1. Screening and characterisation of gamma-aminobutyric acid (GABA) producing lactic acid bacteria isolated from Thai fermented fish (Plaa-som) in Nong Khai and its application in Thai fermented vegetables (Som-pak)
Abstract This study aimed to evaluate the capability of lactic acid bacteria (LAB) isolated from different kinds of fermented fish products (Plaa-som) on the production of γ-aminobutyric acid (GABA). Among them, isolate L10-11, identified as Lactobacillus plantarum, offered the highest GABA production and was selected for further study. The highest producti

4. Interference of aqueous and ethanolic solutions of Adiantum latifolium Lam. (Pteridaceae) leaves on in vitro Ceratocystis cacaofunesta mycelial growth
RESUMO A espécie Ceratocystis cacaofunesta é o agente etiológico do mal-do-facão, patogenia caracterizada por danos irreversíveis no sistema vascular da planta. O controle da doença é difícil e a busca por soluções alternativas e econômicas é necessária. Sabe-se que os compostos das plantas medicinais possuem atividade microbiana e podem ser uma

6. Powdered coconut water (ACP 406®) as an alternative base culture medium for in vitro culture of goat preantral follicles enclosed in ovarian tissue
Abstract This study evaluated a powdered coconut water solution (ACP 406®) as a base culture medium on the in vitro survival and development of in situ goat preantral follicles. The ovarian fragments were either immediately fixed in Carnoy solution (non-cultured control) or individually cultured for 2 or 6 days. The following culture media (all containing 1

7. Evaluation of the effects of sugarcane molasses as a carbon source for Ankistrodesmus gracilis and Haematococcus pluvialis (Chlorophyceae)
Resumo Duas espécies de Chlorophyceae, Ankistrodesmus gracilis e Haemotococcus pluvialis foram utilizadas para comparar o efeito do melaço de cana-de-açúcar como fonte de carbono. Nos dois meios de cultura de microalgas, a maior densidade celular foi obtida em meio de cultura comercial (CHU12 e WC). Durante o crescimento exponencial (1º ao 10º dia), de

8. Micropropagation, plantlets production estimation and ISSR marker-based genetic fidelity analysis of Guadua magna and G. angustifólia
RESUMO Os bambus Guadua magna e G. angustifolia têm sido propagados vegetativamente quase que exclusivamente por técnicas convencionais de propagação. Objetivou-se micropropagar, estimar a produção de mudas e analisar a fidelidade genética de G. magna e G. angustifolia por marcadores moleculares ISSR. Plantas matrizes de ambas as espécies foram culti

9. Morpho-physiological changes in Billbergia zebrina due to the use of silicates in vitro
Abstract The use of silicon in Billbergia zebrina cultivation in vitro is an alternative for optimizing micropropagation of this important ornamental plant species. The objective of the present study was to evaluate the growth and anatomical and physiological alterations in Billbergia zebrina (Herbert) Lindley plants as a function of different sources and co

10. Fast detection of Mycobacterium tuberculosis in culture-positive sputum samples by nitrate reductase activity
ABSTRACT Microscopy and bacterial culture are the main tools in the diagnosis of tuberculosis. Since the slow growth of Mycobacterium tuberculosis impairs rapid diagnosis strategies, especially in countries where the latter are the only available resources, the ongoing development of new and inexpensive tools based on mycobacterial metabolism optimizing grow

11. Phytochemical and Morphological Evidences for Shikonin Production by Plant Cell Cultures of Onosma sericeum Willd
ABSTRACT Shoot regeneration, callus growth, and biosynthesis of shikonin in callus cultures of Onosma sericeum were examined. Plant tissue culture was used as an alternative method for increasing the production of shikonin, a secondary metabolite. The isolated cultures were subjected to abiotic factors such as light, plant growth regulators, and nutritional

12. Investigation of modified platelet-rich plasma (mPRP) in promoting the proliferation and differentiation of dental pulp stem cells from deciduous teeth
Stem cells from human exfoliated deciduous teeth (SHEDs) have great potential to treat various dental-related diseases in regenerative medicine. They are usually maintained with 10% fetal bovine serum (FBS) in vitro. Modified platelet-rich plasma (mPRP) would be a safe alternative to 10% FBS during SHEDs culture. Therefore, our study aimed to compare the pro
