A bacterium, Klebsiella pneumoniae CBL-1, was isolated from heavy metal laden industrial wastewater and could tolerate Cd (1500μg/mL), Cr (800μg/mL), Cu (600μg/mL), Pb (700μg/mL), Zn (800μg/mL) and Ni (1000μg/mL). K. pneumoniae showed optimum growth at 30oC and pH at 7. K. pneumoniae could decrease 46%, 68%, 83% and 93% of cadmium (100μg/mL) from the medium after 24, 48, 72 and 96 hours, respec...

Sunlight heats the greenhouse air temperature and tomato cracking decreases marketable product up to 90%. A shade screen reduced incoming radiation during warm and sunny conditions to reduce tomato cracking. A fuzzy controller managed greenhouse irrigation to reduce tomato cracking using as variables solar radiation and substrate temperature. The embedded controller presented 9 rules and three ...

A wide variety of waste resources are available on our planet. Egg shell waste is available in huge quantities from the food processing, egg breaking, and the hatching industries. Calcium plays a vital role in Neurospora crassa hyphal growth. Batch experiments have been performed using pure calcium salt as well as calcium in the form of pretreated egg shell waste in concentrations of 0.4, 0.8, ...

Methods 148 consecutive patients with type A TAAD were operated on during 2010 2012 (122 (82,4%) males). Their age ranged 20 – 77 years, mean 49,3 ± 9,6. Acute (subacute) dissection was in 128 (86,5%), chronic – in 20 (13,5%). The causes of aneurysms forming were: arterial hypertension, atherosclerosis – in 91 (61,5%); BAV – 18 (12,2%); MS – 16 (9,8%); cystomedianecrosis – 16 (10,8%); blunt aor...

The physicochemical and microbiological qualities of pressurized (500 MPa/30oC/20 min) and pasteurized (90oC/3 min) pennywort juices were determined during chilled storage (4oC) for 4 months. The color parameters and pH values in both processed juices exhibited no changes upon storage. Moreover, it was found that high pressure could preserve various bioactive components including ascorbic acid,...

The objective of this work was to evaluate the solid-state fermentation with Rhizopus oryzae CCT 7560 of rice bran for the enrichment of proteins and the antioxidant compounds in the fermented biomass. Fermentation was performed in tray bioreactors at 30oC for 120 h. Protein extraction was done at alkaline pH, followed by precipitation with acetone. Phenolic compounds were extracted with cold m...

Nine Aspergillus and three of Trichoderma strains were grown on wheat bran (WB) medium under solid state fermentation (SSF) for amylase production. Aspergillus oryzae LS1 produced the highest level of the enzyme. The thermal stability profile of its crude enzyme revealed the half-life time of more than 2 h at 50 and 60oC. The enzyme production was affected by strain type, incubation periods, le...

There is a growing interest worldwide to find out new and cheap carbohydrate sources for production of bioethanol. In this work, carob pod (Ceratonia Siliqua) is proposed as an economical source for ethanol production, especially, in arid regions. The carob tree is an evergreen shrub native to the Mediterranean region, cultivated for its edible seed pods and it is currently being reemphasised a...

A bacterium, MAN-511 that produced extracellular mannanase, was isolated and identified as Bacillus subtilis on the basis of 16S rDNA phylogenetic analysis. The enzyme was purified to apparent homogeneity by precipitasi ammonium sulfat 70% and Sephadex G-75 chromatography procedures. The mannanase was purified 7.6 fold and specificity of 9.3 U/mg protein. SDS-PAGE of the purified enzyme showed ...

The major problem in the fruit juice industry is associated with juice quality deterioration due to the cloud loss of juice concentrates by the enzymatic reaction of pectinmethylesterase enzyme (PME, EC 3.1.1.11). During pectin hydrolysis, pectin and water are transformed into polygalacturonic acid (pectate) and methanol by the action of PME. In this work, a low-intensity ultrasonic technique i...
