“…Although the relationship between Mn and biomass was R 2 = 8928, even so, this was a good fit to line. This relationship has also been demonstrated in macronutrients as N and P [23,24]. These results showed that the accumulation of micronutrients is highly dependent on cucumber growth, regardless of the variety or even the climate effects.…”

Abstract:The control of micronutrient application in cucumber cultivation has great importance as they participate in many functions of metabolism. In addition, micronutrient application efficiency is fundamental to avoid periods of overconsumption or deficits in the crop. To determine micronutrient accumulation using a dynamic model, two cycles of Vitaly and Luxell cucumber crops were grown. During the development of the crop, micronutrient content (Fe, B, Mn, Cu, and Zn) in the different organs of the cucumber plant was quantified. The model dynamically simulated the accumulation of biomass and micronutrients using climatic variables recorded inside the greenhouse as inputs. It was found that a decrease in photosynthetically active radiation and temperature significantly diminished the accumulation of biomass by the cucumber plants. On the other hand, the results demonstrated that the model efficiently simulated both the accumulation of biomass and micronutrients in a cucumber crop. The efficiency evaluation showed values higher than R 2 > 0.95. This dynamic model can be useful to define adequate strategies for the management of cucumber cultivation in greenhouses as well as the application of micronutrients.

“…However, these techniques have many disadvantages, such as being time-consuming, costly and requiring significant space (Zhu et al, 2011;Meyer, 2012;Saeed and Sun, 2012). Techniques using combined biotechnological and engineering methods to remediate heavily polluted rivers have been attracting increasing attention in the environmental protection field (Arini et al, 2012;Sheng et al, 2012).…”

a b s t r a c tRiver pollution is becoming a serious problem worldwide. A field-scale experiment was undertaken to remediate a heavily polluted river using a combined engineering approach of aeration, microorganisms, biological aerated filtration, artificial biofilms and ecological floating beds. Prior to remediation, the river water was black, anoxic and highly sulfidic. With remediation, the chemical oxygen demand decreased from ∼250 to ∼50 mg L −1 , NH 4 + -N decreased from ∼27 to ∼4 mg L −1 , sulfide decreased from ∼3 to ∼0.3 mg L −1 , and total suspended solids decreased from ∼270 to ∼40 mg L −1 . At the same time, dissolved oxygen increased from ∼0.1 to ∼3.5 mg L −1 , and water clarity increased from ∼6 to ∼40 cm. Furthermore, the unpleasant odor emanating from the polluted river was also stopped, and local farmers have begun using the water for irrigation. This field-scale experiment thus indicates the potential usefulness of this combined engineering approach to remediate heavily polluted rivers.

“…In-situ remediation is a technique for effectively purifying polluted surface waters. In fact, many in-situ remediation techniques such as ecological floating beds and artificial wetlands have been widely used for remedying polluted surface waters and achieved satisfactory outcomes; the plant products processed may be further employed as food of animals and even human beings or processed into biogas, bio-fertilizer, and biomaterials [2,3]. However, these technologies have a range of unexpected deficiencies arising from low temperature, limited intake of plants, limited biomass concentration and low water transparency [4].…”

Two kinds of fillers were chosen to explore surface water remediation with a sequencing batch biofilm reactor (SBBR). By comparing SBBR with the plastic filling reactor (PFR), which was considered as the control group, the effectiveness of a filamentous bamboo reactor (FBR) for removing organic substances, nitrogen and phosphorous as well as biomass changes. Experimental results suggested that in using a FBR the average removal rates of COD Mn Рассмотрены два типа наполнителей для исследования рекультивации поверхностных вод с помощью последовательного биопленочного реактора (SBBR). При сравнении SBBR с реактором с пластиковым наполнителем (PFR), который рассматривался как контрольная группа, показана эффективность нитевидного бамбукового реактора (FBR) для удаления органических веществ, азота и фосфора, а также биомассы. Экспериментальные результаты показали, что при использовании бамбукового наполнителя в биопленочном реакторе средняя скорость удаления COD Mn , TN, NH 4 + -N and NO 3 -N выше, чем при использовании пластикового наполнителя. Несмотря на значительные преимущества перед PFR при удалении COD Mn , TN, NH 4 + -N and NO 3 -N, FBR не был достаточно эффективным для удаления ТР. Использование бамбуковых нитей в качестве носителей и источника углерода, их высокое содержание гидрофильных функциональных групп и обильная микробная фация способствовали эффективному восстанавлению воды. Вивчення біоплівки на основі ниткоподібного бамбука для біоремедіації поверхневих вод. Zhang Huifang, Cao Wenping, Sun Ling, Liu Hanhu.Розглянуто два типи наповнювачів для дослідження рекультивації поверхневих вод за допомогою послідовного біоплівкового реактора (SBBR). При порівнянні SBBR з реактором з пластиковим наповнювачем (PFR), який розглядався як контрольна група, показана ефективність ниткоподібного бамбукового реактора (FBR) для видалення органічних речовин, азоту і фосфору, а також біомаси. Експериментальні результати показали, що при використанні бамбукового наповнювача в біоплівковому реакторі середня швидкість видалення COD Mn , TN, NH 4 + -N and NO 3 -N вище, ніж при використанні пластикового наповнювача. Показано, що FBR недостатньо ефективний для видалення ТР. Використання бамбукових ниток в якості носіїв і джерела вуглецю, їх високий вміст гідрофільних функціональних груп і рясна мікробна фація сприяли ефективному відновленню води.
