BIOACTIVE COMPOUND FROM MICROALGAE AND ITS FUTURE PROSPECT. Microalgae biomass is potential to be used in various fields, one of which is as a producer of bioactive compounds. Bioactive compounds from microalgae can be used extensively in the pharmaceutical industry, cosmetic’s raw materials, food flavouring substances, and functional food ingredients. In terms of health, the bioactive compounds have the potential as antioxidants, antiviral, antibacterial, anti-fungal, anti-inflammatory, anti-tumor, and prevent the effects of malaria, but the potential for microalgae’s bioactive compound has not been explored well if compared to the production of terrestrial plants. Some examples of the bioactive compounds that have been used are carotenoid groups such as lutein, β-carotene, astaxanthin and fucoxanthin; fatty acid groups such as EPA and DHA; and also some toxin compounds such as domoic acid. To obtain the optimum yield of bioactive compounds, it requires the right method in biomass production, compound extraction, compounds isolation and compounds identification. While testing the activities, it is necessary to do some assays such as antioxidan, antibiotic, antiviral and anticancer assay. The development of the technology can improve the potential use of microalgae to synthesis its bioactive compounds.

Modern consumers are much aware of potential health benefits of food and food ingredients. The food industry has been constrained to develop new products with improved sensory, nutritive and functional characteristics. In this work a potential use of English (Quercus robur) and Turkish oak (Quercus cerris) kernels as functional food components was estimated. Volatiles from native and roasted kernels were isolated using continuous hydro distillation with CH2Cl2 and analyzed with GC/MS. Coffee-like beverages were prepared from roasted kernels of both species and a sensory assessment was conducted. In the native samples the main compounds were beta-eudesmol and palmitic acid (39.9 and 24.9%, respectively) in Q. robur, and palmitic acid (53.8%) in Q. cerris. In the roasted samples the main compounds were furans: furfural (51.7 and 60.6%) and 5-methyl-furfural (8.6 and 9.4%, respectively). Coffee-like beverages from roasted oak samples were evaluated for sensory properties gaining high scores for appearance, with satisfying taste and fullness. The presented results, along with previous findings on substantial antioxidant and antiradical activities of English and Turkish Oak kernels, draw attention to these easy available, cheap, but neglected native raw materials as valuable functional food components. Further investigations on this matter are warranted.

Leucaena leucocephala (lmk.) de Wit) (leed tree) seeds have been fermented by Indonesian as a traditional food which is called tempeh. The fermentation products of legume seeds are good functional foods, since they contain many bioactive compounds. The objective of this study was to determine the bioactive compound contents of fermented lead tree seed, such as total phenolic, ascorbic acid, β-carotene and a-tocopherol. Antioxidant activity testing was carried out using the thiobarbituric acid reactive substances (TBARS) method. Analysis of total phenolics, ascorbic acid, β-carotene and a-tocopherol were carried out using the folin-ciocalteu method, iodine titration, spectrophotometry and iron (III) chloride-thiocyanate, respectively. Rhizopus oligosporus was used to ferment lead tree seeds for 0, 1, 2, 3 and 4 days. Fermented leed tree seed powder was extracted with petroleum ether followed by ethanol. In comparison to unfermented leed tree seed powder, the β-carotene and a-tocopherol of the fermented seed powder increased. The greatest enhancement of β-carotene and a-tocopherol contents were observed at day 2 of fermentation. The highest antioxidant activities of fermented leed tree seeds were also obained at day 2 of fermentation with 55.55±4.59 and 74.46±3.49% inhibition in petroleum ether and ethanol extracts, respectively. The results show that lead tree seed tempeh has high antioxidant activity due to the bioactive compounds contains, such as  phenolics, β-carotene and a-tocopherol. Therefore, leed tree seed tempeh could be used for possible commercial production of functional food to alleviate oxidative stress.

<p>Bioactive compounds (phenols, tannins, flavonoids, essential oils, curcumin, saponins, phyllanthin) have the ability as an antibacterial or antifungal. Feed additives are feed raw materials that do not contain nutrients, however, it may increase productivity, quality of livestock products (meat, eggs, milk, skin, feathers), the feed efficiency and to improve animal health or resistance of disease. Feed additives that are widely used in the livestock industry include antibiotics, antioxidants, antifungals, emulsifiers, and binders. The aim of using antibiotics is to reduce the population of pathogenic microbes or disturbing microbes in the digestive tract. Antibiotics have been banned for used because it can cause resistance to pathogenic bacteria or intestinal microflora which has a negative impact on consumers. To improve feed efficiency in poultry and to produce higher quality products, healthy and safe for consumption, the antibiotic could be replaced with plant bioactive compound. The aims of this review is to describe the role of plant bioactive compounds as feed additive to replace antibiotic for chickens. Some of plant bioactive substances that can be used as feed additives include phenols, curcumin, saponins, tannins, phenols, flavonoids, alkaloids.

Numerous studies have demonstrated the availability of high-quality bioactive compounds in food along with their determination and quantification techniques. Many of these identified compounds have been claimed to possess health benefits such as anti-inflammatory, anti-cancer, antioxidant, anti-allergic, anti-fungal, antimicrobial and cardioprotective spasmolytic properties. However, mere presence of these compounds does not directly correlate with their potential health effects upon consumption. Since any food consumed does not reach the blood stream in the original form and as they are broken down to various compounds it is mandatory to consider their bioavailability and metabolism that takes place upon absorption. Furthermore, the efficacy of these bioactive compounds depends on various factors including the dosage, food matrix and stability of the compound during metabolism. Various bioavailability studies indicate that the parent bioactive compound is broken into various metabolites via oxidation, dehydroxylation, de-esterification, hydrolysis, carboxylation, α- and β-oxidation processes inside the human body. Therefore, this leads to an interesting conundrum that whether the proposed health effects are due to the parent bioactive compound or due to the metabolites formed during absorption. Some details in relation to the metabolism and metabolites of food bioactives are presented in this contribution.

Algae biomass is considered as an alternative raw material for the production of biofuels. The search for new types of raw materials, including high-energy types of microalgae, remains relevant, since the share of motor fuels in the structure of the global fuel and energy balance remains consistently high (about 35%), and the price of oil is characterized by high volatility. The authors have considered the advantages of microalgae as sources of raw materials for fuel production. Biochemical and thermochemical conversion are proposed as technologies for their processing. This paper presents the results of the study of the pyrolysis of the biomass of clonal culture of blue-green microalgae / cyanobacteriumArthrospira platensis rsemsu 1/02-Pfrom the collection of the Research Laboratory of Renewable Energy Sources of the Lomonosov Moscow State University. An experiment to study the process of pyrolysis of microalgae biomass was carried out at the experimental facility of the Institute of High Temperatures RAS in pure nitrogen grade 6.0 to create an oxygen-free environment with a linear heating rate of 10 ºС / min from room temperature to 1000 ºС. The whole process of pyrolysis proceeded in the field of endothermy. The specific amounts of solid residue, pyrolysis liquid and gaseous products were experimentally determined. As a result of the pyrolysis of microalgae biomass weighing 15 g, the following products were obtained: 1) coal has the mass of the solid residue is 2.68 g, or 17.7% of the initial mass of the microalgae (while 9.3% of the initial mass of the microalgae remained in the reactor); 2) pyrolysis liquid – weight 3.3 g, or 21.9% of the initial weight; 3) non-condensable pyrolysis gases – weight 1.15 l. The specific volumetric gas yield (the amount of gas released from 1 kg of the starting material) was 0.076 Nm3/ kg. The analysis of the composition and specific volume yield of non-condensable pyrolysis gases formed in the process of pyrolysis, depending on temperature. It is shown that with increasing temperature, the proportion of highcalorie components of the gas mixture (hydrogen, methane and carbon monoxide) increases. The calorific value of the mixture of these gases has been estimated.
