“…A highly significant difference was detected in hand-beaten pulp (M= 2.22, SD= 0.5) and blended pulp (M= 0.802, SD= 0.414) of Halophila spinulosa, t(8)= 4.901, p= 0.001. High beating of pulp can improve the mechanical strength of paper (Seo et al 2010). For breaking length (Table 6), there was a highly significant difference in beaten pulp (M= 2.43, SD= 0.22) and blended pulp (M= 1.09, SD= 0.54) of Halophila spinulosa, t(8)= 4.068, p= 0.004.…”

“…A previous study on red algae, Gelidium corneum (2.29 kN/m, 3.84 km) and Gelidium amansii (1.86 kN/m, 3.01 km) indicated comparable tensile strength and breaking length value, respectively, with seagrass species of this present study. Thus, both materials may be suitable for many types of paper such as printing paper, filter paper, and edible paper (Seo et al 2010).…”

Marine angiosperms could inevitably offer considerable potential resources for their fiber, yet little research has been conducted, especially in Malaysia. Fiber characteristics of five species of seagrass -Enhalus acoroides, Cymodocea serrulata, Thalassia hemprichii, Halophila ovalis, and Halophila spinulosa -were evaluated. Fiber dimensions were studied to determine slenderness ratio, flexibility coefficient, Runkel's ratio, and Luce's shape factor species selection. The seagrass species have the potential in papermaking production as they possessed slenderness ratio >33 (98.12 to 154.08) and high Luce's shape factor (0.77 to 0.83); however the species exhibited low flexibility coefficient <50 (30.07 to 35.18) and >1 Runkel's ratio (1.11 to 1.60), which indicate rigid fiber. The five seagrass species have high cellulose >34% (40.30 to 77.18%) and low lignin content <15% (5.02 to 11.20%), which are similar to those encountered in non-wood plant species. Handmade paper sheet of Enhalus acoroides using pulp subjected to mechanical blending exhibited the highest tensile strength (4.16 kN/m) compared to hand-beaten pulp (3.46 kN/m). The highest breaking length (3.43 km) was achieved by a paper sheet of Thalassia hemprichii using hand-beaten pulp. Based on their physical and chemical composition properties, seagrass have potential as sources of fibrous material for handmade papermaking.

“…Gelidium is economically important as food, and one of the most promising agar sources in rhodophytes. It has recently been used for industrial paper pulp production in Korea (Seo et al 2010). However, identification of individual Gelidium specimens is notoriously difficult because of the high degree of morphological variation, particularly in the smaller and medium-sized species (Dixon and Irvine 1977a).…”

The taxonomic distinctiveness and cosmopolitan distributions of the red algae Gelidium crinale and G. pusillum remain unclear. Both species were first described in Devon in southwestern England; namely in Ilfracome for G. crinale and Sidmouth for G. pusillum. We analyzed mitochondrial cox1 and plastid rbcL sequences from specimens collected in East Asia, Australia, Europe and North America. In all phylogenetic analyses of cox1 and rbcL sequences, G. crinale was distinct from congeners of the genus. The analyses also revealed a sister relationship with the G. coulteri and G. capense clade. Nineteen cox1 haplotypes were identified for G. crinale, and they were likely geographically structured. Despite the distinctiveness in both cox1 and rbcL datasets, the sister relationship of G. pusillum in the genus was not resolved. Our cox1 and rbcL datasets indicate that G. crinale is a cosmopolitan species, found in East Asia, Australia, Europe and North America, while the distribution of G. pusillum is restricted to Europe and Atlantic North America. Our results suggest that infraspecific classification of G. pusillum may be abandoned.Key Words: cox1; distribution; Gelidium crinale; Gelidium pusillum; phylogeny; rbcL INTRODUCTIONGelidium Lamour. is composed of approximately 127 described species distributed globally along tropical, subtropical, and artic shorelines (Freshwater and Rueness 1994, Shimada et al. 2000, Millar and Freshwater 2005, Kim et al. 2011, in press, Guiry and Guiry 2012. Members of the genus can be the most abundant organisms within intertidal algal assemblages. Gelidium is economically important as food, and one of the most promising agar sources in rhodophytes. It has recently been used for industrial paper pulp production in Korea (Seo et al. 2010). However, identification of individual Gelidium specimens is notoriously difficult because of the high degree of morphological variation, particularly in the smaller and medium-sized species (Dixon and Irvine 1977a).Gelidium crinale (Hare ex Turner) Gallion and G. pusillum (Stackhouse) Le Jolis, which are small and morphologically diverse, are among the most difficult species to identify in red algae, and their distributions are unclear. These species are traditionally recognized as two distinct species (Feldmann and Hamel 1936, Silva et al. 1996), and Womersley and Guiry (1994 found a difference between the types of G. crinale and G. pusillum. On the contrary, G. crinale and G. pusillum were merged by Irvine (1977a, 1977b). Seven to nine varieties or formas have been described in each of G. crinale and G. pusillum (Silva et al. 1996, Guiry andGuiry 2012). The name G. pusillum is commonly used for any small tuft-forming Gelidium (Silva et al. 1996). Although G. crinale and G. pusillum are considered as the most widely distributed species in the genus AlgaeBase (Guiry and Guiry 2012), the occurrence -42-822-9690 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommo...

“…The red alga, Gelidium J.V. Lamouroux has been prepared for the production of paper in which the waste products have been renewed into bioethanol (Seo et al 2010). Also, green algae of Ulva spp., with a highgrade polysaccharide, Ulvan (Lahaye and Ray 1996) have been used in the production of ethanol and methane (Adams et al 2009).…”

The world seems to be raising its energy needs owing to an expanding population and people's desire for higher living standards. Diversification biofuel sources have become an important energy issue in recent times. Among the various resources, algal biomass has received much attention in the recent years due to its relatively high growth rate, its vast potential to reduce greenhouse gas (GHG) emissions and climate change, and their ability to store high amounts of lipids and carbohydrates. These versatile organisms can also be used for the production of biofuel. In this review, sustainability and the viability of algae as an up-coming biofuel feedstock have been discussed. Additionally, this review offers an overview of the status of biofuel production through algal biomass and progress made so far in this area.
