Irregular Magnetic Susceptibility Pattern of Iron Sand from Pasia Jambak Beach, Pasia Nan Tigo, Padang, Indonesia

Nocardioides basaltis sp. nov., isolated from black beach sand.

A novel Gram-positive, aerobic, short-rod-shaped bacterium, designated strain J112T, was isolated from black sand collected from Soesoggak, Jeju Island, Korea. The strain was found to be oxidase-negative and catalase-positive. Cells grew at 10-37 degrees C, at pH 5.5-8.0 and with 1-10 % NaCl. Growth occurred on marine agar but not on R2A or trypticase soy agar. A phylogenetic analysis based on ...

Pseudomonas sabulinigri sp. nov., isolated from black beach sand.

A novel Gram-negative, aerobic, motile, short rod-shaped bacterium, designated J64T, was isolated from black sand collected from Soesoggak, Jeju Island, Korea. Cells grew at 4-37 degrees C, at pH 5.5-10.0 and with 0-10 % NaCl. The strain was found to be oxidase- and catalase-positive. Phylogenetic analyses showed that strain J64T belongs to the genus Pseudomonas, forming a monophyletic group wi...

Hermaphroditism in the white spot grouper Epinephelus coeruleopunctatus (Pisces: Serranidae) harvested from Padang City waters, Indonesia

The objective of the present study was to determine the length (mm) for sex transformation of hermaphroditism in white spot grouper Epinephelus coeruleopunctatus as a basis for developing breeding technology. Fish sampling was carried out between April and October 2013 in Padang City waters, Indonesia. A total of 56 white spot groupers were recorded during the study; of these 22 were male, 28 f...

Antimicrobial Susceptibility of Staphylococcus aureus Isolated from Recreational Waters and Beach Sand in Eastern Cape Province of South Africa

Background: Resistance of Staphylococcus aureus to commonly used antibiotics is linked to their ability to acquire and disseminate antimicrobial-resistant determinants in nature, and the marine environment may serve as a reservoir for antibiotic-resistant bacteria. This study determined the antibiotic sensitivity profile of S.aureus isolated from selected beach water and intertidal beach sand i...
