Actinomycetes isolated

New antimicrobials are urgently needed to combat the threat of multidrug-resistant bacteria worldwide. Our study aimed to access the antimicrobial and cytotoxic profiles of endophytic actinomycetes associated with Cinnamomum cassia Presl taken from a mountainous region in the Northwest of Vietnam.

Endophytic microbes of medicinal plants are known to involve the synthesis of several bioactive compounds, which promote plant growth and resistance to diseases. In order to investigate endophytes in the important medicinal plant Catharanthus roseus, 16 endophytic microorganism strains were isolated from root samples of C. roseus var. roseus and C. roseus var. ocellatus naturally growing in coastal areas of Nha Trang, Vietnam.

The number and distribution of actinomycetes are very different in 10 species. In this study, 114 endophytic actinomycetes were isolated from 10 mangrove species in Giao Thuy, Nam Dinh: of which 44 strains were from their fruits, 40 from leaves, 21 from roots; 5 from trunks and 4 from flowers.

In this study we examined diversity and activities of some actinomycetes isolated from mangroves in Giao Thuy, Nam Dinh Province. The distribution of actinomycetes in soil is strongly affected by external factors. Extra-cellular enzyme producing ability of mangrove actinomycetes is very high, particularly the ability of producing cellulase degrading filter paper (122/128 strains), CMC (110/128 strains), protease (83/128 strains) and amylase (78/128 strains).

The objective of the present investigation was to isolate and identify the antimicrobial activity showing actinomycetes associated with sponges. Sponges such as Acanthella klethra, Theonella cylendrica, Helicona sp., Auletta sp., and Callyspongia sp. were collected at Sangumal, in Rameswaram island, Ramanathapuram District, Tamil Nadu, India. Isolates of 22 actinomycetes were isolated from sponges. Isolates No. 16 showed high antibacterial and antifungal activity and the isolate was identified as Streptomyces sp.

A new emerged lethal disease that termed EMS (Early Mortality Syndrome) or AHPNS (Acute Hepatopancreatic Necrosis Syndrome) caused by Vibrio parahaemolyticus had been added to list of shrimp diseases during last recent years. However, there are no currently available methods to treat EMS.
