Abstract Demand for sweet corn occurs drastically, especially in big cities. One of the limiting factors growth plants is size plant population and nutrient status soil. Based on this, it necessary to increase yield corn, among others, by setting right spacing applying organic granular fertilizer at dose as a source nutrients. The study was conducted Mandai, Maros, South Sulawesi using randomiz...

Broad bean (Vicia faba) mtDNA contains an open reading frame with a predicted amino acid sequence that is 41% homologous to the ribosomal protein S14 (RPS14) of Escherichia coli, and which is located 1232 ntp upstream from a gene for cytochrome b (cob). A second putative rpS14 gene occurs in broad bean mtDNA, 344 ntp upstream from a gene for ATPase subunit 9 (atp9). However, the atp9-linked rpS...

Agricultural solid waste (corn cob) has been investigated asbiosorbent for removal of metribuzin herbicide from aqueous solution. Parameters influencing extraction efficiency such as pH of the sample, contact time of sample with biosorbent, shaking time, temperature, heating time, sorbent dose were studied. Maximum sorption of metribuzinwas found at pH 5.0. The sorption of metribuzin on corn co...

Corn processing streams are characterized by high water content. Removal of water and recovery of solids are major economic and logistical challenges. New technologies are needed to modify processing streams and to reduce variability and improve quality of coproducts. The objective was to determine the effectiveness of microfiltration and ultrafiltration systems in altering water, solids (prote...

Stoichiometric and kinetic values of phenolics against DPPH (2,2-diphenyl-1-picrylhydrazyl) were determined for Andean purple corn (Zea mays L.) and red sweetpotato (Ipomoea batatas). Both crops had higher antioxidant capacity and antiradical kinetics than blueberries and higher or similar anthocyanin and phenolic contents. The second-order rate constant (k(2)) was 1.56, 1.12, 0.57, and 0.26 (m...

Xylanase production by a newly isolated Aspergillus niger SS7 was studied in submerged culture. The optimum initial pH for xylanase production was found to be 7.0. Different agricultural and industrial wastes were evaluated for their ability to induce xylanase production by this isolate. The best xylanase production (293.82 IU/ml) was recorded at 3% (w/v) corn cob hulls after 120 h of incubatio...
