Antibacterial proteins in the serum hemolymph and hemocyte lysate supernatant of the banana prawn, penaeus merguiensis

Janjarus Watanachote; Suriyan Tankijjanukij; Chutiwan Dechsakulwatana (2008)

As invertebrates do not synthesize specific antibodies, a number of antibacterial proteins and lectins have been isolated from their serum hemolymph and hemocytes. Antibacterial activity in serum hemolymph and hemocyte ...
Carotenoid Production from Sponge-associated Bacteria Isolated in the Gulf of Thailand

Chutiwan Dechsakulwatana; Patcharee Thawornwiriyanun; Leena Suntornsuk; Worapot Suntornsuk (2009)

This research was aimed at identifying a sponge-associated bacterium that produces carotenoids and studying optimum conditions for carotenoid production. Bacterial identification was carried out by the determination of ...
Cyclic Tetrapeptides from Marine Bacteria Associated with the Seaweed Diginea sp. and the Sponge Halisarca Ectofibrosa

Chutiwan Dechsakulwatana; Wimolpun Rungprom; Eric R.O. Siwu; Lynette K. Lambert; Michael C. Barden; Udom Kokpol; Joanne T. Blanchfield; Masaki Kita; Mary J. Garson (2008)

A Pseudomonas sp. was cultured which was associated with the Japanese seaweed Diginea sp. Crude extracts prepared from this bacterial culture were found to inhibit the growth of other marine bacterial strains. From this ...
Identification of newly zeaxanthin-producing bacteria isolated from sponges in the Gulf of Thailand and their zeaxanthin production

Chutiwan Dechsakulwatana; Patcharee Thawornwiriyanun; Somboon Tanasupawat; Somkiet Techkarnjanaruk; Worapot Suntornsuk (2012)

Sponge-associated bacteria have been found to produce a variety of bioactive compounds including natural pigments. Here, we report the molecular identification of zeaxanthin-producing sponge-associated bacteria isolated ...
In-situ Observations of Symbionts on Medusae Occurring in Japan,Thailand, Indonesia and Malaysia

Chutiwan Dechsakulwatana; Khwanruan Srinui; Susumu Ohtsuka; Yusuke Kondo; Yocichi Sakai; Takeshi shimazu; Michitaka Shimomura; Tomoyuki Komai; Keisuke Yanagi; Toshihiko Fujita; Jun Nishikawa; Hiroshi Miyake; B.A. Venmathi Maran; Akio Go; Kazumitsu Nagaguchi; Shuhei Yamaguchi; Nova Mujiono; Fatimah Md. Yusoff; Mulyadi; Sutomo; Sumatt Putchakarn (2010)

During an ecological investigation on symbionts of medusae in Eastern and Southeastern Asian waters, seven species of hydro- and scypho-medusae were found to harbor a wide variety of invertebrates and fishes: the isopod ...
Isolation and killing activities of algicidal bacteria on a diatom Skeletonema sp. and a dinoflagellate Noctiluca scintillans in Thailand

Chutiwan Dechsakulwatana; Khwanruan Pinkaew; Wanchai Wongsudawan; Institute of Marine Science; Fukami Kimio (2006)

An attempt of this study is to isolate and to investigate the algicidal bacteria that can be against the harmful algal blooms (HAB) and have killing activity by which bacteria are associated with the events and kill their ...
Partial purification of lectin from hemolymph of Penaeus Merguiensis with antibacterial activity and bacterial clearance activity

Chutiwan Dechsakulwatana; Suriyan Tunkijjanukij; Janjarus Watanachote; Supawadee Poompuang; Sunanta Ratanapo (2007)

Lectins play relevant role in humoral defenses of invertebrates. The hemolymph of banana prawn, Penaeus merguiensis contains a lectains a lectin (PML). In an attempt to identify the lectin subunits and responsive proteins ...
Survival of Faecal Indicator Bacteria in Tropical Estuarine Waters (Bangpakong River, Thailand).

Chutiwan Dechsakulwatana; Ratiwun Onrassami; A.A. Bordalo (2002)

Aims: To investigate the survival of cultivable bacteria in the tropical Bangpakong estuary (Eastern Thailand) under different salinities and light conditions. Methods and Results: Dark and light microcosm experiments ...
