The millions of deaths from cholera during the past 200 y, coupled with morbidity and mortality in Haiti since October 2010, are grim reminders that Vibrio cholerae , etiologic agent cholera, remains a scourge. We report isolation both V . O1 non-O1/O139 early epidemic samples collected victims 18 towns across eight Arrondissements Haiti. results showed two distinct populations V. coexisted epidemic. As was sole pathogen isolated 21% clinical specimens, its role this epidemic, either alone...
Spores of Curvularia lunata were immobilized by entrapment with photo-cross-linkable resin prepolymers and incubated to form mycelium in potato dextrose broth containing cortexolone (Reichstein compound S) as an inducer steroid 11β-hydroxylase. In a buffer system 2.5% dimethyl sulfoxide, this hydroxylated hydrocortisone. The activity was comparable the free mycelium. Dimethyl sulfoxide did not inhibit hydroxylase at concentration used effective dissolving product. Of various examined, use...
Bacillus thuringiensis (Bt) biopesticides, a recognized eco-friendly pest control agent, can be used to reduce many problems associated with indiscriminate use of chemical pesticides such as environmental pollutions, public health problems, emergence resistance among pests in developing countries etc. Bt strains were, therefore, isolated from different ecosystems Bangladesh and characterized based on biochemical typing, 16S rRNA gene analysis, plasmid cry genes profiles. index was calculated...
Cholera outbreaks occur each year in the remote coastal areas of Bangladesh and epidemiological surveillance routine monitoring cholera these is challenging. In this study, a total 97 V. cholerae O1 isolates from Mathbaria, Bangladesh, collected during 2010 2014 were analyzed for phenotypic genotypic traits, including antimicrobial susceptibility. Of isolates, 95 possessed CTX-phage mediated genes, ctxA, ace, zot, two lacked toxin gene, ctxA. Also both CTX+ CTX- isolated study carried rtxC,...
Proteolytic bacteria isolated from municipal solid wastes (MSW) were identified as
Cancer treatment remains as an expensive process due to the cost of sophisticated infrastructure development well its maintenance with skilled personnel.At same time, success rate is not very inspiring since non-specific target oriented medication could cause other health complexities leading death.Research for alternative therapies aimed at minimizing side effects treatments and increasing survival rates patients includes routine explorations anticancer agents from numerous sources...
Bactrocera cucurbitae (melon fruit fly) is one of the most detrimental vegetable-damaging pests in Bangladesh. The toxicity Bacillus thuringiensis (Bt) has been reported against a few genera addition to numerous other insect species. Bt strains, harbouring cry1A-type genes were, therefore, assayed vivo 3(rd) instar larvae B. this study. biotype-based prevalence cry1 and cry1A was calculated be 30.8% 11.16%, respectively, test strains (n=224) while their greatest biotype kurstaki. Though...
Nosocomial infection is an endemic problem encountered in hospitalized patients all over the world including Bangladesh. The present prospective study was carried out on 152 who were admitted Dhaka Medical College Hospital and BIRDEM a two years period to determine organisms responsible for nosocomial infection, their antibiotic susceptibility pattern, sources impact of hospital patient management. Samples collected from postoperative wounds, post catheterized urinary tract (UTI) diabetic...
An alkaline protease from Bacillus licheniformis MZK05M9 (BlM9), a mutant strain developed in our laboratory, has been partially purified and characterized for its robustness eco-friendly application potential processing of hides skins leather manufacturing detergent industries. The enzyme was 2.70 fold with specific activity 1624U/mg comparison to crude extract by using ammonium sulfate precipitation, dialysis Sephadex G-75 column chromatography. molecular mass the 27.2 kDa as judged...
Proteases regulate important pathophysiological processes in human body such as homeostasis, blood coagulation, fibrinolysis, tumor progression, etc. These biological effects of proteases largely attribute to their applicability therapeutic agents. Imbalance coagulation and two physiological body, leads thrombosis, a leading cause cardiovascular complications including myocardial infarction, stroke, The enzymes used dissolve thrombus (blood clot) are known thrombolytic agents among them, the...
Bacillus licheniformis MZK05 was subjected to mutation by ultraviolet radiation for enhanced production of keratinase. Of 750 isolates from irradiated plates, 200 colonies that showed zone casein hydrolysis on Skim Milk Agar were cultured in liquid Feather Meal Medium containing digested feather as carbon and nitrogen source shake culture at 37ºC. The mutant B. MZK05M9 (BlM9) exhibited highest enzyme activity 170 ± 5.63 U/ml compared 74 5.29 the wild MZK05. Both strains examined presence...
Fossil fuel depletion and limitations turn scientists to develop alternative fuels as well biofuels. Cheap cellulosic biomass could be used raw materials for production of ethanol. Water hyacinth (Eichhornia crassipes) Azolla (Azolla pinnata) are the two resources considered in this study. The purpose study was produce ethanol using water substrates by yeasts presumptively identified Sachharomyces cerevisiae (Sc-SR4, Sc-MR8) Kluyveromyces marxianus (Km-SR3). For saccharification, were...
Aims: Bacillus licheniformis MZK-05 is a keratinolytic bacterium having potential in dehairing of leather and feather hydrolysis.The present study aimed at to improving the production level keratinase through gene cloning expression recombinant keratinase.Methodology results: produced an amplicon 1,156 bp polymerase chain reaction while targeting gene, kerA, responsible for enzyme keratinase.The was subsequently cloned into plasmid vector pGEX-6p-2 Escherichia coli BL21.A 58 kD GST-KerA...
Climate change-induced sea-level rise, salinity intrusion, sudden water surge, natural calamities, etc. affect the fish biodiversity, food security, and coastal livelihoods that highlight necessities of developing climate-resilient strategies e.g. adaptive aquaculture techniques. Cage culture salinity-tolerant may be an adaptation strategy to compensate for losses freshwater production by climate change in areas. Therefore, a 120-day long field experiment was conducted evaluate cage...
The present study was aimed to develop an enzyme assisted dehairing method as alternative and ecofriendly technique reduce the use of harsh chemicals in leather manufacturing. For this purpose, two proteases namely alkaline protease (601 U/ml) keratinase (132 were produced by Bacillus licheniformis MZK05M9 (BlM9) Soya molasses medium Feather mill respectively, 7.0 L bioreactor at pH 7.5 37°C. cell free preparations used together 2.5% level experiments. Three sets experiments for goat skins...
