1. Cultivable bacterial diversity associated with bromeliad roots from ironstone outcrops in central Brazil
Resumo Estudos sobre a diversidade bacteriana associada a plantas silvestres são raros, especialmente naqueles que crescem em associação com bromélias. No presente estudo, isolamos e identificamos bactérias epífitas e endofíticas das raízes das bromélias Dyckia excelsa, D. leptostachya e Deuterocohnia meziana ocorrentes nas “cangas” no Pantanal

2. Effect of passive ultrasonic activation on microorganisms in primary root canal infection: a randomized clinical trial
Abstract Objective: This clinical study sought to evaluate the effectiveness of passive ultrasonic activation (PUA) in eliminating microorganisms in primary endodontic infection (PEI) after instrumentation of root canals using microbiological culture and checkerboard DNA-DNA hybridization. Methodology: Twenty root canals with PEI and apical periodontitis w

4. Comparison of two rotary systems in bacteria/lps removal from endodontic infections: randomized clinical trial
Abstract: This clinical study compared the effectiveness of two rotary systems: HyFlex CM (Coltene-Whaledent, Altstetten, Switzerland) and ProTaper Next (Dentsply Sirona, Ballaigues, Switzerland) on the removal of cultivable bacteria and endotoxins from primarily infected root canals. This study was designed as a randomized single-blinded, 2-arm, clinical tr

5. Correlation Between Volume of Root Canal, Cultivable Bacteria, Bacterial Complexes and Endotoxins in Primary Infection
Resumo Este estudo clínico foi conduzido para correlacionar os níveis de endotoxinas e bactérias cultiváveis encontradas na infecção endodôntica primária (IEP) com o volume do canal radicular determinado pelo uso da Tomografia Computadorizada de Feixe Cônico (TCFC); e avaliar a diversidade bacteriana correlacionada com características clínicas.

6. Effects of Simulated Nitrogen Deposition and Precipitation Manipulation on Soil Microorganisms in the Desert Steppe of Northern China
ABSTRACT: Soil microorganisms are influenced by climate change. However, the effect of climate change on soil cultivable bacteria are unclear. In this study, the composition and diversity of the soil cultivable bacterial community were explored by a dilution–plate method, PCR, and 16S rRNA sequencing in a desert steppe of northern China after repeated NH4N

7. Molecular Identification of Cultivable Bacteria From Infected Root Canals Associated With Acute Apical Abscess
Resumo O objetivo deste estudo foi investigar a composição bacteriana de canais radiculares associados com abscesso apical agudo através de identificação molecular (16S rRNA) de bactérias cultiváveis. Duzentas e vinte cepas, de 20 casos, isoladas por cultura foram submetidas a extração de DNA e amplificação do gene 16S rRNA (PCR), seguido de seque

8. Detection of cfxA2, cfxA3, and cfxA6 genes in beta-lactamase producing oral anaerobes
ABSTRACT Purpose The aim of this study was to identify β-lactamase-producing oral anaerobic bacteria and screen them for the presence of cfxA and BlaTEM genes that are responsible for β-lactamase production and resistance to β-lactam antibiotics. Material and Methods Periodontal pocket debris samples were collected from 48 patients with chronic period

9. Functional abilities of cultivable plant growth promoting bacteria associated with wheat (Triticum aestivum L.) crops
Abstract In the pursuit of sustainable agriculture, bioinoculants usage as providers of a crop's needs is a method to limit environmental damage. In this study, a collection of cultivable putative plant growth promoting (PGP) bacteria associated with wheat crops was obtained and this bacterial sample was characterized in relation to the functional diversity

10. Evaluation of Bacillus spp. as dough starters for Adhirasam - A traditional rice based fermented food of Southern India
Abstract Adhirasam is a cereal based, doughnut shaped, deep fried dessert consumed in the southern regions of India. The dough used to prepare adhirasam is fermented and contains rice flour and jaggery. The aim of the present study was to characterize the cultivable bacteria associated with this fermented dough and to identify a suitable starter culture for

11. Quick stimulation of Alcanivorax sp. by bioemulsificant EPS2003 on microcosm oil spill simulation
Oil spill microcosms experiments were carried out to evaluate the effect of bioemulsificant exopolysaccharide (EPS2003) on quick stimulation of hydrocarbonoclastic bacteria. Early hours of oil spill, were stimulated using an experimental seawater microcosm, supplemented with crude oil and EPS2003 (SW+OIL+EPS2003); this system was monitored for 2 days and com

12. Cultivable endophytic bacteria from leaf bases of Agave tequilana and their role as plant growth promoters
Agave tequilana Weber var. 'Azul' is grown for the production of tequila, inulin and syrup. Diverse bacteria inhabit plant tissues and play a crucial role for plant health and growth. In this study culturable endophytic bacteria were extracted from leaf bases of 100 healthy Agave tequilana plants. In plant tissue bacteria occurred at mean population densitie
