Biodiesel from algae: challenges and prospects.

Algae are increasingly emerging as one of the most promising sustainable and long-term sources of biomass and oils for fuel, feed food and other co-products. What makes them so attractive are the large number and wide variety of benefits associated with how and where they grow. This review presents added values and recent developments in resource recovery from microalgae. The main focus was in the cultivation and application of microalgae on biofuel recovery. Nearly all these benefits stem from the fact that these plants have evolved over billions of years to produce and store energy in the form of oil, and they do this more efficiently than any other known natural or engineered process. The results show that the investment in a microalgae biomass project can be associated with various processes, which include: growth of microalgae, harvesting, dehydration and extraction of oils.

Coupling of Algal Biofuel Production with Wastewater

Metrics details. Microalgae have recently attracted considerable interest worldwide, due to their extensive application potential in the renewable energy, biopharmaceutical, and nutraceutical industries. Microalgae are renewable, sustainable, and economical sources of biofuels, bioactive medicinal products, and food ingredients. Several microalgae species have been investigated for their potential as value-added products with remarkable pharmacological and biological qualities. As biofuels, they are a perfect substitute to liquid fossil fuels with respect to cost, renewability, and environmental concerns. Microalgae have a significant ability to convert atmospheric CO 2 to useful products such as carbohydrates, lipids, and other bioactive metabolites.

In the present scenario, rapid industrialization and urbanization have led to a dramatic increase in the levels of various hazardous pollutants in the environment, and this creates a serious threat to humankind. Today, most of the energy production comes from fossil fuel combustion, which is the key source of CO2 emissions. Research studies show that the utilization of microalgae could be the best option for the production of renewable and sustainable energy and for the mitigation of CO2 emission. Production of biofuels from microalgae can be classified as solid biochar , liquid bioethanol, biodiesel, bio-kerosene , and gaseous biogas, bio-syngas, biohydrogen fuels. Algal lipids usually have a higher viscosity than petro-diesel; therefore, the transesterification process is required to decrease the viscosity of microalgal lipids before they can be combusted in the engines.

Prospects and Challenges in Algal Biotechnology

Depleting fossil fuel, soaring prices, growing demand, and global climate change concerns have driven the research for finding an alternative source of sustainable fuel. Microalgae have emerged as a potential feedstock for biofuel production as many strains accumulate higher amounts of lipid, with faster biomass growth and higher photosynthetic yield than their land plant counterparts. In addition to this, microalgae can be cultured without needing agricultural land or ecological landscapes and offer opportunities for mitigating global climate change, allowing waste water treatment and carbon dioxide sequestration. Despite these benefits, microalgae pose many challenges, including low lipid yield under limiting growth conditions and slow growth in high lipid content strains. Biotechnological interventions can make major advances in strain improvement for the commercial scale production of biofuel.

Sustainable Third Generation Microalgae Based Biodiesel Production : Challenges and Opportunities Abstract: Since from centuries humans are utterly relied on the continual use of fossil for fulfilling daily desires, however with the increasing population fossil fuels are decreasing rapidly. Fossil fuels aren't thought as sustainable source of energy.

Microalgae have gained enormous consideration from scientific community worldwide emerging as a viable feedstock for a renewable energy source virtually being carbon neutral, high lipid content, and comparatively more advantageous to other sources of biofuels. Although microalgae are seen as a valuable source in majority part of the world for production of biofuels and bioproducts, still they are unable to accomplish sustainable large-scale algal biofuel production. Wastewater has organic and inorganic supplements required for algal growth. The coupling of microalgae with wastewater is an effective way of waste remediation and a cost-effective microalgal biofuel production.

We apologize for the inconvenience...

Tailoring Microalgae for Efficient Biofuel Production

Сьюзан подбежала к. - Коммандер. Стратмор даже не пошевелился. - Коммандер. Нужно выключить ТРАНСТЕКСТ. У нас… - Он нас сделал, - сказал Стратмор, не поднимая головы.

 Я думал, вы из городского… хотите заставить меня… - Он замолчал и как-то странно посмотрел на Беккера.  - Если не по поводу колонки, то зачем вы пришли. Хороший вопрос, подумал Беккер, рисуя в воображении горы Смоки-Маунтинс.

Potential of Microalgal Biodiesel: Challenges and Applications

 - Здесь мы в безопасности. Нам нужно поговорить. Если Грег Хейл ворвется… - Он не закончил фразу. Сьюзан потеряла дар речи. Он пристально посмотрел на нее и постучал ладонью по сиденью соседнего стула.

 Пожалуйста, сядь, Сьюзан. У нее был совершенно растерянный вид. - Сядь, - повторил коммандер, на этот раз тверже.

Странно, но его очки ничуть не пострадали. Странные очки, подумал Беккер, увидев проводок, который тянулся от ушных дужек к коробочке, пристегнутой к брючному ремню. Но он настолько устал, что ему было не до любопытства. Сидя в одиночестве и собираясь с мыслями, Беккер посмотрел на кольцо на своем пальце. Зрение его несколько прояснилось, и ему удалось разобрать буквы.

Стратмор опустился на колени и повернул тяжелый винтовой замок. Теперь крышку не поднять изнутри. Подсобка компьютера надежно закрыта. Ни он, ни Сьюзан не услышали тихих шагов в направлении Третьего узла. ГЛАВА 60 По зеркальному коридору Двухцветный отправился с наружной террасы в танцевальный зал.

Он успел выскользнуть до того, как Стратмор захлопнул крышку люка, и ему хватило сил самому открыть двери. Сьюзан приходилось слышать, что сильный страх парализует тело, - теперь она в этом убедилась. Ее мозг мгновенно осознал происходящее, и она, вновь обретя способность двигаться, попятилась назад в темноте с одной только мыслью - бежать.

Хейл очень опасен.
