Biodegradation of polyethylene: a brief review

Abstract: Plastic waste management and recycling became a serious global issue as it affects living beings from all the ecosystems. Researchers investigated biodegradation of polyethylene (PE) by measuring changes in various physico-chemical and structural characteristics using techniques like as fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), etc. However, these evidences are not enough to prove the exact biodegradation of PE. In this review, we summarized microbial biodegradation of polyethylene and discussed recent developments for the candidate microbial enzymes and their possible roles in PE degradation. In addition, we conversed the advanced technologies correctly used for measuring PE degradation using isotope-labeled PE to figure out its metabolism into the end products like as 13CO2.

Responses of the phenolic compounds of Zea mays under heavy metal stress

Abstract: Heavy metal toxicity is one of the major abiotic stresses caused by physiological and biochemical changes. Plants have evolved various phytochemical defense mechanisms to cope with this abiotic stress conditions. Phenolic compounds are one of the stress responses and have multiple roles in respect to adaptation of plants to the environment. In the present study, we aimed to evaluate the differential accumulation of various phenolics with HPLC in the leaves of corn exposed to increasing heavy metal doses in the plant growth medium. The application of Cd, Cu, and Pb increased the total phenolics in all treatments compared to control groups. Chlorogenic acid and rutin were the main phenolic compounds in respect to quantifying. However, the contents of caffeic acid, ferulic acid, and vanillic acid were comparatively lower than chlorogenic acid and rutin in all samples. The content of chlorogenic acid significantly increased and rutin slightly increased in the treatment of the heavy metals. The levels of caffeic acid and ferulic acid significantly decreased in all exposures of heavy metals compared to control groups. The content of vanillic acid changed according to heavy metal types and doses in the leaves of corn, and the low doses of Pb and Cd increased the level of vanillic acid. We show that there is a positive correlation with the total phenolic content and chlorogenic acid when the corn is exposed to Pb. Moreover, there are negative correlations between total phenolic compound and caffeic acid, ferulic acid in the application of Cu and Cd.

Recent advances in control technologies for non-point source pollution with nitrogen and phosphorous from agricultural runoff: current practices and future prospects

Abstract: Eutrophication of natural water is a universal problem. Nitrogen (N) and phosphorus (P) from agricultural runoff are the main sources of nutrient input, provided that emissions from industrial point sources (IPS) are under control. Therefore, it is of great environmental importance to reduce pollution associated with agricultural runoff as a means of regulating eutrophication levels in natural water. Numerous methods proposed for treating agricultural runoff can be classified into three categories: source control, process control, and end treatment. In this review, major technologies for N and P control from agricultural runoff are summarized along with discussion of newly proposed technologies such as biochar biomimetics and microbial catalyst. Because agricultural runoff (from farmlands to receiving waters) is a complicated pollution process, it is difficult to regulate the nutrients discharged via such process. This review will thus offer a comprehensive understanding on the overall process of agricultural runoff and eutrophication to help establish control strategies against highly complicated agricultural non-point sources.

Crosstalk between reactive oxygen species and pro-inflammatory markers in developing various chronic diseases: a review

Abstract: The inflammation process in the human body plays a central role in the pathogenesis of many chronic diseases In addition, reactive oxygen species (ROS) exert potentially a decisive role in human body, particularly in physiological and pathological process The chronic inflammation state could generate several types of diseases such as cancer, atherosclerosis, diabetes mellitus and arthritis, especially if it is concomitant with high levels of pro-inflammatory markers and ROS The respiratory burst of inflammatory cells during inflammation increases the production and accumulation of ROS However, ROS regulate various types of kinases and transcription factors such nuclear factor-kappa B which is related to the activation of pro-inflammatory genes The exact crosstalk between pro-inflammatory markers and ROS in terms of pathogenesis and development of serious diseases is still ambitious Many studies have been attempting to determine the mechanistic mutual relationship between ROS and pro-inflammatory markers Therefore hereby, we review the hypothetical relationship between ROS and pro-inflammatory markers in which they have been proposed to initiate cancer, atherosclerosis, diabetes mellitus and arthritis

Screening for Antioxidant Activity of Plant Medicinal Extracts

Abstract: The antioxidant activities of 80% methanol extracts obtained from 118 medicinal plants were tested through the evaluation of DPPH and superoxide anion radicals scavenging activity. Methanol extracts of Sophora japonica (76.9%) and Camptotheca acuminata Dence (50.9%) were found to have more than 50% DPPH radical scavenging activity while those of Perilla frutescens (37.2%), Amomum costatum (34.9%), Prunus ansu (33.2%), Mentha arvensis (32.3%), Serratula koreana (32.2%), Eriobotrya japonica (30.5%), and Artemisia asiatica (30.5%) showed more than 30% scavenging activity. Even though all of the commercial antioxidants didn't show superoxide anion radical activity, Mentha arvensis (87.7%), Eriobotrya japonica (84.9%), Amomum costatum (82.9%), Camptotheca acuminata Dence (82.1%) showed more than 80% scavenging activity. Mentha arvensis, Eriobotrya japonica, Amomum costatum, Camptotheca acuminata Dence showed strong antioxidative activity in the both DPPH and superoxide anion radical scavenging activities.
