The chemical constituents of crude oil were evaluated in this study. Crude oil is used for many purposes. It is commonly used for production of fuel and in traditional medicine for various purposes. Some people also use crude oil as antidote for poisons. Analysis of the chemical constituents of crude oil was carried out with the use of GC (model No. 7890B) and MS detector (model 5977A). Several chemical constituents with various functions were detected in the crude oil. Some of the chemical constituents detected have been reported to be used for the production of some fuels, pesticides, volatile compounds, fragrance, food additives and antimicrobial agents. This study therefore showed that various important chemicals/compounds useful in traditional medicine and for industrial uses are present in crude oil, thereby making it a good raw material for industrial and medicinal purposes. However, some constituents of crude oil are known to be able to cause toxicity, making crude oil a toxic substance.

This paper describes the botanical features ofFicus caricaL. (Moraceae), its wide variety of chemical constituents, its use in traditional medicine as remedies for many health problems, and its biological activities. The plant has been used traditionally to treat various ailments such as gastric problems, inflammation, and cancer. Phytochemical studies on the leaves and fruits of the plant have shown that they are rich in phenolics, organic acids, and volatile compounds. However, there is little information on the phytochemicals present in the stem and root. Reports on the biological activities of the plant are mainly on its crude extracts which have been proven to possess many biological activities. Some of the most interesting therapeutic effects include anticancer, hepatoprotective, hypoglycemic, hypolipidemic, and antimicrobial activities. Thus, studies related to identification of the bioactive compounds and correlating them to their biological activities are very useful for further research to explore the potential ofF. caricaas a source of therapeutic agents.

Collection And Management

It has been discovered that absence of education and security in any society gives room to lawlessness and crises. This paper brings to bare the effect of waste collection and management on poverty reduction. Polythene is a by- product of crude oil. It is otherwise known as polyethylene. The use of polythene in the society is enormous and when poorly managed, constitutes at least 40% of the wastes that accumulate in the municipal. This paper views waste collection and management especially polythene as a tool for reducing poverty in the society. The emergence of recycling industries provided the platform for re-use of polythene materials thereby, making it an industrial raw material for some industries.

Ginger (Zingiber officinale) has been widely used in traditional medicine, and as raw material for cosmetics, beverages, and health functional foods. However, some adverse effects of ginger have been reported. In addition, the hot and pungent taste of ginger leads to reduced consumption. To overcome these problems, methods for the production of fermented, steamed (or steamed-dried), aged, roasted and beopje ginger have been developed. This review provides an overview and summary of new ginger processing procedures, including methods to reduce the pungent flavor of ginger, extend shelf-life, increase the health-functional compound content, and improve safety. These attempts might improve the consumption of ginger as well as prospective applications of processed ginger for food, cosmetics, and the pharmaceutical industry, also as discussed in various patents.

Effective Result

Mycotoxin is widely known as one cause of foodborne disease, produced by toxigenic fungi. Any country should be aware about this high risk potency by knowing the mycotoxin, affected commodities, fungal sources, and toxicity effect to human or animal. Controlling mycotoxin could be done by physic, chemical, and biological methods. The microbial characteristic used for biological agent should be evaluated including the inability to produce toxic substance, tendency to multiply, colonize, survive, safety, and applicability to the environment. Studies related to mycotoxin biocontrol by using antagonistic microorganism can be focused on (1) the effect to the mycotoxin, (2) the growth of microorganism, or (3) the application to food both raw material and processed products. Consideration to combine more than one species of microorganism instead of a single species also has been taken to achieve more effective result.  For example, S. cerevisiae has been used together with LAB to control certain mycotoxin. Further studies are needed to develop the possibility of other biological agents and the effect of their application, which in the next have the potency as manufacturing products.

Abstract Sulfur dioxide is considered as an extremely harmful and toxic substance among the air pollutants emitted from the lignite- and other high-sulfur-coal based power plants, old tires processing units, smelters, and many other process industries. Various types of absorbents and desulfurization technologies have been developed and adopted by the industries to reduce the emission rate of SO2 gas. The present paper focuses on the ongoing advances in the development of varieties of regenerative and non-regenerative absorbents viz., Ca-based, Mg-based, Fe-based, Na-based, N2-based, and others along with various FGD technology, viz., wet, dry or semi-dry processes. Additionally, different types of contactors viz., packed column, jet column, spray tower, and slurry bubble columns along with their significant operational and design features have also been discussed. In the existing or newly installed limestone-based FGD plants, an increasing trend of the utilization of newly developed technologies such as limestone forced oxidation (LSFO) and magnesium-enhanced lime (MEL) are being used at an increasing rate. However, the development of low-cost sorbents, particularly suitable solid wastes, for the abatement of SO2 emission needs to be explored sincerely. Many such wastes cause air pollution by way of entrainment of fine particulate matter (PM), groundwater contamination by its leaching, or brings damage to crops due to its spreading onto the cultivation land. One such pollutant is marble waste and in this work, this has been suggested as a suitable substitute to limestone and cost-effective sorbent for the desulfurization of flue gases. The product of this process being sellable in the market or may be used as a raw material in several industries, it can also prove to be an important route of recycling and reuse of one of the air and water-polluting solid wastes.

The nicotine, reducing sugar and ion contents from the threshing of tobacco can re-used from the industry. The crude oil and fatty oil compositions of tobacco seeds can be considered as an alternative source of raw material for biodiesel. In this study, the nicotine, reducing sugar content, crude oil, fatty acid composition and ion content were determined in 29 genotypes and 1 cultivar of tobacco. The genetic diversity was determined among the tobacco cultivar and genotypes base on examined properties. The nicotine content varied between 0.10-0.87%, reducing sugar ranged from 9.70-21.30%, crude oil varied between 24.33-47.00% and fatty acid compositions was found in the range of 77.94-100%. Linoleic (13.92-75.04%) and butyric (0.33-64.98%) acids were the major components. Overall, the BSR-5 (52.56 mg/g) and ESR-5 (44.58 mg/g) genotypes exhibited the highest potassium contents and ESR-7 (6.54 mg/g) and ESR-8 (1.28 mg/g) genotypes had the lowest chlorine contents. As a result of this study, the highest nicotine content, reducing sugar and crude oil of tobacco were found in ESR-4, ESR-11 and BSR-5 genotypes, respectively. The dendrogram analysis divided the tobacco into two main groups and most of the same origin genotypes fell into the same group. The results indicated that the different tobacco leaves and seeds can be evaluated as an alternative source in the industry as cigarettes, biodiesel and different industrial applications such as cosmetic, oil paints and varnishes based on their chemical properties.

BACKGROUND: A possible reduction in stocks of medicinal plant raw materials of Thymus serpyllum L. and Thymus vulgaris L. leads to the need to expand the raw material base of the official medicinal plants with using of endemic species of the flora of Kazakhstan, in particular, Thymus rasitatus Klokov, and Thymus eremita Klokov. AIM: The aim of the study was to study the possibility of using 70% ethanol extracts of T. rasitatus and T. eremita as antimicrobial agents. MATERIALS AND METHODS: The aerial parts of T. rasitatus and T. eremita were extracted with 70% ethanol using ultrasound assisted extraction. The qualitative and quantitative analyses of the 70% ethanol extracts were determined using the liquid chromatography-detection-ESI-mass spectrometry-(MS)/MS technique. The study of the antimicrobial activity of these extracts was performed for eight strains of Gram-positive bacteria, six strains of Gram-negative bacteria, and four cultures of fungi. RESULTS: Chromatographic analysis of hydroalcoholic extracts of both investigated Thymus species showed very similar phenolic compounds composition. In both cases, the major components are luteolin-7-O-glucoside and rosmarinic acid. About 70% ethanol extracts of T. rasitatus and T. eremita have a broad spectrum of antimicrobial activity, exhibit the bactericidal or bacteriostatic activity against all tested bacteria and fungi at concentration range of 0.0195–20 mg/ml, but differ in their potency against tested strains of microorganisms. CONCLUSION: About 70% ethanol extracts of T. rasitatus and T. eremita, endemic plants in the flora of Kazakhstan, can be considered as potential drugs with a wide spectrum of antimicrobial activity. The results of chromatographic analysis could be used for drug standardization.

The sub-optimum conditions of Nigeria conventional refineries remains a drastic setback since all other industries are intertwined with its outputs. It is noted that amidst all other glaring contributing factors as listed in the study, insufficient large capital funds on the part of private investors and vandalization of pipelines seems to be conspicuous. The stolen crude oil got from the pipelines serve as the beginning point for illegal refining. Asides the issue of quality control of products, their sub-standard operation also affects Nigerians environmentally and economically. The more the Government invest time and resources to stop their operation; the more they spring up like mushrooms. This paper reflects the authors view on achieving a win-win scenario. The upgrading of existing illegal refineries at strategic locations within the country to standard modular refineries seems to be a more feasible and friendly approach. The issue of channeling of intermediate products can be solved through the introduction of clusters, where final products of one become raw material for the other. Intermediate products can also be channeled to Government owned conventional refineries for further processing. From analysis, it is deduced that overall design capacities from clusters have optimum effect on the intermediate environment in terms of meeting demand. Extensive operational training on crude oil refining will help buttress the point while Transfer of Knowledge from official vendors to Nigerian Engineers on how to fabricate modular refining units locally will also help to reduce overall cost.
