Abstract:

The brown alga Silvetia siliquosa (Tseng et Chang) Serrão, Cho, Boo & Brawly is endemic to the Yellow-Bohai Sea and southwestern Korea. It is increasingly endangered due to habitat loss and excessive collection. Here, we sequenced the mitochondrial (mt) and chloroplast (cp) genomes of S. siliquosa. De novo assembly showed that the mt-genome was 36,036 bp in length, including 38 protein-coding genes (PCGs), 26 tRNAs, and 3 rRNAs, and the cp-genome was 124,991 bp in length, containing 139 PCGs, 28 tRNAs, and 6 rRNAs. Gene composition, gene number, and gene order of the mt-genome and cp-genome were very similar to those of other species in Fucales. Phylogenetic analysis revealed a close genetic relationship between S. siliquosa and F. vesiculosus, which diverged approximately 8 Mya (5.7–11.0 Mya), corresponding to the Late Miocene (5.3–11.6 Ma). The synonymous substitution rate of mitochondrial genes of phaeophycean species was 1.4 times higher than that of chloroplast genes, but the cp-genomes were more structurally variable than the mt-genomes, with numerous gene losses and rearrangements among the different orders in Phaeophyceae. This study reports the mt- and cp-genomes of the endangered S. siliquosa and improves our understanding of its phylogenetic position in Phaeophyceae and of organellar genomic evolution in brown algae.

Abstract:

Temperature rise due to climate change have an impact on various ecosystems, including coastal ecosystems. Temperature rise also affects plant metabolism, such as carbon uptake. Macroalgae is the dominant community in the intertidal zone, and potential to absorb carbon. A series of experiments on several dominant macroalgae species from the south coast of West Java have been done to see the effect of temperature regime on carbon content. The treatment of temperatures of 24, 27, 30, and 33 °C was carried out for 72 hours against 6 macroalgae species representing Chlorophycae, Phaeophycea and Rhodophyceae to investigate carbon content. The results showed that the macroalgae of Phaeophyceae division showed higher carbon content in comparison to the macroalgae of the other divisions. The temperature that significantly affects chloropyll was 33 oC against all the species being tested.

Abstract:

The use of brown-macroalgae (Phaeophyceae) as an alginate source is very broad, covering the food and non-food industry, because of that it is necessary to know the safety of these natural resources, one of which is safe from heavy metal contamination. The purpose of this study was to determine heavy metals concentrations accumulated in several types of Phaeophyceae (brown macroalgae) as an alginate source from Malang Rapat waters, Bintan. The method used was descriptive non-experimental. The determination of the location of sampling was done by purposive sampling method. Samples were taken through free collection, identified species and measured of metal contamination concentrations for As, Cd, and Pb. The data obtained were analyzed descriptively. The results showed that Phaeophyceae found in Malang Rapat waters were Turbinaria conoides, Sargassum aquifolium, Padina australis, Hormophysa cuneiformis with each metal concentration contamination of As 13.95 to 23.30 µg.g-1 dry weight; Cd from 0.33 to 1.08 µg.g-1 dry weight and Pb from 4.72 to 9.92 µg.g-1 dry weight. This study showed that all metal contamination ranges in all Phaeophyceae were on the verge of the maximum limit set by the National Standardization Agency of Indonesia Indonesian (SNI) No 7387 of 2009 and National Agency of Drug and Food Control of RI (BPOM) Regulation No 5 of 2018 for dried macroalgae product so that Phaeophyceae from Malang Rapat waters - Bintan was not safe to be used as raw material for alginate source or other processed products of brown-macroalgae.

RESUMO O presente estudo tem por objetivo contribuir para o estudo de caracteres sub-celulares que poderão ser utilizados na taxonomia das Phaeophyceae filamentosas, fornecendo dados sobre a estrutura e ultra-estrutura das células vegetativas e do estágio reprodutivo plurilocular de H. mitchelliae. Para tanto, estudos de microscopia de luz e eletrônica de transmissão foram realizados. As células vegetativas e reprodutivas de H. mitchelliae são uninucleadas, revestidas por uma parede celulósica, outros polissacarídeos e proteínas. A presença de um núcleo por célula, a organização dos tilacóides nos cloroplastos, formando bandas com três tilacóides, dispostos longitudinalmente ao eixo maior da organela e ausência de tilacóide no pirenóide foram similares a outras Phaeophyceae. H. mitchelliae também exibiu características ultra-estruturais que estão geralmente associadas a outras espécies, de ordens menos avançadas de Phaeophyceae como a presença de um proeminente pirenóide, dictiossomos perinucleares e plasmodesmos. A morfologia e a organização dos cloroplastos, bem como a presença ou ausência de pirenóide são características importantes dentro das Phaeophyceae. A formação de um novo pirenóide, em estágio de diferenciação, foi observada nos cloroplastos das células vegetativas. Ambas as células apresentaram núcleo com um grande nucléolo, sugerindo uma alta atividade metabólica. Muitos corpos osmiofílicos, os fisóides, foram vistos no citoplasma das células vegetativas e reprodutivas. As células da estrutura plurilocular madura de H. mitchelliae diferiram das células vegetativas por apresentar tamanho reduzido, citoplasma denso e desprovidas de vacúolos.

Abstract:

Tulisan ini dibuat untuk mengetahui potensi, faktor pembatas, dan pengolahan rumput laut coklat (Phaeophyceae) sebagai pakan ayam petelur. Rumput laut coklat (Phaeophyceae) adalah rumput laut yang mengandung pigmen klorofil a, karotin, xanthofil dan fukosantin, pigmen yang dominan adalah fukosantin yang menutupi warna lainnya dan menyebabkan rumput laut ini kelihatan berwarna coklat. Rumput laut coklat memiliki potensi sebagai bahan pakan ayam petelur karena ketersediaan yang melimpah, tidak bersaing dengan kebutuhan manusia, mengandung zat-zat nutrisi, tidak bersifat toksik, kaya asam lemak omega 3, mengandung pigmen fukosantin, alginat dan fukoidan. Faktor pembatas penggunaan rumput laut ini, yaitu 1) Kandungan nutrisi dan kualitas: alginat tinggi, protein rendah, dan energi rendah; 2) Kandungan anti nutrisi: kadar garam tinggi dan phlorotannin; 3) Penanganan dan pengolahan: membutuhkan berbagai pengolahan khusus sebelum digunakan sebagai pakan ternak. Faktor-faktor pembatas tersebut dapat diatasi dengan perlakuan fisik (pencucian, pengeringan, autoklaf, perebusan dan freezing), fermentasi dan penambahan enzim dalam pakan sebagai upaya untuk meningkatkan ketersediaan zat nutrisi dan mendetoksifikasi senyawa antinutrisi. Rumput laut coklat (Phaeophyceae) memiliki potensi sebagai bahan pakan penyusun ransum ayam petelur.

Abstract:

Abstract Seaweeds cover a wide range of applications, e.g. as food supplements, in animal feed, as biofuels or as sources of bioactive compounds. The Greek coast in the East Mediterranean is rich in various seaweeds that remain unexploited because their chemical and nutritional content has not yet been characterized. In the present study, eight seaweeds belonging to the Rhodophyta, Ochrophyta (class Phaeophyceae) and Chlorophyta were biochemically characterized and evaluated as potential food sources. Total polyphenol content, antioxidant activity, fatty acids and elemental composition were measured. Acanthophora nayadiformis, Ceramium sp. (Rhodophyta), Codium fragile (Chlorophyta), Cystoseira foeniculacea and Gongolaria barbata (formerly Cystoseira barbata) (Ochrophyta, Phaeophyceae) had the highest phenolic content and strongest antioxidant activity. Both brown and red seaweeds were rich in minerals, with G. barbata, Dictyopteris polypodioides (formerly Dictyopteris membranacea) (Chlorophyta, Phaeophyceae) and A. nayadiformis being the richest in macro- and microelements. The low Na/K ratio in most seaweeds (0.03–3.49) and the high iron content of red and brown algae (1.01–52.40 mg 100 g−1 of wet tissue) make algal consumption an attractive option. Chlorophyta and Phaeophyceae had the lowest n-6/n-3 PUFA ratios, with α-linolenic acid being the most abundant n-3 PUFA. The green algae Codium fragile and Ulva lactuca had the highest oleic and docosahexaenoic acid content, respectively. Finally, Rhodophyta were the highest producers of eicosapentaenoic acid. The findings confirmed the nutritional value of all seaweeds, highlighting brown seaweeds Cystoseira foeniculacea, G. barbata, and D. polypodioides as potential sources for food supplements and candidate species for seaweed cultivation in Mediterranean coastal waters.

Abstract:

A revised checklist of marine benthic algae of the Commander Islands (Russian Pacific) is presented. It is based on the authors’ field collections. The list of algae of the area totals to 187 species (36 Chlorophyta, 38 Ochrophyta, class Phaeophyceae, and 113 Rhodophyta) of these 44 species (9 Chlorophyta, 8 Ochrophyta, class Phaeophyceae, and 27 Rhodophyta) are added to the previous checklists (Selivanova and Zhigadlova, 1997). We also confirm the presence of 5 species on the Islands that were absent in our earlier material but were recorded by other authors (Phycodrys amchitkensis, Mastocarpus papillatus, Lithothamnion sonderi, Odonthalia dentata, and Pleonosporium vancouverianum). The species list of the newly recorded algae contains information on their ecology, fertility, and distribution. The algal taxonomy and nomenclature are updated with new world data.

Abstract:

We report here the results of a survey of the phytobenthos of Boipeba Island, Bahia state, Brazil. Samples were collected during three periods (July 2007 and March and December 2012) in the intertidal regions of offshore reefs near the beaches at Ponta dos Castelhanos, Bainema, Moreré, and Tassimirim. A total of 159 taxa were identified: Rhodophyta (83), Chlorophyta (52), Heterokontophyta/Phaeophyceae (21), Cyanobacteria (02), and Magnoliophyta (01). The most representative orders were Ceramiales (Rhodophyta), Bryopsidales (Chlorophyta), and Dictyotales (Heterokontophyta/Phaeophyceae) with 30, 23 and 15 taxa respectively; vouchers were deposited in the herbarium of the Universidade Estadual de Feira de Santana (HUEFS). This work adds 150 new taxa to those already known for Boipeba Island, including Nitophyllum punctatum (Stackh. in With.) Grev., whose occurrence is now confirmed for the coast of Bahia. The number of species identified in this study was elevated in comparison with previous phytobenthos studies undertaken on Brazilian islands.

Abstract:

Non-conventional extraction of bioactive metabolites could provide sustainable alternative techniques to preserve the potency of antioxidants and antiviral compounds extracted from macro-algae. In this paper, we first reviewed the antioxidant and antiviral potential of the active metabolites that exist in the three known macro-algae classes; Phaeophyceae, Rhodophyceae, and Chlorophyceae, and a comparison between their activities is discussed. Secondly, a review of conventional and non-conventional extraction methods is undertaken. The review then focused on identifying the optimal extraction method of sulphated polysaccharide from macro-algae that exhibits both antiviral and antioxidant activity. The review finds that species belonging to the Phaeophyceae and Rhodophceae classes are primarily potent against herpes simplex virus, followed by human immunodeficiency virus and influenza virus. At the same time, species belonging to Chlorophyceae class are recorded by most of the scholars to have antiviral activity against herpes simplex virus 1. Additionally, all three macro-algae classes exhibit antioxidant activity, the potency of which is a factor of the molecular structure of the bioactive metabolite as well as the extraction method applied.

Abstract:

Seaweed, Sargassum wightii is a brown macroalgae (Phaeophyceae) rich in bioactive compounds such as fucoxanthin, flavonoids, sterols, sulfated polysaccharides, polyphenols, proteins and beta-carotene pigments. The purpose of the present review is to focus and discuss the usefulness of bioactive compounds of S. wightii to humans and animals as they exhibit diverse therapeutic activities like analgesic, anti-inflammatory, antioxidant, anti-cancer, anti-microbial, anti-tumor, immune-modulatory, anti-coagulant, hepatoprotective, anti-viral activities, etc. The present review clarifies the nutritional, therapeutic potential and health benefits of brown seaweed algae. Nowadays, attention is being paid on the use of seaweeds for human health, food, cosmetics, energy, fertilizer and in the field of aquaculture, poultry and other industries due to their nutritive value. It is being utilized in the wastewater treatments to reduce nitrogen and phosphorus-containing compounds. This review is an attempt to highlight the nutritional and commercial value of Sargassum wightii, due to its bioactive compounds related to health status and disease prevention in humans and animals. Key words: Bioactive compounds, Phaeophyceae, Seaweeds, Sargassum wightii

Abstract:

The present review outlines the history of the study of plasmodesmata in brown algae, describes their ultrastructure, which differs from that of other groups of algae and land plants, presents variants of localization of plasmodesmata in different members of Phaeophyceae – from a scattered location to arrangement into pit fields; the functions performed by plasmodesmata in the thalli of brown algae are listed. Possible prospects for further study of these structures are specified.
