Abstract
The fruits of Amomum kravanh, Citrus hystrix and Piper nigrum 'Kampot' are traditionally used as spices in Cambodian cuisine. In this study, the chemical composition of essential oils (EOs) and supercritical CO2 extracts from all three species was determined using GC-MS, with two columns of different polarity (HP-5/DB-HeavyWAX). Differences between the chemical profile of the EOs and CO2 extracts were observed for all species. The greatest difference was detected in A. kravanh EO containing mainly eucalyptol (78.8/72.6%), while the CO2 extract was rich in fatty acids (13/55.92%) and long-chain alkanes (25.55/9.54%). Furthermore, the results for the CO2 extract of this species differed, where tricosane (14.74%) and oleic acid (29.26%) were the main compounds identified when utilizing the HP-5 or DB-HeavyWAX columns, respectively. Moreover, the EO and CO2 extract from P. nigrum 'Kampot' fruits and the CO2 extract from C. hystrix fruit peel, containing respective amounts 34.84/39.55% (for EO) and 54.21/55.86% (for CO2 extract) of β-caryophyllene and 30.2/28.9% of β-pinene, were isolated and analyzed for the first time. Generally, these findings suggest that supercritical CO2 could potentially be used for the extraction of all three spices. Nevertheless, further research determining the most efficient extraction parameters is required before its commercial application.

Abstract
In this study, microalgal biomass waste (Chlorella regularis) was treated while simultaneously producing bioelectricity in a microbial fuel cell (MFC). Algal biomass was the sole electron donor and was enriched with easily biodegradable proteins (46%) and carbohydrates (22%). The generated power density was 0.86 W/m2 and the columbic efficiency reached ∼61.5%.The power generation could be further increased to 1.07 W/m2 by using a biomass waste concentration enhancement strategy with maximum chemical oxygen demand (COD) removal of ∼65.2%. Via direct comparison, the power generation and COD removal capability of the algal-fed MFC was close to that of the commercial acetate-fed MFC. The algae-fed MFC presented superior electrochemical characteristics that were attributed to the complicated composition of the biomass anolyte. It possessed a multiple anode respiring bacterial group and diverse microbial community. Hence, this study provides a new strategy for the utilization of microalgal biomass as a bioresource.

Identification of optimum fatty acid extraction methods for two different microalgae Phaeodactylum tricornutum and Haematococcus pluvialis for food and biodiesel applications. Anal Bioanal Chem 2017; 409:4659-4667.

Abstract
Microalgae have the potential to synthesize and accumulate lipids which contain high value fatty acids intended for nutrition and biodiesel applications. Nevertheless, lipid extraction methods for microalgae cells are not well established and there is not a standard analytical methodology to extract fatty acids from lipid-producing microalgae. In this paper, current lipid extraction procedures employing organic solvents (chloroform/methanol, 2:1 and 1:2, v/v), sodium hypochlorite solution (NaClO), acid-catalysed hot-water extraction and the saponification process [2.5 M KOH/methanol (1:4, v/v)] have been evaluated with two species of microalgae with different types of cell walls. One is a marine diatom, Phaeodactylum tricornutum, and the other a freshwater green microalga, Haematococcus pluvialis. Lipids from all types of extracts were estimated gravimetrically and their fatty acids were quantified by a HPLC equipped with Q-TOF mass spectrometer. Results indicated significant differences both in lipids yield and fatty acids composition. The chloroform and methanol mixture was the most effective extraction solvent for the unsaturated fatty acids such as DPA (C22:05), DHA, (C22:06), EPA (C20:05) and ARA (C20:04). While acid treatments improved the saturated fatty acids (SFAs) yield, especially the short chain SFA, lauric acid (C12:0), whose amount was 64% higher in P. tricornutum and 156% higher in H. pluvialis compared to organic solvent extractions.

Abstract
UNLABELLED Microalgae are a sustainable bioresource, and the biofuel they produce is widely considered to be an alternative to limited natural fuel resources. However, microalgae harvesting is a bottleneck in the development of technology. Axenic Chlorella vulgaris microalgae exhibit poor harvesting, as expressed by a flocculation efficiency of 0·2%. This work optimized the co-culture conditions of C. vulgaris and bioflocculant-producing bacteria in synthetic wastewater using response surface methodology (RSM), thus aiming to enhance C. vulgaris harvesting and lipid content. Three significant process variables- inoculation ratio of bacteria and microalgae, initial glucose concentration, and co-culture time- were proposed in the RSM model. F-values (3·98/8·46) and R(2) values (0·7817/0·8711) both indicated a reasonable prediction by the RSM model. The results showed that C. vulgaris harvesting efficiency reached 45·0-50·0%, and the lipid content was over 21·0% when co-cultured with bioflocculant-producing bacteria under the optimized culture conditions of inoculation ratio of bacteria and microalgae of 0·20-0·25, initial glucose concentration of <1·5 kg m(-3) and co-culture time of 9-14 days. This work provided new insights into microalgae harvesting and cost-effective microalgal bioproducts, and confirmed the promising prospect of introducing bioflocculant-producing bacteria into microalgae bioenergy production. SIGNIFICANCE AND IMPACT OF THE STUDY This work optimized the co-culture conditions of microalgae (C. vulgaris) and bioflocculant-producing bacteria (F2, Rhizobium radiobacter) in synthetic wastewater using response surface methodology, aiming to enhance C. vulgaris harvesting and lipid produced content. Bioflocculant-producing microbes are environmentally friendly functional materials. They avoid the negative effects of traditional chemical flocculants. This work provided new insights into microalgae harvesting and cost-effective production of microalgal bioproducts, and confirmed the promising prospect of introducing bioflocculant-producing bacteria into microalgae bioenergy production.
