion, leading to soil degradation and decreased fertility. We confirmed the necessity for complex assessment of nanoparticle biotoxicity in a variety of habitats. The antioxidant syst...
