“…Compared with conventional energy-intensive hydrogen production processes such as steam methane reforming, water electrolysis, and coal gasification, fermentative hydrogen production from biomass has significant benefits owing to the mild reaction conditions (Xia et al, 2015a). However, after dark fermentation the largest portion of energy remains in the form of soluble metabolic products (SMPs) such as volatile fatty acids (VFAs), alcohols, and lactic acids rather than in gaseous hydrogen (Cheng et al, 2016).…”

“…In contrast the low C/N ratios in many micro-algae species can cause high ammonia levels which inhibit the anaerobic fermentation process (Allen et al, 2013b). Thus, mixing carbon-rich macro-algae and nitrogen-rich micro-algae at a suitable C/N ratio as co-substrates will theoretically improve the fermentation performance (Xia et al, 2015a).…”

“…Microalgae carbon dioxide fixation systems are an environmentally friendly, energy-efficient, and cost-effective method for addressing the problem of global warming, which is mainly caused by the increase in atmospheric carbon dioxide (CO 2 ) produced by fossil fuel combustion [105,106]. Miyamoto et al have previously proposed a system for the conversion of algae biomass to H 2 using photosynthetic bacteria [107].…”

Natural anisotropic nanostructures occurring in several organisms have gained more and more attention because of their obvious advantages in sensitivity, stability, security, miniaturization, portability, online use, and remote monitoring. Due to the development of research on nature-inspired bionic structures and the demand for highly efficient, low-cost microfabrication techniques, an understanding of and the ability to replicate the mechanism of structural coloration have become increasingly significant. These sophisticated structures have many unique functions and are used in many applications. Many sensors have been proposed based on their novel structures and unique optical properties. Several of these bio-inspired sensors have been used for infrared radiation/thermal, pH, and vapor techniques, among others, and have been discussed in detail, with an intense focus on several biomedical applications. However, many applications have yet to be discovered. In this review, we will describe these nanostructured materials based on their sources in nature and various structures, such as layered, hierarchical, and helical structures. In addition, we discuss the functions endowed by these structures, such as superhydrophobicity, adhesion, and high strength, enabling them to be employed in a number of applications in biomedical fields, including cell cultivation, biosensors, and tissue engineering.

“…Biological hydrogen production is better than other traditional methods of production as it is green [7]. Aquatic algal biomass, which can be sourced from natural algal bloom or mass cultivation, is considered as a promising substrate for hydrogen fermentation [8]. Previous studies indicated that anaerobic sludge (AS) and microalgae were co-cultured to enhance the energy conversion and nutrients removal from starch waste water [9].…”

In this study, optimization of microwave (MW) pretreatment conditions for anaerobic digestion of green microalgae (Enteromorpha) is carried out by using response surface methodology (RSM). MW power, pretreatment time and liquid-solid ratio were selected as independent variables for optimization. The optimum conditions were achieved at MW power, pretreatment time and liquid-solid ratio of 656.92 W, 5.10 min and 33.63:1, respectively. From these optimum conditions, it was found that MW pretreatment power of about 600 W had better effect. An anaerobic digestion was carried out batch-wise with working volume, operating temperature and mixing rate as 250 ml, 37 °C and 150 rpm, respectively. Optimum conditions provide highest amount of COD and reducing sugar increase of 10,420 mg/L and 0.77-0.79 g/L respectively. The increase in COD and reducing sugar showed that the pretreatment has improved anaerobic digestion of microalgae. The peak biogas production amount of MW pretreated 20:1, 6 min group reached 244 mL whereas the control group only reached 188 mL in total.
