“…Maize contains bioactive components that provide multifunctional physiological effects for the body, including strengthening the immune system, regulating the rhythm of physical conditions, slowing down aging, and helping prevent disease. Several bioactive ingredients such as phenolic acids as the major chemical compound, flavonoids, carotenoids, vitamin E, and phytosterols [7][8][9]. In different maize endosperm, the content of calories, water/ash, total carbohydrate, sugar, total fat, protein, calcium, iron, magnesium, niacin, potassium, riboflavin, thiamine, sodium, Vitamin A, Vitamin C, and Zinc will be different [10,11].…”

One of the main obstacles to maize farming is the extensive loss of yields caused by the investment of the Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae) during the storage period. This pest attacks maize kernels in the active larval stage; they burrow, attack, and hide in seeds. Some research reports that this pest attack can cause damage between 18-20%; in conditions of high water content, the damage rate can reach 30-40%. In addition to direct damage, this pest attack can reduce product and nutritional quality, seed weight, and the percentage of germination, which will reduce market value. Besides being able to cause severe damage to maize kernels, this pest also attacks several other agricultural products in stockpiles, such as sorghum, rice, wheat, and processed food products such as pasta and biscuits. This paper reviews several significant research results on the insect pest Sitophilus zeamais Motsch. In the future, it is hoped that it will provide helpful information for researchers and academics everywhere.

“…These studies can demonstrate the wide distribution of BPA-degrading microorganisms. Since there are diverse phenolic compounds in plants, bacteria with the ability to degrade them can be found in soils containing decaying plants ( 20 ). In this regard, the main novelty of the current study was isolation and identification a BPA-degrading bacterium from soil samples containing decaying plants with no history of contamination with petroleum derivatives.…”

Background and Objectives: Bisphenol A (BPA) is a toxic compound with broad applications in the plastics industry. BPA has harmful effects on various organisms and its efficient removal is necessary. The microbial degradation of BPA is a safe and economical approach. In this research, soil samples containing decaying plants were screened to isolate a BPA-degrad- able bacterial strain. Materials and Methods: Soil samples were collected from different locations in Damghan, Semnan province, Iran. To enrich BPA-degrading bacteria, the samples were cultured in a stepwise manner in a mineral medium containing increasing BPA concentrations (5 to 40 mg/L). The ability of isolated bacteria in degrading BPA was assayed by Folin-Ciocalteu and high-performance liquid chromatography methods. The biodegradation efficiency of the most efficient isolate was assayed under distinct conditions and it was identified through the sequencing of the 16S rRNA gene. Results: Among the isolated bacteria, Pseudomonas aeruginosa DU2 (GenBank accession number: OP919484) showed the most BPA biodegradation ability. The highest BPA degradation (52.98%) was observed in the mineral medium containing 5 mg/L BPA and the inoculum size of 6 × 107 CFU/mL at pH 9 and in the presence of 0.05% (w/v) NaCl during 10 days. Conclusion: These results offer soil containing decaying plants as a promising source for finding BPA-degrading bacteria. P. aeruginosa DU2 has basal BPA removal ability, which could be improved by optimization of medium components and growth conditions.

Phenolic compounds are the major contaminates in wastewater, which can have a considerable negative influence on the environment and health of human. Adsorption is an efficient process that is widely applied in order to eliminate phenol in wastewater. In recent, Adsorption process has acquired a lot of attentiveness owing to its relative moderate operating conditions. However, adsorption process needs considerable ameliorations in terms of adsorbent modification, process type, productivity, and conversion rate. This work studies the development of a fast and effective adsorption process in a fixed bed adsorption column (FBAC) in order to reach safe and continuous elimination of phenolic compounds. Several adsorption parameters (reaction temperature, adsorbent bed height, feed flow rate and kind of adsorbent) were studied to achieve the highest removal of phenolic compounds. The adsorption process was conducted in the presence of two type of adsorbents (activated carbon (AC), and KOH/AC), 73% and 94% of phenol elimination were attained, respectively, at 10 cm bed height, 1 ml/s feed flow rate, and 75 °C reaction temperature. The adsorbents activity was investigated after six consecutive adsorption cycles at the best process conditions, and the adsorbents show high stability in terms of phenolic compounds adsorption. After that, the spent adsorbents were regenerated by utilizing various solvents (methanol, ethanol and iso-octane), and the results show that iso- octane achieved highest regeneration efficiency. The adsorption process was implemented in the adsorption column that the performance is possibly to be adjusted at an industrial scale since it can be scaled up predictably.
