Background: Despite the wide application of Xanthan gum, its commercial production remains a global challenge. In recent years, considerable research has been carried out using agro-industrial wastes, which are renewable and abundantly available to produce value-added products. The present study was set out for molecular identification of Xanthomonas campestris from leaves of four different plants with indications of dark rot spots and evaluation of their xanthan gum production capacity. Methods: Twenty-five (25) samples of leaves from four different plants with indications of dark rot spots were collected from the study area and isolated for Xanthomonas campestris following standard microbiological methods. Cultural, morphological and biochemical tests were conducted to confirm the organism. Results: The results revealed that of the total 100 samples taken, 6 leaves (24%) were infected with Xanthomonas species in mint, 3(12%) were infected in mango, 1(4%) were infected in rice and 2(8%) were infected in pepper. Further molecular identification of the isolates was carried out to reveal Xanthomonas campestris pv. vesicatoria strain 85-10 and Xanthomonas perforans strain 91-118. These were further used for the production of xanthan gum using sugar cane molasses substrates extracted from sugar cane, which was used as fermentation medium for the production. Isolates from plants varying ability in Xanthan gum production, with the mint plant having the highest Xanthan gum production (0.10 ± 0.02 to 0.9 ± 0.00 g/l). Conclusion: The present study confirmed the high xanthan gum production capacity of Xanthomonas campestris from dark rot spots containing mint leaves and should be considered during local and industrial production of the xanthan gum

Abstract Phenol is considered as an important platform molecule for synthesizing value-added chemical intermediates and products. To date, various strategies for phenol transformation have been developed, and among them, selective hydrogenation of phenol toward cyclohexanone (K), cyclohexanol (A) or the mixture KA oil has been attracted great interest because they are both the key raw materials for the synthesis of nylon 6 and 66, as well as many other chemical products, including polyamides. However, until now it is still challengeable to realize the industrilized application of phenol hydrogenation toward KA oils. To better understand the selective hydrogenation of phenol and fabricate the enabled nanocatalysts, it is necessary to summarize the recent progress on selective hydrogenation of phenol with different catalysts. In this review, we first summarize the selective hydrogenation of phenol toward cyclohexanone or cyclohexanol by different nanocatalysts, and simultaneously discuss the relationship among the active components, type of supports and their performances. Then, the possible reaction mechanism of phenol hydrogenation with the typical metal nanocatalysts is summarized. Subsequently, the possible ways for scale-up hydrogenation of phenol are discussed. Finally, the potential challenges and future developments of metal nanocatalysts for the selective hydrogenation of phenol are proposed.

ABSTRACTThe low quality of raw rubber materials produced by farmers is a classic problem. Farmers cultivate only hereditary sap crops into the clot, printed in the freezer and the results tub-shaped “slab” in various sizes. Prices received is relatively low, due to the weak bargaining position that would otherwise be beneficial to make a clean “bokar”. A factory units with creper mini is a business opportunity for farmers – traders who have sufficient capital investment. Creper mini machine is used to process the material rubber into blankets. Processing alternatives be blanketed capable to improving the quality and the price at the farm level. However, the lack of capital will hinder business continuity, while the production capacity should remain unfulfilled. This article is a reviews of case studies in factory units with creper mini on Banyuasin district, South Sumatera. The study analyzes were conducted to understand the financial aspects of the operations with financial eligibility criteria NPV, B/C ratio, IRR and PP. NPV results Rp. 1.225.200.360,-, B/C Ratio 1,02, IRR 32%, and PBP 2,1 years or 25 months. Business continuity rubber processing factory units with mini creper is feasible. Efforts to provide value-added is a large capital investment, as well as potential raw materials to meet the production capacity. ABSTRAK Rendahnya mutu bahan olah karet yang dihasilkan oleh petani menjadi problema klasik yang terjadi hingga saat ini. Biasanya petani karet hanya mengolah lateks hasil kebun yang dicetak dalam bak pembeku dan hasilnya berbentuk slab dengan berbagai ukuran. Hal ini mengakibatkan harga yang diterima petani relatif rendah, karena lemahnya posisi tawar yang seharusnya dapat ditingkatkan apabila membuat bokar bersih. Keberadaan unit pengolahan karet creper mini dapat menjadi bagian dari upaya peningkatan mutu bokar, sekaligus peluang usaha bagi petani-pedagang yang memiliki modal untuk berinvestasi. Mesin creper mini berfungsi untuk mengolah bokar atau slab tipis menjadi blanket. Alternatif pengolahan bokar menjadi blanket di unit pabrik pengolahan karet creper mini diharapkan akan meningkatkan mutu dan harga di tingkat petani. Tulisan ini adalah ulasan dari studi kasus pada unit pabrik pengolahan karet creper mini yang berada di Kabupaten Banyuasin, Sumatera Selatan. Kajian dilakukan untuk mengetahui kelayakan finansial dari kegiatan usaha pengolahan karet dengan creper mini. Indikator kelayakan finansial yang digunakan adalah NPV, B/C ratio, Internal Rate of Return, dan PBP. Hasil perhitungan NPV sebesar Rp. 1.225.200.360,- , B/C ratio 1,02, IRR 32% dan PBP 2,1 tahun atau 25 bulan. Dengan demikian, usaha Unit Pengolahan Karet dengan Creper Mini dinilai layak untuk dilakukan. Upaya pengembangan usaha untuk memberikan nilai tambah yang lebih besar adalah dengan modal investasi yang besar, serta menjamin ketersediaan bahan baku secara berkelanjutan guna memenuhi kapasitas produksi creper mini.

Abstract The paper analyzes the relationship between value added tax revenue and intermediate consumption in the case of Romania in the period January 2007 – September 2018 (quarterly data), using an unrestricted Vector Autoregression Model based on the rate of dynamic taxation’s level (in terms of value added tax revenue) and the rate of dynamic intermediate consumption. In literature, is questioned only the relationship between tax revenue and gross domestic product. Our study emphasizes the link between tax revenue and parts of the own tax base. The relationship is questioned in both directions, namely with respect to the manner in which value added tax affect intermediate consumption and in terms of the influence of intermediate consumption on value added tax revenue in the case of Romania. Given that a significant part of the corporate taxpayers have left the value added tax regime, intermediate consumption is considered instead of final consumption. The analysis is focused on a specific relationship in order to assess the general impact of indirect taxation on production capacity of the undertakings. Our findings reveal that there is not a direct relationship between intermediate consumption and value added tax revenue at the level of Romania despite a such relationship at the EU-28 level. Moreover, in the case of Romania a high volatility of intermediate consumption was found. Both the breakage between tax revenue and his tax base, and volatility of the tax base suggest an influence of hidden economy. For future concerns about tax policy development, a specific model for estimating and forecasting value added tax revenue should be developed for Romania. On the other hand, based on the findings of this study, a model can be developed to assess the impact of the hidden economy on the value added tax revenue.

Crude (i.e., unrefined) glycerol is the major by-product of biodiesel production, based on the homogeneous alkaline catalytic transesterification reaction. Currently, global biodiesel production capacity has been rising rapidly due to the overall growth of renewable energy demand. The amount of glycerol is increasing in parallel, and there is presently little market value for crude glycerol. In addition, disposing of this material via conventional methods becomes one of the major environmental issues and a burden for biodiesel manufacturers. Thus, utilization of purified glycerol in value-added applications such as food processing, cosmetics, soap and pharmaceuticals is critical to achieve economic scale of biodiesel production. In this paper, various pathways available to community-based biodiesel producers have been modeled to inform the decision-making process. A case study at Rochester Institute of Technology (RIT) was selected to evaluate the proposed system. Different pathways of utilizing crude glycerol were investigated, and economic feasibility of each pathway was analyzed. Purification of crude glycerol from waste cooking oil-based-biodiesel production was performed at small bench scale. Various recipes with different raw materials and purified glycerol as an ingredient were created for different kinds of saponification processes and applications. The resulting data from this preliminary assessment showed that producing biodiesel and high-quality soap is the most profitable option for RIT.
