Study on the antagonistic mechanism of some selected fluorescent Pseudomonas strains toward Fusarium oxysporum
Academia Journal of Biology - Tập 28 Số 2 - Trang 77-81 - 2014
The presence of antifungal agents in 7 selected fluorescent Pseudomonas strains
were tested. The obtained results showed that none of them was able to decompose
chitin, laminarin and cellulose, but capable to use skim milk. All strains could
produce siderophores and cyanid, but there was a difference among them. Only the
P. fluorescens strain Ps7-1 showed the presence of phlD, one of 4 genes codin...
Some characteristics of growth process of longarm mullet (Mugil kelaartii Gunther, 1861) fish in O Loan lagoon, Phu Yen province
Academia Journal of Biology - Tập 32 Số 3 - Trang 7-11 - 2012
Longarm mullet (Mugil kelaartii) fish in lagoons O Loan, Phu Yen province is a
kind of economic species and people can catch them with big production. This
fish is a speciality of the locality due to its sweet-smelling and tastiness. At
present, aquatic resource in lagoons and inshore zone of Phu Yen province is
over-exploiting by destructive means that causes serious declining of Longarm
mullet p...
Canthium simile Merr. & Chun (Rubiaceae), a new species for the flora of Vietnam
Academia Journal of Biology - - 2012
The genus Canthium Lamk. (Rubiaceae) in the world has about 200 species
distributed in tropical, subtropical Asia and Africa. Vietnam has 9 species of
this genus [Tran Ngoc Ninh 2005]. During the time to study specimen on this
genus in Hanoi herbarium, we found one new species (Canthium Lamk.) for the
flora of Vietnam. The species Canthium simile Merr. & Chun has been discoved
from the Vu Xuan Phu...
Effect of neurotoxins from the scorpion venom Lychas mucronatus Fabricius, 1708 on the exitatory nerve
Academia Journal of Biology - - 2015
These neurotoxins decrease the action potential (AP) value depending of the
neurotoxin molecular weights (Mw). The AP rate is independent of the neurotoxin
Mw indicating the direct influence of the toxins on Na+ and K+ channels located
on the Ranhe oversize and no influence on the myelin nerve fibre state. No
dependence is observed between the neurotoxin Mw and the threshold excitation of
the nerv...
Influences of the light intensity and the NaCl concentration on the growth of two harmful marine microalgae species Prorocentrum rhathymum and Alexandrium tamarense
Academia Journal of Biology - Tập 28 Số 3 - Trang 43-48 - 2014
In Vietnam, among more than 70 harmful marine microalgae species which have been
identified [6], Prorocentrum rhathymum and Alexandruim tamarense were two
species of Dinophyta that had a very wide distribution on the coastal waters.
This study investigated the influences of the light intensity and the NaCl
concentration on the growth of these two isolated species in laboratory
conditions. The expe...
Fauna diversity in the southern part of the Kon Ka Kinh National Park, Gia Lai province
Academia Journal of Biology - Tập 43 Số 4 - Trang 139-151 - 2021
Kon Ka Kinh National Park (KKK NP) is a priority zone for biodiversity
protection in Vietnam as well as ASEAN. In order to survey the current fauna
species diversity in the southern part of the KKK NP, we conducted camera
trapping surveys in 2017, 2018, and 2019. 28 infrared camera traps were set up
on elevations between 1041 to 1497 meters. In total, there were 360 days of
survey using camera tra...

Anti-inflammatory effect of schizandriside isolated from Memecylon scutellatum Lour in lipopolysaccharide-stimulated raw 264.7 murine macrophages
Academia Journal of Biology - Tập 47 Số 4 - Trang 129-137 - 2025
Inflammation plays a key role in increasing the risk of chronic diseases such as
diabetes, rheumatoid arthritis, and cancer. The Memecylon genus is known for its
antioxidant, antidiabetic, anticancer, and antimicrobial properties. However,
the anti-inflammatory activity of the Memecylon scutellatum Lour remains poorly
understood. Therefore, this study aimed to explore the anti-inflammatory effects...

Nghiên cứu về đặc điểm của gen chalcone synthase từ \(\textit{Pueraria lobata}\) và \(\textit{Pueraria mirifica}\) tại Việt Nam Dịch bởi AI
Academia Journal of Biology - Tập 43 Số 3 - Trang 47-58 - 2021
Hai loài thuộc chi Pueraria ((Pueraria lobata (tên đồng nghĩa: Pueraria montana
var. lobata) và Pueraria mirifica (tên đồng nghĩa: Pueraria candollei var.
mirifica)) là những cây thuốc cổ truyền đã được sử dụng trong y học từ thời cổ
đại. Những cây này đã được sử dụng và trở thành cây thuốc bản địa có giá trị
thương mại quan trọng. Hiện nay, cả rễ và hoa của P. mirifica được sử dụng như
một thực p...

Activity test of antibody recombinant specificity Escherichia coli O157:H7
Academia Journal of Biology - - 2015
Antibodies are immunoglobulin molecules which originally are glycoprotein that
play role to identify and neutralize foreign agents such as viruses or bacteria.
In this study, antibody protein recombine specificity of E. coli O157:H7 which
was purified using hybrid methods. Next, antibody activity was tested by the
methods as Dot Blot, Western Blot & ELISA. The results showed thatantibody
protein s...
