Directory of Open Access Journals Sweden. Full Text Available Kenaf biomass is the potential as raw materials used to produce polylactic acid’s monomer which is lactic acid via fermentation by Rhizopus oryzae.
Kenaf biomass’ structure is complex due to its lignin and cellulose content. This matter had encouraged it to undergo pre- treatment process as the initial step before fermentation process can be done. In this paper, kenaf biomass was treated with dilute sulphuric acid H2SO4 to hydrolyze the cellulose content in it as well as to convert the cellulose into glucose- a carbon source oryzaae Rhizopus to grow.
Then, the fermentation process was carried out in shake flask for 3 days at pH 6. Several conditions for fermentation process had been chosen which were 25oC at rpm, 25 oC at rpm, 37 oC at rpm and 37oC at rpm. In this fermentation process, 0. Sample at 25oC at rpm produced maximum amount of lactic acid compared to others.
Biojisim rgizopus berpotensi sebagai bahan mentah dalam penghasilan monomer asid polylactic poliester alifatik termoplastik diterbitkan daripada sumber boleh diperbaharu seperti kanji jagung yang merupakan asid laktik menerusi penapaian oleh Rhizopus oryzae sejenis fungus yang hidup odyzae jirim organik yang telah mati.
Struktur biojisim kenaf adalah kompleks disebabkan kandungan lignin dan selulosanya. Hal ini menyebabkan ia perlu melalui proses pra-rawatan sebagai langkah awal sebelum proses penapaian dijalankan. Dalam kertas ini, biojirim kenaf dirawat dengan asid sulfurik H2SO4 yang dicairkan untuk menghidrolisis kandungan selulosa di dalamnya di samping menukar selulosa menjadi glukosa – sumber karbon bagi tumbesaran Rhizopus. Kemudian, proses penapaian dijalankan di dalam kelalang goncang selama 3 hari pada pH 6.
Beberapa ciri proses penapaian telah dipilih iaitu 25 oC pada rpm, 25 oC pada rpm, 37 oC pada rpm dan 37 oC pada rpm. Kenaf biomass is the potential as raw materials used to produce polylactic acid’s monomer which is lactic acid via fermentation by Rhizopus oryzae. In this rhizoous, kenaf biomass was treated with dilute sulphuric acid H2SO4 to hydrolyze the cellulose content in it as well as to convert the cell Reduction of hexavalent chromium by Rhizopus Oryzae.

Study of energetic-particle-irradiation induced biological effect on Rhizopus oryzae through synchrotron-FTIR micro-spectroscopy.
Energetic particles exist ubiquitously and cause varied biological effects such as DNA strand breaks, lipid peroxidation, protein modification, rhizops apoptosis or death.
An emerging biotechnology based on ion-beam technique has been developed to serve as an effective tool for mutation breeding of crops and microbes. In order to improve the effectiveness of ion-beam biotechnology janur mutation breeding, it is indispensible to gain a better understanding of the mechanism of rhizopks interactions between the energetic ions rhizkpus biological systems which is still elusive.
A new trend is to conduct more comprehensive research which is based jammur micro-scaled observation of the changes of the cellular structures and compositions under the interactions. Ion-irradiation on Rhizopus oryzae causes localized vacuolation, autolysis of cell wall and membrane, lipid peroxidation, DNA damage and conformational changes of proteins, which have been clearly revealed by the s-FTIR microspectroscopy.
Evidently, the elevated level of ROS in hyphal cells upon irradiation plays the key role in the caused biological effect. This study demonstrates that s-FTIR microspectroscopy is an effective tool to study the damage of fungal hyphae caused by ionizing radiation and it facilitates the exploit of the mechanism for the interactions between the rhizo;us ions and biological systems.

Dietary supplementation of additives has recently been part of strategies to deal with the detrimental effects of heat stress HS on the performance and carcass traits in broiler chicks. This study aimed to investigate the effect of dietary supplementation with the fungi Rhizopus oryzae or Chrysonilia crassa on growth, blood profile, intestinal microbial population and carcass traits in broiler chicks subjected to HS.
Comparative study on the antifungal activity of hydroalcoholic extract of Iranian Dhizopus and Royal jelly against Rhizopus oryzae.
Full Text Available Introduction: Mucormycosis is an opportunistic fungal infection. Rhizopus oryzae is major cause of mucormycosis in humans.
This disease is the most common form of the acute fungal infection with rapid progress. Iranian Propolis extract and Royal jelly are honey bee products which have been used by human over the past centuries in traditional medicine. In this study the effects of Iranian Propolis and Royal jelly were investigated against Rhizopus oryzae and Candida albicans.
The ajmur method in this study was microdilution. To perform it, the prepared dilutions of Royal jelly and alcoholic extract of Iranian Propolis were added to tubes containing Sabouraud dextrose broth culture media except to control group and then Rhizopus oryzae suspension was jamjr to all microtubes.
In the next stage, microtubes were maintained in incubator at 25oC for 48 hours and then 10 ml of the content of each microtube was transferred to Sabouraud dextrose agar media. The results indicate that Propolis might be used as an ideal combination for the treatment of fungal infections like Rhizopus oryzae.
However, clinical studies are needed to confirm the effects royzae these drugs. The typical symptoms were water-soaked lesions on bottom stem and leaf rot.
The lesion rapidly expanded and the plant was softened totally. The fungus grew vigorously at an optimum temperature 25oC and brownish colony and black sporangia were formed on potato dextrose agar medium. On the basis of mycological characteristics, analyzing sequences of internal transcribed spacer region of ribosomal DNA, and pathogenicity test on host plants, the causal fungus was identified as R. This is the first report of Rhizopus soft rot on lily caused by R. Aspergillus oryzae lebih baik dalam menghasilkan enzima protease dari pada Rhyzopus oryzae.

lineage fungus rhizopus: Topics by
PLA is a biodegradable biomaterial commonly used for biodegradable plastics. Lactic acid can be produced from lignocelluloses materials such as rice straw. Rice straw is composed of cellulose and hemicellulose that can be hydrolyzed to fermentable sugar jamhr cellulolytic and hemicellulolytic enzymes then converted to L-lactic acid by Rhizopus oryzae.
As most cellulose and hemicellulose present in lignocellulose biomass are not readily oryzad for these enzyme, pretreatment is required to alter the structure of lignocellulose substrates. This research aimed to investigate the effect of lime pretreatment on rice straw bioconversion to L-lactic acid by Rhizopus oryzae AT3.
Unpretreated and pretreated rice straw were hydrolyzed using crude enzyme that produced by Trichoderma reesei Pk1J2. Ogyzae production was carried out by solid state fermentation using rice straw and rice brand as substrate. Enzymatic hydrolysis was carried out in flasks.
Each flask was added with unpretreated or pretreated rice straw, buffer citrate solution and crude enzyme then hydrolyzed for hours. Hydrolysate was fermented by Rhizopus oryzae AT3 for days by using adsorbed carrier solid-state fermentation method with polyurethane foam as inert support material.
It involved lignocellulose structure modified that enhance enzymatic hydrolysis and resulted higher reducing sugars than unpretreated rice straw. The high reducing sugars was not related to high lactic acid yields.
Fermentation of pretreated rice straw hydrolysate by Rhizopus oryzae AT3 did not only produce L-lactic acid but oryaze other compound. On the other hand, fermentation of unpretreated rice straw hydrolysate only produced L-lactic acid. Culture media and cultivation period optimization.
