Actinobacteria strains

Developing new biofertilizers has been an area of great interest in modern agriculture. This study focused on actinobacteria possessing high chitinase activity, biofilm formation, plant growth promotion, and antifungal activity. Two chitinolytic actinomyces strains, YSS-3.3 and YWS-5.1, were isolated from soil and chitin flake samples collected from Yok Don National Park in the Central Highlands, Vietnam.

A total of 17 endophytic actinomycete strains were obtained from 6 medicinal plants of Mizoram, Northeast, India. 16S rRNA results showed 13 (73.3%) of the isolates belonged to the genus Streptomyces, 2 (13.3%) were Nocardiopsis, 1 (6.6%) were Tsukamurella tyrosinosolvens and 1 (6.6%) Actinobacteria bacterium. The highest number of endophytic actinomycetes was isolated from root tissue of Mikania micrantha Kunth. WI. (29.4%) followed by stem of Mikania micrantha Kunth. WI. and rhizome of Costus speciosus (J. Konig).

We screened 10 Actinoplanes and 14 Dactylosporangium strains to investigate the biocatalytic ability of two genera of the Micromonosporaceae family. Two Actinoplanes strains (A. ferrugineus NBRC15555 and A. missouriensis NBRC102363) exhibited good growth when cultured in 228 and 231 media, as did two Dactylosporangium strains (Dactylosporangium sp. NBRC101297 and Dactylosporangium sp. NBRC101730) when cultured in 227 and 266 media. The stereoselective reduction of various carbonyl compounds using these four strains was therefore investigated.

Salicornia europaea L. as an underutilized saline-tolerant plant inhabited by endophytic diazotrophs
Despite the great interest in using halophyte Salicornia europaea L. as a crop in extreme saline habitats, little is known about the role played by associated endophytic bacteria in increasing tolerance of the host-plant to nutrient deficiency. Main objectives of this study were to investigate the community composition of diazotrophic endophytes of S. europaea grown under natural conditions, and determine the proportion of plant-growth promoting bacterial strains able to fix N2. To quantify the abundance of diazotrophic bacterial endophytes in stems and roots of S.

A total of 94 marine actinobacterial isolates were found to be associated with 4 sponges: Callyspongia diffusa, Mycale mytilorum, Tedania anhelans, and Dysidea fragilis. Among the cultures 7 strains showed antagonism against fish and shellfish sh pathogens.
