Adzuki bean (Vigna angularis) is a traditional legume crop that plays a crucial role in the sustainability of both agricultural systems and in the food protein supply. As adzuki bean has been used for thousands of years in China as traditional Chinese medicine and foods, it has a great potential to be drug candidate or functional food materials. Adzuki is a good source of essential fatty acids, fiber, minerals and phytochemicals such as polyphenols and phytates. Legumes are nitrogen-fixing systems that have long been used for biological nitrogen fixation in agriculture. Biologically fixed nitrogen of adzuki beans can be yielded so that the hazards of the chemical fertilizers can be reduced. Because of the growing requests for plant production, especially protein and oils and also decrease the economic and environmental pressure on agro-eco systems, it emerges that grain legumes, adzuki bean included would play a major role in future cropping systems and sustainable agriculture. Legumes, especially those which have various medicinal effects can help to restore soil organic matter and reduce pests and diseases problems, and they may lead to more soil fertility. Adzuki beans have considerable potential globally to be a functional food for health promotion and diseases prevention in not only Asian countries, but also other parts of the world.
Changes of photosynthetic pigment content in lichens collected from urban and rural localities in Bursa province

In this study, contents of photosynthetic pigment in foliose Melanelixia subaurifera, Parmelia sulcata and fruticose Evernia prunastri, Ramalina farinacea were compared. Lichen species were collected from five localities in Bursa. Chlorophyll a, chlorophyll b, total chlorophlly, total carotenoid contents (mg/g), chlorophyll a/b ratio, total carotenoid/total chlorophyll ratio and phaeophytinization (OD435/OD415) ratio in the lichen extracts were differently determined between localities. These changes were found statistically significant (p≤0.05). The chlorophyll degradation rate at the localities in urban environments is determined to be higher than in the natural environment. It was observed that the air quality exposure ratio was related to the lichen morphology and thus the fruticose lichen species were more sensitive than foliose.
Evaluation of perspectives on ecotourism of Bursa Uludağ University agricultural faculty students
(Bursa Uludağ Üniversitesi, 2019-08-06) Erdoğan, Mehmet Akif; Turhan, Şule; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarım Ekonomisi Bölümü.
Ecotourism has emerged as the necessity of sustainable tourism and it is a formation that considers the welfare of the people living in rural areas. It is important to transfer the natural, cultural and historical legacies inherited from the past to the next generations. The contribution of the income distribution and the economy of the country is also an important fact. For this reason, all ecotourism activities should be implemented in accordance with the principles attached and a positive perception should be conveyed to the people. The aim of this study is to reveal the perspectives of university students on ecotourism, to determine their demographic characteristics and to give an idea about how to proceed. The students in the research area reported that their community was not sufficient for ecotourism. In addition, students' level of awareness on this subject was found to be low. In order to raise awareness of young people and all individuals on this issue, student communities should be strengthened and joint projects should be realized with the university.
Microorganisms based biological agents in wastewater treatment and agriculture: Potential use and benefits
(Bursa Uludağ Üniversitesi, 2019-08-21) Djadouni, Fatima
Human activities and population growth have placed the environment under increasing stress. Furthermore, indiscriminate use of natural resources is accompanied by increased local and global pollution levels, which are reflected in imbalances in our ecosystems. The generation of large quantities of wastewater with a high organic content and toxicants is one obvious product of excessive consumption. It has been known for many years that environmental discharges of high loads of organic matter can result in oxygen depletion in receiving waters due to stimulated microbial activity. This oxygen depletion and the presence of trace toxicants found in wastes also negatively influence ecosystems, including reduced biodiversity and environmental health. Therefore, negative environmental impacts have driven our need to understand the effect of pollution on water bodies and develop proper measures to reduce discharges, including treatment processes. Different technologies are available to treat wastes. However, biological wastewater treatment methods are most valuable because their economic benefits are high, especially when coupled with waste stabilization and resource recovery.
Removal of nitrate from groundwater using a hydrogen-based membrane biofilm reactor: The effects of hydrogen pressure and hydraulic retention time
(Bursa Uludağ Üniversitesi, 2019-09-10) Cuci, Yakup; Taşkın, Elif Gamze; Bursa Uludağ Üniversitesi/Fen Bilimleri Fakültesi/Çevre Mühendisliği Bölümü.
The membrane biofilm reactor (MBfR) is a novel system that uses membranes to supply dissolved gas directly to a biofilm growing on the membrane surface. In this study, hydrogen-based MBfR was used to remove nitrate from groundwater. The continuous flow MBfR reactor was operated under varying hydrogen (H2) pressures and hydraulic retention times (HRT) at constant nitrate concentration of 10 mg L -1 over 81 days with nitrate containing simulated groundwater. The study was composed two parts. In the first part of the study, the effect of H2 pressure on nitrate removal was investigated. The results showed that nitrate reduction rate improved as H2 pressure was increased from 2 to 5 psi, and over 98% of total nitrogen removal rate was achieved. In the second part of study, effect of HRT on nitrate removal was investigated under 5 psi H2 pressure. Our results showed stable nitrate removals under varying HRTs and decreasing HRT from 12 h to 1 h did not adversely affect the reactor performance, however, 0.5 HRT adversely affected the nitrate removal performance. The maximum nitrate removal flux of 3.01 g NO3 (0,659 g NO3) was reached. This research showed that H2 based MBfR is effective for removing nitrate from the contaminated groundwater.
Sustainable agriculture and soybean, a legume in traditional Chinese medicine with great biological nitrogen fixation
(Bursa Uludağ Üniversitesi, 2019-06-10) Shahrajabian, Mohamad Hesam; Sun, Wenli; Cheng, Qi
China is the home of the soybean. Traditional Chinese Medicine is a natural and organic health care system which view the body as a complex network of interconnected parts. The most important health benefits of soybeans are improving metabolic activity, health weight gain, anti-cancer potential, boost heart health, relieve menopausal symptoms, boost digestion, improve bone health, prevent birth defects, improve circulation, control diabetes and relieve sleep disorders. Soybeans can clear heat, detoxify, ease urination, lubricate lungs and intestine, provides an excellent protein food. In soybean, atmospheric nitrogen (N2) fixation happens in the nodules, nodules grow in the roots that are produced by N2-fixing rhizobial bacterias and most of these bacteria belong to the genera of Bradyrhizobium, Mesorhizobium, Rhizobium and Sinorhizobium. With the world’s increasing dependence on agriculture to feed its population, the use of reduced nitrogen derived from energy provided by fossil fuels is not likely to be sustainable. The key to future sustainable agriculture is to utilize the fundamental knowledge of the process of symbiotic nitrogen fixation in association with other agricultural crops to benefits an increasing world population. Food therapy of traditional Chinese medicine aims to maintain balanced nutrition through diet.
