15. The effect of sonication and heat treatment on the physicochemical, nutritional and microbiological properties of different sugarcane variants
Abstract Red sugarcane (RS) is a lesser bred of sugarcane variant in Malaysia compared to yellow sugarcane (YS), thus less data is available regarding this species. In this study, the physicochemical and microbiological properties of RS was determined and compared with YS under different conditions. Both sugarcane variants were subjected to heat and sonicati

16. Free-living diazotrophs drive castor bean nitrogen input in tropical semiarid soils
RESUMO: Existem poucos estudos sobre a diversidade microbiana em solos de mamona no ambiente semiárido tropical. Os produtos de mamona têm sido amplamente utilizados em todo o mundo e justificam a importância comercial da ricinocultura no semiárido nordestino brasileiro. Como não há qualquer tipo de fertilização, ou manutenção de resíduos da cult

17. Pseudomonas spp. and other psychrotrophic microorganisms in inspected and non-inspected Brazilian Minas Frescal cheese: proteolytic, lipolytic and AprX production potential
RESUMO: O mais consumido no Brasil, o queijo Minas Frescal (QMF) é altamente suscetível à contaminação microbiana e a produção e comercialização clandestina podem representar um risco para a saúde do consumidor. O armazenamento deste produto fresco sob refrigeração, embora mais apropriado, pode favorecer a multiplicação de bactérias psicrotró

18. Influences of Different Coating Materials on the Quality Changes of Hardboiled Salted Duck Eggs under Ambient Storage
Abstract The present study investigated the influences of selected coatings (paraffin wax (PW), chitosan (CH), whey protein isolate (WPI), and soy protein isolate (SPI)) on the quality changes of hardboiled salted duck eggs when kept under ambient temperature (30±2 oC). At 5-day intervals for 15 days, samples were tested for color (L*, C*, and h˚), shell

20. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

21. Antibacterial and Cytotoxic Potential of a Brazilian Red Propolis
Abstract Objective: To evaluate in vitro the effect of a red propolis ethanolic extract (RPE) in the prevention of growth of a cariogenic biofilm and its cytotoxic potential. Material and Methods: Minimum inhibitory and bactericidal concentrations (MIC and MBC) of RPE against Streptococcus mutans and Lactobacillus casei were determined. The cytotoxic poten

22. Antimicrobial and antibiofilm activities of phenolic compounds extracted from Populus nigra and Populus alba buds (Algeria)
The interest of this work is the discovery of new antimicrobial agents of plant origin to inhibit the formation of microbial biofilms. The present research was conducted to identify and quantify the phenolic compounds extracted from Populus nigra and Populus alba buds harvested in the area of Tizi-Ouzou (Algeria), and to evaluate their antimicrobial and anti

23. Impact of agro-farming activities on microbial diversity of acidic red soils in a Camellia Oleifera Forest
ABSTRACT The production of Camellia oleifera (oil tea), typically planted in acidic red soils in southern China, is limited by low soil fertility. Agro-farming is one way to promote soil fertility by increasing organic matter and microbial communities. To understand the impact of agro-farming activity on soil fertility, three types of agro-farming, namely, r

24. Microbial Properties of Soil in Different Coverages in the Colombian Amazon
ABSTRACT Changes in coverage affect the activity of soil’s microbial communities, affecting the carbon and nitrogen cycle. The variability of biochemical properties in different coverages (native forest, forest plantation, silvopastoral system and pasture) located in the northwest of the Colombian Amazon was evaluated. Edaphic properties were determined as
