Comparative study of native microorganisms isolated from watermelon (Citrullus lanatus) waste and commercial microorganism (Clostridium thermocellum) used for bioethanol production

This study was to examine the efficiency of native microorganisms, in relation to the commercial bacterium Clostridium thermocellum ATCC 27405 for bioethanol production from waste watermelon on a pilot scale. The raw material was subjected to a grinding process for the later stage of hydrolysis under different temperatures using Aspergillus fumigatus and Leuconostoc dextranicum native microorganisms. This was followed...

Effect of the essential oils of Thymus vulgaris, Cinnamomum zeylanicum and Mentha piperita on fungal growth and morphology

This study aimed to evaluate the antifungal activity of essential oils of Thymus vulgaris L., Cinnamomum zeylanicum B. and Mentha piperita L. on some saprophytic fungi. Essential oils were extracted by hydro-distillation, and chemical composition was analysed by gas chromatography coupled with mass spectrometry (GC-MS). T. vulgaris had as major components, Thymol (35.12%), p-cymene (25.36%) and γ–terpinene...

Silver nanoparticles biosynthesized by secondary metabolites from Moringa oleifera stem and their antimicrobial properties

Biological extracts have recently shown a great potential for rapid biosynthesis of silver nanoparticles (AgNPs) with antibacterial activity. AgNPs were synthetized by reduction effect of secondary metabolites produced by the Nigrospora sp. fungus, from Moringa oleifera stem as a reducing agent and silver nitrate (AgNO3) (1 mM) as salt precursor. The synthesis of nanoparticles (NPs) was monitored through analysis of the...

Biodegradation of monocrotophos by bacteria isolated from soil

Bacteria were isolated by enrichment culture technique from groundnut (Arachis hypogaea L.) soils and tested for their ability to degrade monocrotophos in mineral salts medium under aerobic conditions in the laboratory. Based on some of the morphological and 16S rRNA gene sequence analysis, the isolates were identified as Rhodococcus phenolicus strain MCP1 and Rhodococcus ruber strain MCP-2. The initial (0-day) recovery...

An improved protocol for in vitro propagation of the medicinal plant Mimosa pudica L.

This work aimed to develop a protocol for the in vitro establishment, multiplication, rooting and ex vitro acclimatization of Mimosa pudica L., a species used in folk medicine and with pharmacological activity. Aseptic cultures were established from seeds inoculated in MS medium, without growth regulators, followed by an in vitro stabilization phase in culture medium supplemented with 2.22 μM BAP. The cultures were...

Quality characteristics of dried persimmon (Diospyros kaki Thunb) of different fruit sizes

Fruits of persimmon are considered as one of the health promoting foods which has been established as one of the major fruits in Korea. Persimmon is one of the fruits processed mainly by drying. Quality characteristics of dried persimmon prepared with different fruit sizes of cultivar Sanggandungsi were investigated. Smaller sized fruits showed significantly high weight loss as compared to bigger ones due to drying. On...
