Marine brown-algae are important edible seaweed in Japanese diets, because they are rich in nutritionally beneficial elements and dietary fiber as well for their umami-taste. In contrast to these benefits, they accumulate arsenic during their growth. To overcome this inconvenience, some appropriate pre-cooking processes are desired to reduce arsenic contents.

The present study aims to determine the role of the carbon source from mangroves to provide the organic matter in intertidal sediments by the stable isotopes approach. The present results suggested that mangroves are important in accumulating organic carbon and fine–grained sediments in the Tien Yen Bay, contributing important values to climate change mitigation and maintaining biodiversity in this area.

The microbial cells can store energy in the form of polyhydroxyalkanoates (PHAs) while the nutrient sources are exhausted but have an excess of carbon sources. Poly(3-hydroxybutyrate) (PHB) was known as one of the most common PHA. Currently, PHB is assessed as a potential alternative to petroleum-based plastics such as HDPE, PP.

In this study, Lythrum salicaria plant was tested in hydroponic culture to demonstrate its zinc accumulating capacity and tolerance to different zinc levels. Lythrum salicaria seedlings were grown in 10% Hoagland solution containing 0, 5, 10, 20, 30, 40, 50, 75, and 100 mg/L zinc, and 30 mg/L zinc with different pH levels (5, 6, and 7). Following this, the seedlings were harvested after 1st, 2nd, 4th and 7th days. Zinc caused significant decreases in the relative values of the mean root-shoot length and fresh weight of the plant (92 to 75%; 100 to 92%; 64.2 to 41.

A simple and sensitive modified electrode was fabricated with graphene via the drop-casting method and applied for the electrochemical detection of Sudan IV. Cyclic voltammetry (CV) was used to investigate the electrochemical behaviors of Sudan IV in phosphate buffer solution (PBS). The experimental conditions such as determining medium, scan rate, and accumulation time were optimized for the determination of Sudan IV.

The present article describes a method of determination of low antimony concentrations using a graphite furnace AAS technique after electrochemical preconcentration. A 2-electrode flow-through cell was developed with a working electrode made of gold-coated porous carbon and an accessory Pt electrode. This cell worked in online coupling with the graphite furnace atomizer. Accumulation occurred from the 6 M hydrochloric acid solution and 2M nitric acid was used to dissolve and transport antimony into the sampling loop. The sampling loop was placed on a 6-way valve.

Herein, an adsorptive stripping linear sweep voltammetric technique was described to determine spiramycin, a macrolide antibiotic, using a carboxylic multiwalled glassy carbon electrode modified with carbon nanotubes. The main principle of the analytical methodology proposed was based on the preconcentration of spiramycin by open-circuit accumulation of the macrolide onto the modified electrode surface. As a result of the adsorption affinity of spiramycin to the modified surface, the sensitivity of the glassy carbon electrode was significantly increased for the determination of spiramycin.

Polyhydroxyalkanoate (PHA) is stored as an important carbon and energy source in bacterial cells. For biomedical applications, gram-positive bacteria can be better sources of PHAs, since they lack outer membrane lipopolysaccharide. Although gram-positive Streptomyces coelicolor A3(2) has been indicated as a high potential PHA producer, phaC gene that encodes the key enzyme PHA synthase in the metabolic pathway is not determined in its genome.

Cereal grains, including wheat (Triticum aestivum L.), are major sources of food and feed, with wheat being dominant in temperate zones. These end uses exploit the storage reserves in the starchy endosperm of the grain, with starch being the major storage component in most cereal species.

In this chapter, physiological responses of oleaginous fungi such as, biomass production, substrate uptake, secretion of hydrolytic enzymes, and lipid accumulation with cellulose or starch as the organic carbon substrate were studied. Glucose, one of the simplest sugars, was also studied as a comparison study. M. rouxii, a known lipid and GLA producer (Ahmed et al., 2006), was used in this study.

The effect of different nitrogen sources on cell growth and polyhydroxyalkanoate (PHA) accumulation by halophilic bacterium strain Yangia sp. ND199 was investigated. The combination of 0.5 g/L potassium nitrate (KNO3) and 0.5 g/L yeast extract was shown to be good nitrogen source for cell growth and PHBV production by Yangia sp. ND199.

This study presents a new halophilic bacterial strain named Yangia sp. ND 218 which was isolated from the Giao Thuy mangrove, Nam Dinh Province, Vietnam which grew and accumulated PHA in a high salt medium. The possibility of designing an open (unsterile) fermentation process using Yangia sp. ND 218 was investigated.

The green microalga Dunaliella salina accumulates a high proportion of β-carotene during abiotic stress conditions. To better understand the intracellular flux distribution leading to carotenoid accumulation, this work aimed at reconstructing a carbon core metabolic network for D. salina CCAP 19/18 based on the recently published nuclear genome and its validation with experimental observations and literature data.

In the current context of eco-pollution, the substitute of conventional plastics with bioplastics is a big confront. On account of that, a non-growth associated PHB production study was conducted using Zobellella species under submerged fermentation process. As a result, Zobellella species showed the ability to accumulate 2.2g/L of PHB at pH 8. 0, temperature 37oC, salt concentration 2% in modified growth medium containing vitamins. Then, primary structural characterization of extracted polymer was conducted by FTIR analysis. The high intense peak was obtained at 1720.

The average concentration of particulate organic carbon (POC), dissolved organic carbon (DOC) and microbial biomass carbon (MBC) in organic manure plus inorganic fertilizer treatments (NP+S and NP+FYM) in 0–60 cm depth were increased by 64.9–91.9%, 42.5–56.9%, and 74.7–99.4%, respectively, over the CK treatment. Accumulation of crop residues and organic matter in the surface layer under conservation tillage creates favourable feeding conditions and also provides physical protection to various soil organisms, thereby increasing their abundance as well as diversity.
