Sixty six indigenous Saccharomyces cerevisiae strains were evaluated in stressful conditions (temperature, osmolarity, sulphite and ethanol tolerance) and also ability to flocculate. Eighteen strains showed tolerant characteristics to these stressful conditions, growing at 42 °C, in 0.04% sulphite, 1 mol L(-1) NaCl and 12% ethanol. No flocculent characteristics were observed. These strains were...

Information was sought on the cause, effects, and control of dextran in sugar manufacture in Jamaica. Storage experiments on manually harvested, burnt, whole-stalk cane revealed that Leuconostoc mesenteroides was the predominant spoilage organism. Its growth was accompanied by significant increases in dextran content and juice viscosity. However, these parameters. did not increase linearly with...

Varieties NCo376 and N14 are the most widely grown varieties in Zimbabwe and are used as control varieties in the selection programme. The success of NCo376 was due to its high yield potential throughout the year and its ability to maintain good yields, even in advanced ratoons. A study was done to compare the performances of N14 and NCo376 in the South-East Lowveld of Zimbabwe, using data from...

Many invasive species exploit the disturbed habitats created by human activities. Understanding the effects of habitat disturbance on invasion success, and how disturbance interacts with other factors (such as biotic resistance to the invaders from the native fauna) may suggest new ways to reduce invader viability. In tropical Australia, commercial livestock production can facilitate invasion b...

Cane based enterprise is one of the most flourished business in the northeastern region of Bangladesh. The purpose of the present study is to observe the pattern of production of cane based furniture in Sylhet city, identify the prospects and problems, and recommend solutions. The study reveals that most of the cane furniture enterprises (57%) is small and 36% is medium and 7% is large in size....

The NIRSystems 6500 spectrophotometer has been used to study analytes in bagasse, shredded cane, direct analysis of cane extracts (DAC), mixed juice, molasses and raw sugar. Analytes included pol, brix, dry solids, moisture, sucrose, glucose, fructose, invert, ethanol, colour, ash and starch. Although Near Infra Red (NIR) is a secondary technique, relying on conventional laboratory procedures f...

We studied the molecular composition of muscle mitochondria to evaluate whether the contents of cytochromes or adenine nucleotide translocase (ANT) or phospholipid acyl compositions reflect differences in mitochondrial oxidative capacities. We isolated mitochondria from three vertebrates of similar size and preferred temperature, the rat (Rattus norvegicus), the cane toad (Bufo marinus) and the...

This paper reports on the yield and nutritional trends over 61 years as affected by various treatments (trashed, burnt with tops either left or removed and all plots either fertilised or not fertilised) of the burning and trashing trial (BT1) at Mount Edgecombe. The overall mean residual yield benefit due to trashing was 9.3 tc/ha/an after 39 crops. The capacity of the Arcadia soil form (Vertis...

The results of nine experiments to study factors influencing the efficacy of N(phosphonomethyl) glycine (as Roundup) in killing sugarcane are reported. These factors include varying rates, methods of application, disturbance of the cane after application, the presence of dew on the foliage during application and the susceptibility of sugarcane varieties. Other factors such as season, soil type ...
